    There has been a rise in recent years in the importance of enhancing thermal transmission capacities in high-tech production settings. Conventional methods of heat transmission, which rely on base liquids including water, ethylene glycol, oil, and petroleum, struggle to attain ideal heat exchange rates due to their low thermal conductivity. Researchers have been concentrating on improving heat conductivity using nanoliquids as a means of getting around this problem. When nanoparticles are dispersed in a base fluid, a nanofluid is created with superior thermophysical characteristics to hydrogels. Due to their superior thermal qualities, they have replaced traditional coolants in radiators, electronic coolers, and heat exchangers.

    In an effort to comprehend the complexities of heat transfer, a multitude of scholars have investigated the behavior of nanoliquids as they traverse a variety of geometries, taking into account a multitude of consequential factors [1,2,3,4]. Furthermore, there has been an increase in the strategic implementation of extended surfaces, also referred to as fins, to enhance heat dissipation from a heated surface via convective, radiative, or convective–radiative mechanisms. The thermal behavior of fins is of the utmost importance in a wide range of applications, such as circuit board cooling, heat exchangers, heat-rejection mechanisms in spacecraft, and electronic component cooling systems. In addition to their traditional uses, fins have demonstrated their effectiveness in a wide range of contexts.

    An exhaustive review of the relevant literature reveals that thermal analysis of various fin designs has been the subject of an abundance of research [5,6,7,8]. The aforementioned collection of research highlights the importance of fins in enhancing the efficiency of heat dissipation mechanisms, providing valuable perspectives on the complex interaction between nanofluids and fin configurations. The ongoing pursuit of improvements in heat transmission has generated significant interest in the potential of integrating nanofluids and novel fin designs to advance thermal management in a wide range of industrial and technological contexts. In numerous industrial contexts, fin designers strive to optimize thermal transfer while reducing fin size and cost, with a specific emphasis on refrigeration, air conditioning, and the chilling of technical devices. The regulation of thermal management systems by fins guarantees their long lifespan and optimal performance. The examination of heat transport mechanisms in fins, with a specific focus on radially structured fins, is of paramount importance in the pursuit of technologically sophisticated and economically viable engineering solutions. The findings of these inquiries indicate promise for real-world applications in which efficient heat dissipation is a critical component, affecting the environmental sustainability and overall performance of diverse technical systems. Kim et al. [9] studied the impact of porous fins on heat transfer and pressure reduction in plate-fin heat exchangers, finding that permeability and porosity significantly affect friction and heat transfer rate. Fathi et al. [10] found porous-fin microchannels better than solid-fin microchannels when channel height is low. Sowmya et al. [11] studied the temperature distribution in a porous plate under convection, radiation, and internal heat generation conditions. Gireesha et al. [12] assessed thermal characteristics of inclined porous fins, while Wang et al. [13] found metallic foam heat sinks have enhanced cooling capabilities.

    In recent times, there has been a marked emphasis in the field of thermal engineering on improving heat transmission within porous media, owing to their remarkable dense thermal conductivities. Utilizing porous media, which provide a considerable surface area for heat transfer, can substantially enhance the efficiency of heat exchange apparatus. The optimization of convective heat transfer, which finds utility in combustion chambers, catalysts, and electronic component cooling, has been the subject of extensive research. Further investigations are being conducted to determine the effects of porous media on fins, which may result in improved heat dissipation for a variety of applications. Kumar et al. [14] study on radial porous fin thermal distribution found optimal heat transfer through thermal convection and an inclined magnetic field. The study also revealed that variations in magnetic field angle increased heat transfer rate while decreasing temperature. The combined efforts of the researchers [15,16,17] make a substantial contribution to the overall comprehension of thermal dynamics and entropy factors in various configurations of permeable fins. The inquiries considered various influential factors, such as magnetic forces, radiation, convection, and internal heat generation, thereby enhancing comprehension of heat transfer phenomena occurring within porous structures. The influence of a magnetic field is pervasive throughout an array of technological domains, including but not limited to metal casting, molten metal purification, and nuclear reactor coolant. The strategic utilization of an external magnetic field becomes a potent instrument for controlling convective heat transfer rates within the domain of thermal engineering. As a result, extended scholarly interest has been devoted to the examination of the impact of magnetic fields, which has generated an abundance of publications detailing the profound consequences of magnetic forces on fin heat transmission [18,19,20]. This collection of research not only enhances our fundamental comprehension of heat transfer phenomena but also demonstrates the adaptability and influence of magnetic fields in advancing thermal engineering technologies in a variety of applications where controlled heat manipulation is of the utmost importance. Selimefendigil et al. [21] investigated the effects of a magnetic field and an elastic fin on the dynamics of phase change within a cylindrical reactor embedded with a PCM-packed bed. The efficacy of the magnetic field was observed across various fin diameters and vertical orientations. Kumar et al. [22] studied the effect of an internal heat source and an electromagnetic field on the thermal distribution over a longitudinal trapezoidal porous fin. The fractional arrangement Operating (ODEs) and (PDEs) play a vital role in the fields of fluid mechanics and engineering by offering precise depictions of intricate phenomena such as those occurring in porous media, shallow water dynamics, heat transfer enhancement, biomedical fluid dynamics, hydrodynamic stability analysis, optimization of fluid transport systems, modeling of oil reservoirs, aerodynamics, and aircraft design. The methods used for the porous fin problems have been investigated by researchers by applying different techniques, such as multigrid method, multigrid-homotopy method, and wavelet multiscale method, have recently been applied to many practical application problems, such as [23,24,25]. The comprehension of all the above are facilitated by these equations. Their significance and adaptability in these domains attest to their substantial contribution to the progression of knowledge and capacities in the disciplines of fluid mechanics and engineering. Derivatives and integrals of fractional orders have undergone substantial advancements over the last ten years, as supported by an abundance of scholarly monographs and research papers devoted to the subject. A multitude of mathematical models that incorporate fractional calculus have been investigated across disciplines, including epidemiology, differential-difference equations, vibration equations, and heat transfer, among others [26,27,28]. In a recent publication [29,30,31,32], Caputo and Fabrizio presented a fractional derivative that holds significant utility in elucidating mechanical phenomena such as damage, wear, plasticity, and electromagnetic hysteresis. This novel derivative is especially well-suited for processes that do not need these effects. In order to comprehend groundwater flow, reaction-diffusion equations, and nonlinear models, scientists have implemented this derivative. Moreover, in various scientific domains, alternative fractional derivatives utilizing non-singular kernels have been suggested and implemented, demonstrating the adaptability and practicality of these mathematical principles [33,34].

    Within the domains of engineering and fluid mechanics, artificial neural networks (ANNs) function as essential instruments that find extensive utility. ANNs are utilized extensively in materials science, computational fluid dynamics (CFD), pattern recognition, predictive modeling, control systems, fault detection, optimization, fluid flow modeling, turbulence modeling, and heat transfer analysis. By extracting features from sensor data or images, these devices enable the classification of data points; they can also predict complex system behaviors, control parameters, identify abnormal behavior or defects, optimize engineering processes, and forecast material properties. Artificial neural networks (ANNs) are of great significance in tackling intricate problems in various engineering fields [35,36,37]. They provide a resilient and adaptable methodology for examining, representing, and enhancing complex systems and procedures. Scholars [38,39,40] have investigated non-Fourier irregular heat transfer in a trapezoidal porous fin, transient thermal dispersion in a moving plate, and the influence of radiation on nanofluid mixed convection in a circular cylinder by employing the Levenberg-Marquardt backpropagation artificial neural network technique. The results of this study underscore the efficacy of incorporating artificial neural networks into diverse heat transfer models. The material properties of rectangular porous fins were analyzed by Waseem et al. [41] using a neural computer model and a metaheuristic technique. They used the Cuckoo search method to find the optimal temperature profile for the process. They also analyzed a convective straight fin with fractional order and thermal conductivity variables.

    As for the novelty of this manuscript, by acknowledging the critical nature of heat transfer and the difficulties that accompany it, we present an innovative fractional model for the energy balance equation that integrates the recently developed Caputo-Fabrizio fractional derivative. The purpose of this model is to assess the performance of convective radial fins, which possess the thermal conductivity that varies with temperature. In order to tackle the complexities presented by the fractional order energy balance equation, we employ a novel methodology that integrates the state-of-the-art Cuckoo search algorithm with unsupervised ANN. This advancement signifies a new and unique contribution to the discipline, as it establishes a foundation for subsequent efforts to resolve complex fractional order nonlinear partial differential equations (PDEs) by utilizing this hybrid ANN-based cuckoo search method. By employing this technique, it becomes possible to investigate and assess the temperature distribution and temperature at the tips of convective radial fins that possess thermal conductivity. This provides significant knowledge even when subjected to conditions of varying physical parameters. By combining unsupervised ANNs with the cuckoo search algorithm, the fractional order energy balance equation not only gives us better performance but also a new concept for complex problems in heat transfer and related domains. Significantly superior to traditional analytical methods, this hybrid scheme reduces computation time and data requirements in comparison to supervised ANN, thereby offering a more effective resolution for intricate heat transfer challenges.

    There are several definitions of fractional integrals and derivatives in fractional calculus, including Caputo, Riemann Liouville [42]. Following are some of the famous fractional integrals.

    Suppose that θH1(a,b), where a>b and β[0,1] then, as per Caputo, we have

    C0Dβξθ(ξ)=1Γ(mβ)z0(ξτ)mβ1[θ(ξ)]dτ.

    We utilized the Riemann-Liouville formulation of fractional derivatives with a lower terminal at zero in our study. In the literature, the fractional order Riemann-Liouville derivative is defined as:

    L[RLDνf(t)]=1Γ(mν)dmdtmt0f(τ)(tτ)1+νmdτ(m1<νm), (2.1)

    here, f is continuous, νR, nN and Γ function is defined as under

    Γ(x)=0ettx1,R(x)>0. (2.2)

    The Mittag-Leffler function (MLF) is significant. It has a wide range of applications in the field of fractional calculus. Its significance is recognized when solving fractional-order differential equations. Podlubny [42] provides the function with two arguments α and β as:

    Eα,β(t)=k=0tkΓ(αk+β),(α>0,β>0), (2.3)

    and when we take β=1, we have the standard MLF function for one parameter.

    Figure 1 shows a schematic picture of a straight fin issue with an arbitrary cross-sectional area, Ac, perimeter P, and length b. The fin is connected to the base surface with temperature, Tb, and extends into fluid with temperature, Ta, with its tip insulated.

    Figure 1.  Geometrical description of the problem.

    The energy balance equation is thus expressed as follows:

    qrqdr=h(1ψ)(TTa)2πr+2πrψρcpgKγvf(TTa)2+J2cσ2πrt2πrtQ, (3.1)

    here Eq (3.1), q denotes the rate of heat transfer which is governed by the Fourier's law of heat conduction which is stated as follows:

    qr=2πrtkeffdT/dr, (3.2)

    calculating Eqs (3.1) and (3.2), the following relation is obtained:

    ddr(2πrtkeffdTdr)=h(1ψ)(TTa)2πr+2πrψρcpgKγvf(TTa)2+J2cσ2πrt2πrtQ. (3.3)

    In the above Eq (3.3), r and ψ represents the fin radius and porosity and the temperature dependent terms Q and h are denoted as [43]:

    Q(T)=Qq[1+λ(TTa)],h(T)=hb[TTaTbTa]p. (3.4)

    When applied at an angle of α, an inclined magnetic field with strength B0 has the following mathematical expression [44]:

    J2cσ=σB20sin2(α)u2. (3.5)

    The above Eq (3.3) can be defined as follows by applying the preceding equations:

    ddr(2πrtkeffdTdr)h(1ψ)(TTa)2πr2πrψρcpgKγvf(TTa)22πrtσB20sin2(α)u2[TTaTbTa]p+2πrtQ. (3.6)

    Additionally, the fin's energy transfer equation (Eq (3.6)) has the following boundary constraints [45]:

    T(rb)=Tb,dTdrr=rt=0. (3.7)

    The following similarity phrases are required for the suggested problem:

    Θ=TTb,Θa=TaTb,ω=λ(Tb),R=rrb,NC=hbr2bkefft,M=σB20u2r2bkeff(TbTa),Q=Qar2BkeffTb,SH=ρcpgKβr2bTbvftkeff. (3.8)

    Using the appropriate similarity terms mentioned above, we obtain the dimensionless form of Eq (3.6):

    1XddX(XdΘdX)Nc(1φ)(ΘΘa)p+1(1Θa)pSHφ(ΘΘa)2Msin2(α)(ΘΘa)+Q[1+ω(ΘΘa)]=0, (3.9)

    together with the boundary conditions

    dΘ(0)dX=0,Θ(1)=1, (3.10)

    where X represent the dimensionless porous radius, the magnitude of p is picked between 3 and 3, as it characterizes the mechanism of energy transfer in most significant applications, including material processing, and nuclear reactions. Since, we know that integer order derivatives are local in nature, these derivatives cannot correctly characterize the situation. Because its kernel is non-local and non-singular, the Riemann-Liouville fractional derivative is more suited to describing natural occurrences. As a result, we substitute the second-order derivative in equation with the novel Riemann-Liouville fractional derivative, and this Eq (3.9) changes to a fractional model of energy balance equation written as:

    1XdβdXβ(XdΘdX)Nc(1φ)(ΘΘa)p+1(1Θa)pSHφ(ΘΘa)2Msin2(α)(ΘΘa)+Q[1+ω(ΘΘa)]=0. (3.11)

    While the boundary conditions remain the same.

    The solutions to nonlinear problems are well studied in the literature, where various numerical and semi-analytical techniques are explained. The purpose behind the approximation of a solution for a mathematical relation is to find the best approximation that satisfies the given physical system more closely. To achieve this, we need to consider an efficient optimization algorithm. For this purpose, we introduce a feed-forward neural network approach for the fractional order problem (3.9) as follows:

    ˆθ(t)=mi=1ξi[f(δit+βi)], (4.1)
    dβˆθ(t)dtβ=mi=1ξidβdtβ[f(δit+βi)], (4.2)

    here, δ,β,ξ are the ANN weights, m is the number of neurons, f(t)=exp(t) is the sigmoid function, and ˆθ(t) is the approximate solution.

    Based on the previous analysis, we assume an objective function E to reduce the L2 norm for Eq (3.9). From above, we have

    MinimizeE=E1+E2, (4.3)

    where,

    E1=mean[1XdβdXβ(XdˆθjdX)Nc(1φ)(ˆθjˆθaj)p+1(1ˆθaj)pSHφ(ˆθjˆθaj)2Msin2(α)(ˆθjˆθaj)+Q[1+ω(ˆθjˆθaj)]]2 (4.4)

    and

    E2=mean[(^θ11)2+(ˆθ0)2]. (4.5)

    Here, ξj=jh, ˆθj=ˆθ(ξj), N=1h where h shows the step size and ξ0. The whole mechanism of ANN is described in Figure 2.

    As clear from the name Cuckoo, this algorithm uses the Cuckoo search (CS) strategy for finding the nest to lay their eggs there. The total search process follows the Lévy flights and random search approach. In some algorithms, like PSO and GA the local optima escapes, and the beauty of this search is that the local optima can not be escaped.

    This algorithm follows the given search path

    zt+1izti=αsH(paϵ)(ztjztk). (5.1)

    The Lévy walk equation further enhances the global search for zt+1i. Here, H(u) is the Heaviside function, zt+1i and zti are the two separate roots, pa represents the changing parameter, ϵ is the random variable, s>0 is the size of the step taken, is the element-wise product, and α is the scaling parameter.

    The CS algorithm can be further optimized with the Biogeography-based operator. In this methodology, these modified operators are used to build a new optimal solution based on hybrid Cuckoo search (HCS). In the search phase, the host bird is allowed to find the other Cuckoo eggs with higher accuracy to remove the old or to adopt it based on the optimal condition. The total population is again re-evaluated and the rate of emigration μ is chosen for each response. This rate can be defined as:

    Pμi=ESiM, (5.2)

    here, E=1 shows the maximum rate of emigration and Si=MPI is the solution of the species chosen. The total mechanism of the proposed methodology is explained in Figure 3.

    Ⅰ) Variations of Fractional order β=(1,0.9,0.8,0.7), Hartmann number M=(0,1,2) and Temperature (θ(η)): Figures 47 (a) and (b). The parameters for the graphs in Figures 47 are kept as M=(0,1,2), β=(1,0.9,0.8,0.7), Q=0.2, ω=0.1,SH=0.8,Θa=0.2,Nc=2,α=π/6. Varying the values of M=(0,1,2) in each Figure 47 and every trial have 30 runs for a different fractional order i-e for β=(1,0.9,0.8,0.7), different in every case, while the other parameters remain constant in each trial.

    Figure 4.  Graphical results obtained with variation in M=0,1,2 with fractional-order β=1.
    Figure 5.  Graphical results obtained with variation in M=0,1,2 with fractional-order β=0.9.
    Figure 6.  Graphical results obtained with variation in M=0,1,2 with fractional-order β=0.8.
    Figure 7.  Graphical results obtained with variation in M=0,1,2, with fractional-order β=0.7.

    Figure 4 (a) and (b)

    The solution plot of the Hartmann number (M) and β=1 and the non-dimensional temperature (θ) is illustrated in Figure 4(a). a dimensionless parameter that defines the intensity of a magnetic field that is exerted on a fluid with electrical conductivity. The graph demonstrates that as (M) increases, there is a concomitant increase in temperature (θ). The observed outcome can be ascribed to the Lorentz force produced by the magnetic field, which opposes the flow of the fluid and causes a rise in temperature. Furthermore, the graph visually represents the progression of temperature (θ) in relation to (M), underscoring that the Lorentz force becomes more pronounced as the strength of the magnetic field increases. The plot was generated utilizing the Hybrid Cuckoo Search algorithm, which is a neural network technique.

    ● The parameters for the graphs in Figures 47 are kept as β=(1,0.9,0.8,0.7), Q=0.2, ω=0.1,SH=0.8,Θa=0.2,Nc=2,α=π/6. Varying the values of M = 0, 1, 2 in each Figures 47 and every trial have 30 runs for a different fractional order i-e for β=(1,0.9,0.8,0.7), different in every case, while the other parameters remain constant in each trial.

    The visual depiction emphasizes the substantial influence that the Hartmann number has on the temperature of the system. A stronger Lorentz force results from a more pronounced magnetic field, which is denoted by an increased number (M). This force, which acts in opposition to the fluid's flow, causes the temperature to rise. The graph in Figure 4(b) depicts the residual errors that arise from temperature variations for various values of M (0, 1, 2). The defects, which occur within a specified range for every value of M, serve as an indication of the fractional order β residual in this case lie between 109 and 1014. Residual errors, also known as residuals, are mathematical or statistical discrepancies that arise from the opposition between predicted and observed values.

    The computation involves the subtraction of predicted values from observed values. Critical for determining whether a model fits its data and for detecting patterns, trends, and outliers is residual analysis. Residuals ought to be centered on zero and distributed at random, which would indicate that the model has captured the underlying data patterns. In disciplines such as statistics, economics, finance, and machine learning, residual analysis is utilized to assess the performance and dependability of predictive models. The insights gained from this analysis regarding the behavior of the system and the influence of fractional orders on temperature fluctuations are of great value.

    Figure 5 (a) and (b)

    The relationship between the Hartmann number (M = 0, 1, 2) and the non-dimensional temperature is depicted in the solution plot of Figure 5(a). This non-dimensional temperature parameter defines the electrical conductivity-induced effect of a magnetic field on a fluid. The results of the analysis underscore the significance of the Lorentz force in this phenomenon and the impact of the Hartmann number on temperature, as illustrated by the Hybrid Cuckoo Search algorithm. The implications of these findings f The temperature variation (θ) as the Hartmann number (M) increases is graphically represented in the graph. An increase in the Hartmann number is correlated with a proportional rise in temperature, as indicated by the observed trend. The observed behavior can be ascribed to the Lorentz force produced by the magnetic field, which acts in opposition to the flow of fluid and causes an increase in temperature. By generating the solution plot, the Hybrid Cuckoo Search algorithm demonstrates its effectiveness in optimizing the system parameters. Using fractional order β, the parameters for the diagrams in Figure 5(a) are maintained. By manipulating β from 1 to 0.9, the graph investigates the effect of fractional order on temperature (θ) in greater detail. Significantly, a reduction in fractional order is accompanied by a corresponding decrease in temperature, as is evident from Figure 5(a). The incremental improvement of values as β decreases underscores the fractional order sensitivity of the system. In brief, the graph adeptly illustrates the intricate relationship that exists among the Hartmann number, fractional order, and temperature with respect to the influence of a magnetic field on a fluid system. The residual errors caused by temperature variations for various M values are illustrated in Figure 5(b), which represent fractional order defects. Mathematical or statistical disparities between predicted and observed values constitute residuals. They ought to be random and equal to zero, which would indicate model accuracy. These Residuals errors fall between 106 and 1014. In disciplines such as statistics, economics, finance, and machine learning, residual analysis is utilized to evaluate the efficacy of predictive models and the behavior of systems.

    Figure 6 (a) and (b)

    This research investigates the correlation between non-dimensional temperature and the Hartmann number (M = 0, 1, 2), with a particular emphasis on the Lorentz force and its influence on temperature, shown in Figure 6(a). The efficacy of the Hybrid Cuckoo Search algorithm in identifying temperature variation is demonstrated by its use in optimizing system parameters. The Figure 6(a), illustrates a positive correlation between temperature and Hartmann number, which can be attributed to the Lorentz force generated by the magnetic field. Additionally, the fractional order sensitivity of the system is emphasized. The fractional order is employed to preserve the parameters of the diagrams shown in Figure 6(a). By manipulating from 1 to 0.9 and then 0.8, the graph provides a more comprehensive examination of the impact that fractional order has on temperature (θ). Unsurprisingly, a decrease in temperature corresponds to a reduction in fractional order, as illustrated in Figure 6(a).

    Residual errors associated with temperature fluctuations for different values of M are illustrated in Figure 6(b). Residuals are quantified as discrepancies from the anticipated values that fall within a designated range. The residual errors are identified to be concentrated between 107 and 1012. The defined range facilitates comprehension of the extent to which actual values deviate from predictions. Residuals function as a numerical indicator of the discrepancies that exist between anticipated and realized values. Residuals are anticipated to be random and centered on zero in an accurate model, signifying a negligible margin of error in the predictions. Its significance is paramount in assessing the efficacy of predictive models and comprehending the behavior of systems.

    Figure 7 (a) and (b)

    A continuance of the fractional order reduction from β=1 to β=0.7 for different values of the Hartmann number M is illustrated in Figure 7(a). As a consequence of this decrease, temperature values are likewise reduced in comparison to the preceding three instances The reduction in fractional order from β=1 to β=0.7, for M=0,1, and 2 is visually represented in Figure 7(a), The graph visually represents the subsequent decrease in temperature measurements. The observed decrease in value occurs at M = 0, 1, and 2, underscoring the impact that fractional order has on the temperature response of the system. The graph highlights the degree of sensitivity that the system exhibits towards fractional order alterations. Comprehending this sensitivity is of the utmost importance in order to optimize system parameters and accurately forecast temperature fluctuations. This graphical representation facilitates the understanding of the complex correlation between temperature, M values, fractional order, and the former, thereby providing practitioners and researchers with valuable insights for optimizing systems and fine-tuning parameters. Residual errors, shown in Figure 7(b), which are measured as differences between expected and observed values, are critical for evaluating the effectiveness of predictive models and comprehending the behavior of systems. The residual errors are identified to be concentrated between 107 and 1011. They are inter-concentrated.

    When the magnetic field angle varies, the Hartmann number rises and the rate of heat transfer increases. A decrease in temperature results from increasing the Hartmann number from 2 to 3. As M values increase, the magnetic influence and corresponding magnetization strength increase as well, regulating convective heat transfer and increasing the fin's average heat transmission. Moreover, the buoyancy force is triggered by the magnetic field, which permits the fin to disperse additional heat. Consequently, there is an acceleration of the heat transfer rate from the fin. The feature of thermal distribution in the radial porous fin with and without magnetic field is exhibited in Figures 47. The temperature distribution in the fin with a magnetic field inclined at an angle of π/6 is indicated by the lower curve of the thermal profile, whereas the higher temperature curve is observed in the absence of a magnetic field. This suggests that fins with an angled magnetic field transmit heat at a faster rate. Additionally, there is a difference in these two curves. Physically, a magnetic field and the magnetic force that it attracts restrict the convection heat transport process, increasing the average heat transmission through the fin. This relationship is applied in the construction of nuclear reactors, where efficient heat removal is necessary to prevent overheating. The impact of the Hartmann number, a fundamental feature of electrically conducting fluids used as reactor coolants, must be carefully considered in the design of the cooling system to ensure the safe and effective operation of nuclear reactors.

By situating the fitness values between 6×105 and 7×105, one can discern that the implementation of the M Hartmann number has enhanced the algorithm's performance. In contrast to M = 0, the curve's flattened profile indicates a more secure convergence. A post-peak decline indicates that the M Hartmann number has been searched for its optimal value, demonstrating that it has a substantial impact on the efficiency of the algorithm.

    ● M = 2 and β=0.8: Figure 6(e).

    When M = 2 and β=0.8 Following nine independent trials, the fitness curve for M = 2 attains its optimum value.

    Ⅲ) Variation of fractional order (β=1,0.9,0.8,0.7), Temperature (θ) and the convective–conductive parameter (Nc = (1, 2, 3)):

    Nc=(1,2,3),M=3,(β=1,0.9,0.8,0.7), Q=0.2,ω=0.1,Θa=0.1,α=π/6.

    Varying the values of Nc=1,2,3 in each Figure 811 and every trial have 30 runs for different fractional orders i-e for (β=1,0.9,0.8,0.7), different in every case, while the other parameters remain constant in each trial. Figures 811 (a) and (b): It is essential to analyze temperature, the convective-conductive parameter Nc, and fractional order beta in order to comprehend the system's behavior under various conditions. Determining meaningful conclusions is made possible by the insightful solution graphs and residual errors presented in Figures 811 (a) and (b) for varying parameters.

    Figure 8.  Graphical results obtained with variation in M=0,1,2 with fractional-order β=1.
    Figure 9.  Graphical results obtained with variation in Nc=1,2,3 with fractional-order β=0.9.
    Figure 10.  Graphical results obtained with variation in Nc=1,2,3 with fractional-order β=0.8.
    Figure 11.  Graphical results obtained with variation in Nc=1,2,3 with fractional-order β=0.7.

    ● The fluctuation of the convective-conductive parameter Nc is illustrated in Figure 8(a) when the fractional order β is set to 1. As Nc increases from 1 to 3, a distinct trend of decreasing temperature is observed. This observation implies that elevated values of Nc are associated with reduced temperatures, thereby establishing a robust inverse correlation between Nc and temperature. From these plots, the significance of Nc in influencing temperature dynamics is evident. The solution plot of temperature versus Nc is illustrated in Figure 9(a) for a β value of 0.9. Consistent with prior research, the observed pattern indicates that a rise in Nc results in a corresponding decline in temperature. This uniformity strengthens the correlation between Nc and temperature behavior.

    The influence of Nc on temperature is additionally examined in Figure 10 (a) and (b), specifically for β values of 0.8 and 0.7, respectively. In both instances, the temperature decreases as Nc increases from 1 to 3. This finding supports previous research and underscores the strong correlation between Nc and temperature when considering various fractional orders. It is important to highlight that the fractional order beta β is a crucial factor in influencing the dynamics of temperature. A reduction in temperature is equivalent to a decrease in the fractional order beta, as depicted in Figures 811 (a). This suggests that as fractional orders decrease, the resulting temperatures become more precise. A complete comprehension of the system's behavior requires an awareness of the temperature effect produced by Nc and β combined. In summary, the solution plots that were displayed underscore the complex interaction that exists among Nc, fractional order beta β, and temperature. The insights gained from the observed trends regarding the effects of parameter variations on the thermal behavior of the system are of great value. Additional investigation and examination of these correlations may enhance our comprehension of the intricate physical mechanisms at play.

The residual errors for fractional order beta equal to 1 and Nc values of 1, 2, and 3 are contained within the range shown in Figure 8(b). This finding suggests that the HCS-ANN model exhibits satisfactory performance under the given conditions. The limited extent of variation implies a consistent and dependable forecast for temperature in light of these conditions. The analysis is expanded to include fractional order beta equal to 0.9 and Nc values of 1, 2, and 3 in Figure 9(b). The residual errors are, which indicates that despite a minor reduction in fractional order, the model retains its accuracy. This further validates the HCS-ANN model's ability to accurately represent temperature variations when convective-conductive parameters are altered. The residual errors for fractional order beta equal to 0.8 and Nc values of 1, 2, and 3 are all within the acceptable range, as shown in Figure 10(b). Notwithstanding the reduction in fractional order and possible escalation in complexity, the model continues to demonstrate satisfactory performance, as errors continue to fall within an acceptable range. Finally, the residual errors for fractional order beta equal to 0.7 and Nc values of 1, 2, and 3 are illustrated in Figure 11(b). The range of residual errors is, indicates that the predictive capabilities of the HCS-ANN model are preserved even when convective-conductive parameters are higher and fractional order is lower.

    The normal fitness curve for Nc = 1 and β = 1 reaches its maximum after 12 independent trials, remaining within the range, as shown in Figure 8(c). This implies that the algorithm attains stability and optimal performance following a specific threshold of executions. The normal curve depicted in Figure 8(d) for Nc = 2 and β = 1 is bounded by, and after 12 independent trials, it displays a comparable peak. The normal curve illustrated in Figure 8(e) is characterized by a flattened shape within the range, suggesting enhanced stability in comparison to the curves illustrated in Figures 8 (c) and (d) for Nc = 3 and BETA = 1. The observed flattening implies that as Nc increases, performance becomes more consistent and optimal outcomes ensue.

The curve remains between for Nc = 2 after eight independent trials, shown in Figure 9(d). In contrast, the range is for Nc = 3 and β = 0.9, and the curve reaches its maximum after 12 independent iterations as in Figure 9(e). The aforementioned observations underscore the influence of Nc on the fitness curve and the consequent convergence characteristics when applied to various fractional orders.

    ● Nc = 1, 2 and 3 and β = 0.8 Figure 10 (c)(e)

    As shown in Figure 10(c), the normal fitness curve for Nc = 1 and β = 0.8 reaches its optimum after 12 independent trials, remaining within the range. This suggests that the algorithm achieves optimal performance and stability after a predetermined number of executions. The normal curve illustrated in Figure 10(d) for Nc = 2 and β = 0.8 is delimited by, and it exhibits a similar peak after 8 independent trials and te curve is more flattered than that for Nc = 1. The normal curve depicted in Figure 10(e) exhibits a more uniform shape throughout the range, reached to its peak after 12 trials, indicating improved stability when compared to the curves for Nc = 3 and β = 0.8 shown in Figure 10 (c) and (d). The flattening observed suggests that as Nc increases, there is a corresponding increase in performance consistency, leading to optimal outcomes.

    ● Nc = 1, 2 and 3 and β = 0.7 Figure 11 (c)(e)

    Significant insights into the algorithm's performance are uncovered by the normal fitness curves produced by HCS-ANN for 30 independent trials, taking into account various values of the convective-conductive parameter (Nc) and a fractional order β of 0.7. The subsequent enhanced analysis offers a more comprehensive and logical depiction:

    The optimal point of the normal fitness curve, which corresponds to Nc = 1 and fractional order β = 0.7, is reached after 12 independent trials and remains consistently within the range, as depicted in Figure 11(c). After a predetermined number of iterations, this behavior indicates that the algorithm converges to an optimal solution, attaining stability and optimum performance.

    In Figure 11(d), the normal fitness curve is circumscribed by for Nc = 2 and β = 0.7. It exhibits a comparable peak that transpires marginally earlier, subsequent to ten independent trials. It is worth noting that the curve displays a more angular form in comparison to the one at Nc=1. The observed flattening implies a potential increase in stability and a more consistent performance, which are both suggestive of enhanced convergence characteristics for the specific combination of parameters in question.

    The performance is further illustrated in Figure 11(e) when Nc = 3 and β = 0.7. The curve exhibits a uniform shape throughout the entire range and attains its maximum value after eight trials. The observed flattening in comparison to Figure 11 (c) and (d) indicates that performance consistency improves proportionally with the convective-conductive parameter (Nc). This implies that as Nc increases, outcomes become more stable and dependable, ultimately resulting in the attainment of an optimal solution.

    To summarize, the performance of HCS-ANN is significantly impacted by the interaction between the fractional order β and the convective-conductive parameter (Nc), as illustrated by the trends in Figures 11 (c)(e). The observed increase in curve flattening with Nc indicates enhanced stability and convergence characteristics of the algorithm. This observation offers significant insights into the behavior of the algorithm across various parameter configurations.

    The fitness graphs of the HCS-ANN Deep Learning Algorithm Figures 811 (f) offer significant insights regarding its convergence and optimization characteristics. The graphs illustrate effective convergence, as the average fitness value attains stability in the vicinity of function evaluations. The convergence of individual particles is observable through the aggregation of blue lines encircling the red line, thereby augmenting the consistency and reliability of the algorithm. Rapid convergence to optimal solutions is evidenced by the algorithm's overall trend, which demonstrates its efficacy in resolving complex optimization problems. The mean fitness value of the population stabilizes around function evaluations at approximately for Fractional order β = 1, for β = 0.9, for β = 0.8, and for β = 0.7 all are same, around function evaluations shown in Figures 811 (f) respectively. In order to comprehend the convergence behavior of the optimization algorithm, it is vital to conduct an analysis of the population's mean fitness value, specifically with regard to various fractional orders β. The stabilization of the mean fitness value for different fractional orders around a specific number of function evaluations is depicted in Figures 811(f).

    The mean fitness value stabilizes in Figures 811(f) around function evaluations of approximately when [β = 1]. This implies that when the fractional order is set to 1, the optimization algorithm converges to a stable solution across a consistent range of function evaluations. The reliability of the algorithm in locating the optimal solution is indicated by the stability of the mean fitness value.

    In a similar fashion, the mean fitness value stabilizes at around approximately function evaluations when [β = 0.9], the same is for, as illustrated in Figures 911 (f) respectively.
