Abstract

This study is to introduce a novel design and implementation of a neuro-swarming computational numerical procedure for numerical treatment of the fractional Bagley-Torvik mathematical model (FBTMM). The optimization procedures based on the global search with particle swarm optimization (PSO) and local search via active-set approach (ASA), while Mayer wavelet kernel-based activation function used in neural network (MWNNs) modeling, i.e., MWNN-PSOASA, to solve the FBTMM. The efficiency of the proposed stochastic solver MWNN-GAASA is utilized to solve three different variants based on the fractional order of the FBTMM. For the meticulousness of the stochastic solver MWNN-PSOASA, the obtained and exact solutions are compared for each variant of the FBTMM with reasonable accuracy. For the reliability of the stochastic solver MWNN-PSOASA, the statistical investigations are provided based on the stability, robustness, accuracy and convergence metrics.

摘要

本研究旨在介绍一种新颖的神经群体计算数值程序的设计与实现,用于对分数阶巴格利 - 托尔维克数学模型(FBTMM)进行数值处理。基于粒子群优化(PSO)的全局搜索和通过活动集方法(ASA)的局部搜索的优化程序,同时在神经网络(MWNNs)建模中使用基于迈耶小波核的激活函数,即MWNN - PSOASA,来求解FBTMM。所提出的随机求解器MWNN - GAASA的效率被用于基于FBTMM的分数阶求解三种不同的变体。为了确保随机求解器MWNN - PSOASA的精确性,将FBTMM每个变体的所得解与精确解进行比较,具有合理的准确性。为了验证随机求解器MWNN - PSOASA 的可靠性,则基于稳定性、鲁棒性、准确性和收敛度量进行统计研究。
