Abstract

These investigations are to find the numerical solutions of the nonlinear smoke model to exploit a stochastic framework called gudermannian neural works (GNNs) along with the optimization procedures of global/local search terminologies based genetic algorithm (GA) and interior-point algorithm (IPA), i.e., GNNs-GA-IPA. The nonlinear smoke system depends upon four groups, temporary smokers, potential smokers, permanent smokers and smokers. In order to solve the model, the design of fitness function is presented based on the differential system and the initial conditions of the nonlinear smoke system. To check the correctness of the GNNs-GA-IPA, the obtained results are compared with the Runge-Kutta method. The plots of the weight vectors, absolute error and comparison of the results are provided for each group of the nonlinear smoke model. Furthermore, statistical performances are provided using the single and multiple trial to authenticate the stability and reliability of the GNNs-GA-IPA for solving the nonlinear smoke system.

摘要

这些研究旨在寻找非线性烟雾模型的数值解,利用一种称为 gudermannian 神经网络 (GNN) 的随机框架,并结合基于遗传算法 (GA) 和内点算法 (IPA) 的全局/局部搜索术语的优化程序,即 GNNs-GA-IPA。非线性烟雾系统取决于四个群体,即临时吸烟者、潜在吸烟者、永久吸烟者和吸烟者。为了解决这个模型,基于微分系统和非线性烟雾系统的初始条件,提出了适合度函数的设计。为了检查 GNNs-GA-IPA 的正确性,将得到的结果与龙格-库塔方法进行了比较。为非线性烟雾模型的每一组都提供了权重向量的图、绝对误差和结果的比较。此外,还使用单试和多试提供了统计性能,以验证 GNNs-GA-IPA 用于解决非线性烟雾系统的稳定性和可靠性。
