单纯同伦算法的改进遗传算法
An improved genetic algorithm based on PL homotopy methods
摘要
Abstract
For the shortcoming of low convergent speed and poor stability of the simple genetic algorithm in practical applications, an improved genetic algorithm is presented based on PL homotopy methods, and the n-dimensional solution space of the optimization problem is transformed as n+1 dimensional. The algorithm follows the path of the homotopy parameter to find the optimal solution, using the simplex subdivision with refining network diameter to improve the accuracy of the target solution step by step. Meanwhile, the vertex integer label information of simplex subdivision is used as convergence criteria to improve the stability of the simple genetic algorithm. The examples show that the improved genetic algorithm is superior to the simple genetic algorithm, the algorithm of the aspects of accuracy and accelerating convergence.关键词
