一种新的改进遗传算法——混合式遗传算法

A New Modified Genetic Algorithm——Hybrid Genetic Algorithm

针对遗传算法应用的局限性 ,把模糊思想应用到大变异操作中 ,提出了模糊大变异操作 ;并结合自适应遗传算法、最佳选择策略机制和过滤操作的思想 ,提出了一种新的遗传算法结构———混合式遗传算法 (hybridge neticalgorithm ,HGA)。HGA不仅保证了算法的全局收敛性 ,而且提高了算法的收敛速度和稳定性。算例验证了算法的优越性能。

Aiming at the limitation of GA, fuzzy - big - mutation, a new mutation method is proposed in this paper. Fuzzy - big - mutation improves the performance of big - mutation by applying fuzzy idea. Based on fuzzy - big - mutation and adaptive - GA, best - selection, filtering, hybrid genetic algorithm(HGA) is presented. HGA can converge to global optimum and improve the rate of converging and stability of GA. The computing experiments in the paper prove this.
