In the HGA , heuristic algorithm is used to produced initial population , self-adaptive parameter are used in copy operator, crossover operator and mutation operator .Simulated annealing algorithm is also cited ,and only some excellent chromosomes are operated by SA . In this way, HGA could improve its search ability at cost of a little more run time.

混合遗传算法在产生初始种群时引入启发式方法，采用自适应遗传参数和交替使用两种交叉算子；在搜索方式中加入模拟退火机制，采用只对部分优秀染色体进行退火操作的新策略，这样在保证增强寻优能力的情况下尽量减少运算量。
