在现有文献基础上,通过理论分析,提出了交叉概率应取1.通过4个测试函数的测试结果,表明交叉概率越大,运算速度越快,平均运行代数越少,验证了通过理论分析提出的交叉概率应取1的科学性和可行性.同时克服了交叉概率难以确定以及确定交叉概率时缺少理论依据的不足. Based on the existing literature, the theoretical analysis shows that the crossover probability should be 1. The test results of the four test functions show that the larger the crossover probability is, the faster the operation speed is, and the smaller the average running algebra is, verifying that the theoretical analysis The proposed crossover probability should be scientifically and practically feasible and overcome the shortcomings of the lack of theoretical basis for determining the crossover probability and determining the crossover probability.
