为了改善遗传算法的收敛性能,提出了一种基于个体适应度的种群多样性度量函数,恰当地反映了遗传算法的进化阶段,预报了早熟收敛的趋势. 设计了基于种群多样度函数的迁移算子和交叉算子,并对交叉、变异概率等进行了动态调整,构成了具有多层迁移特点的实数编码并行遗传算法. 通过和其他优秀遗传算法对测试函数的验证比较,结果表明,该算法对于解决遗传算法中早熟、收敛速度慢等问题具有优越的性能.

In order to imp rove the convergence performance of genetic algorithms, a function measuring population diversity on the basis of the degree of individual adap tability was needed. Thismeasuring function must reflect the evolutionary stage of the genetic algorithm and forecast p remature trends app rop riately. We designed a migration op2 erator and crossover operator based on diversity of population functions, and made dynamic adjustments on cross2 over and mutation p robabilities. This structured a parallel genetic algorithm with real coding and a multi2layer mi2 gration operator. Comparative experiments were made on benchmark functions. The results showed that this algo2 rithm is obviously superior to other genetic algorithms in overcoming p roblems such as p rematurity and slow conver2 gence.
