针对进化计算中存在收敛速度慢和易陷入局部收敛的弱点 ,本文提出将多群体和动态变异率相结合 ,对传统的进化计算进行改进。通过实验表明 ,改进的进化计算是有效的。 Aiming at the weakness of slow convergence and easy falling into local convergence in evolutionary computation, this paper proposes combining the multi-population with the dynamic mutation rate to improve the traditional evolutionary computation. Experiments show that the improved evolutionary computation is effective.
