Aiming at the above,the following strategy is suggested: adding the tracking and replacing mechanism to every searching node;counting the stagnation times of a node at a certain station in its searching route;if the times oversteps the allowable value,a new node randomly arises in the solution space to replace the stagnating one for improving the searching efficiency.

但常规的差分进化算法存在停滞现象,容易使算法收敛停止,鉴于此本文提出一种改进的差分进化算法,对算法提出另一个终止条件并且重新产生初始个体,对种群大小N,变异率F,交叉率CR其中的也可作调整,在计算过程中引入精英策略,既防止了停滞现象也加快了收敛速率并使算法能收敛到全局最优。
