摘要:

针对强制进化随机游走算法(RWCE)在优化质量交换网络进程中, 存在部分个体在竞争中长期处于劣势状态以及个体结构高度相似的现象, 提出带有个体淘汰的RWCE算法优化质量交换网络。即在一定的周期内, 通过对种群中个体优化状态的实时监控, 首先对个体的网络结构进行标准化处理, 以此识别出结构中相似的质量交换器, 再根据其数目评价个体的结构相似度, 将种群中的个体划分为若干个集团, 并以年度总费用作为评价个体优化性能的指标, 淘汰种群中的劣势和相似个体, 以此加强种群间个体的信息交流, 提升个体优化活力和种群多样性, 同时有效增强算法优化质量交换网络的全局搜索能力。将该方法应用于2个质量交换网络实例中, 优化结果均优于文献最优结果, 说明该方法能改变结构的进化方向, 激励种群间个体的差异性进化和保持个体的优化活力, 且有效提升算法的全局寻优性能。

Abstract:

In the process of optimizing the mass exchange network by random walk algorithm with compulsive evolution, some individuals are in a long-term disadvantaged state in the competition and the individual structure is highly similar. RWCE algorithm with individual elimination is proposed to optimize the mass exchange network. That is, in a certain period, through the real-time monitoring of the optimal state of the individuals in the population, the network structure of the individual is first standardized, so as to identify the similar quality exchangers in the structure, and then evaluate the structural similarity of the individual according to its number. Divide the individuals in the population into several groups, and use the total annual cost as an indicator to evaluate the individual optimization performance, and eliminate the disadvantaged and similar individuals in the population. Strengthen the information exchange of individuals between populations, improve individual optimization vitality and population diversity, and effectively enhance the global search ability of the algorithm to optimize the mass exchange network. Applying this method to two examples of mass exchange networks, the optimization results are better than the best results in the literature, indicating that the method can change the evolution direction of the structure, stimulate the differential evolution of individuals between populations and maintain the optimization vitality of individuals, and effectively improve the global optimization performance of the algorithm.
