Logistics distribution center location problem is a hot topic nowadays. We choose a medium-sized city group to study in this paper. The improved artificial immune algorithm based on similarity vector distance selection is used for the logistics distribution center location problem. The algorithm uses the threshold value to restrict concentration calculation of two antibodies from two aspects which...
Most of the existing population behavior studies are about the analysis of the population dynamic behavior of genetic algorithm, while there is little analysis of the population dynamic behavior of particle swarm optimization (PSO). Therefore, there is an urgent need for a new method to characterize the population dynamic behavior of PSO in the search process. In this paper, we propose some metrics...
