The ant colony algorithm solving the logistic distribution routing problem is prone to prematurity,stagnation and local optimum.In order to overcome this defect,a mixed algorithm of the MAXMIN ant system,chaos and mutation is proposed.In the simulation experiments,the maxmin ant algorithm,the mixed algorithm of the MAXMIN ant system and chaos,the mixed algorithm of the MAXMIN ant system and mutation,the mixed algorithm of the MAXMIN ant system,chaos and mutation are respectively adopted to solve the logistic distribution routing problem.Experiments show that the mixed algorithm of the MAXMIN ant system,chaos and mutation is better to enhance the global optimization capacity of the ant colony algorithm,as well as to achieve better results for the logistic distribution routing problem.
