Vehicle routing problem with time window (VRPTW) is a very important combinatorial optimization and nonlinear programming problem and it has important practical value in the field of transportation, distribution and logistics. Traditional intelligent optimization algorithms have the common defects of early convergence and easily falling into local optimal solution in solving VRPTW. An improved hybrid...
Capacitated vehicle routing problem (CVRP) is an NP hard problem and it has important practical value. For large-scale problems, it is quite difficult to achieve an optimal solution with traditional optimization methods due to the high computational complexity. In this paper, it is analyzed that the insufficiency of the traditional particle swarm optimization (PSO) to the discrete and combination...
