Since the fourth-party logistics routing problem( 4PLRP) is a combinatorial optimization problem,the exact algorithm can not find a satisfactory solution in reasonable time. However,heuristic methods can get near-optimal solutions using a reasonable amount of computation time. The accuracy of genetic algorithm for 4PLRP has diminished with the increase of scale.Based on these disadvantage and the previous experiments,this paper proposed a memetic algorithm which combined genetic algorithm with local search ...
