Description

technical field [0001] The invention relates to the technical field of modern heuristic algorithms, in particular to an optimization algorithm for solving vehicle routing problems with time windows. Background technique [0002] Vehicle Routing Problems With Time Windows (VRPTW) is a typical combinatorial optimization problem that widely exists in our daily production and life, such as shopping malls, couriers delivering express delivery, and communication companies inspecting line nodes And aircraft, train, bus scheduling, etc. However, VRPTW is an NP-hard problem, and it is not easy to solve it accurately. Such problems have attracted many scientists in the world to devote their whole lives to research because of their huge scientific research value, economic value and practical application value. [0003] Among the VRPTW solution methods, the exact solution methods such as branch and bound method, cutting plane method, dynamic programming method and network flow method w...
