WebJan 1, 2024 · As a VRP heuristic, we use HGS-CVRP (Vidal, 2024), a state-of-the-art open source implementation of the hybrid genetic search originally described in Vidal et al. (2012). As the authors remark ( Vidal, 2024 p. 9), “HGS-CVRPstands as the leading metaheuristic in terms of solution quality and convergence speed”. This code has been designed to solve the "canonical" Capacitated Vehicle Routing Problem (CVRP).It can also directly handle asymmetric distances as well as duration constraints. This code version has been designed and calibrated for medium-scale instances with up to 1,000 customers.It is not designed in its … See more When using this algorithm (or part of it) in derived academic studies, please refer to the following works: Vidal, T., Crainic, T.
