RouteOpt: An Open-Source Modular Exact Solver for Vehicle Routing Problems
Despite significant advancements in exact methods for vehicle routing problems (VRPs) over the past three decades, there remains a lack of high-performing and accessible open-source solvers for researchers and practitioners. To bridge this gap, we introduce RouteOpt, the first open-source modular exact solver for VRPs, delivering state-of-the-art performance while maintaining a flexible and extensible structure. RouteOpt achieves the best performance reported in the literature on both the capacitated vehicle routing problem (CVRP) and vehicle routing problem with time windows (VRPTW).
