• Libcmtvrptw.a, a C++ library for solving the capacitated multi-trip vehicle routing problem with time windows (CMTVRPTW) and its variants developed in "An exact price-cut-and-enumerate method for the capacitated multi-trip vehicle routing problem with time windows." 

• LibcmtvrptwX.a, a C++ library for solving the CMTVRPTW, CMTVRPTW-LT, and CMTVRPTW-R instances with up to 200 customers.  It applies the DeLuxing algorithm. The complete numerical results can be found in the paper and its online companion.

• DeLuxing, a C++ implementation of the DeLuxing algorithm developed in "DeLuxing: deep Lagrangian underestimate fixing for column-generation-based exact methods." 

• RouteOpt, an open-source CVRP and VRPTW solver implemented in C++ and achieving state-of-the-art performance.
