    22= Vehicle Routing Problem =
    33The vehicle routing problem (VRP) is a class of problems that frequently occurs in the field of transportation logistics. The original formulation of the problem
    4 has been defined in the late 1950ies and consists of a fleet of vehicles serving a set of customers with a certain demand from a single depot. The implementation in HeuristicLab covers the capacitated problem formulation with time windows (CVRPTW). Additionally, in version 3.4 pickup and delivery formulations and multiple depots are also supported. Find more information about the supported variants in a blog article: http://dev.heuristiclab.com/trac/hl/core/blog/svonolfe/vrp_34.
