All Concorde functions are thread-safe for programming in shared-memory parallel environments; the main TSP solver includes code for running over networks of UNIX workstations. It is very difficult – if not impossible in most computational settings – to evaluate each of those possible paths for the salesman in order to determine which provides the shortest path. The vehicle routing problem (VRP) is a combinatorial optimization and integer programming problem which asks "What is the optimal set of routes for a fleet of vehicles to traverse in order to deliver to a given set of customers?". The TSP goal is to find the shortest possible route that visits each city once and returns to the original city.
