Apr 19, 2019· Routing problems can be divided into two main types — node-routing problems and arc-routing problems — depending on whether the goal is to visit the nodes (locations) or the arcs (the edges connecting them) We'll give an example of each First, here's an arc-routing problem that Google needs to solve daily.

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?" It generalises the well-known travelling salesman problem (TSP) It first appeared in a paper by George Dantzig and John Ramser in 1959, in which first algorithmic.

problem and have concluded that practically all the vehicle routing problems are NP-hard (among them the classical vehicle routing problem), since they are not solved in polynomial time According to Solomon and Desrosiers (1988), the vehicle routing problem with time windows (VRPTW) is also NP-hard because it is an extension of the VRP.

Here, the most commonly used techniques for solving Vehicle Routing Problems are listed Near all of them are heuristics and metaheuristics because no exact algorithm can be guaranteed to find optimal tours within reasonable computing time when the number of cities is large This is due to the NP-Hardness of the problem.
