Review of vehicle route optimisation

Vehicle Route Optimization (VRO) is one of most important topic now-a-days as if it can be manipulated, then pollution, one of the biggest enemy of the environment may be curbed out. Basic objective of the classical problem of Vehicle Routing Problem (VRP) is to find a path in a group of city such that the length of path of all cities connected together is minimized and to solve the problem along with its numerous variations, many algorithms have been proposed in literature. In this paper, an effort has been made to study the techniques present for optimizing the route of vehicle, their working, efficiency and complexity.
