A parallel improved ant colony optimization for multi-depot vehicle routing problem / Yu, B. in Journal of the operational research society (JORS), Vol. 62 N° 1 (Janvier 2011)

First, a virtual central depot is added to transfer MDVRP to the multi-depot vehicle routing problem with the virtual central depot (V-MDVRP), which is similar to a vehicle routing problem (VRP) with the virtual central depot as the origin. An improved ant colony optimization with coarse-grain parallel strategy, ant-weight strategy and mutation operation, is presented for the V-MDVRP. The computational results for 23 benchmark problems are reported and compared to those of other ant colony optimizations.
