A new hybrid ant colony algorithm (ACA) based on sweep algorithm and 2-opt procedure is developed for solving the capacitated vehicle routing problem (CVRP). After all the ants constructed their solutions but before the pheromone in the routes is updated, each solution might be improved by applying sweep algorithm and 2-opt procedure respectively. 2-opt is to act as an improvement heuristic within...
A new meta-heuristic method of ant colony algorithm called SbMACA is developed for solving the capacitated vehicle routing problem (CVRP). The SbMACA is different from other ACAs developed before in four aspects. First, at the beginning of constructing each new subtour during the route construction, ant does not depart from the depot, but randomly from the vertices that have not been visited so far...
