Abstract

Ant colony optimisation techniques are usually guided by pheromone and heuristic cost information when choosing the next element to add to solution. However, while an individual element may be attractive, usually its long term consequences are neither known nor considered. For instance, a short link in a TSP may be incorporated into an ant's solution, yet, as a consequence of this link, the rest of the path may be longer than if another link was chosen. The Accumulated Experience Ant Colony used the previous experiences of the colony to guide in the choice of elements. This is in addition to the normal pheromone and heuristic cost. The results indicate that on some problems this helps to find improved solutions to the travelling salesman problem.
