Multi-colony parallel ant colony optimization on SMP and multi-core computers
Pierre Delisle, Michaël Krajecki, Marc Gravel · 2009
The purpose of this paper is to propose an effective implementation of the Ant Colony Optimization metaheuristic on actual shared-memory parallel computers. We deal with the management of multiple colonies which use a global shared-memory to exchange information. We report considerable speedups on a SMP node of multi-core processors while witnessing solution quality equal or greater than the original sequential implementation.
