Plan (future work)

  • Investigate the effect of parallelization on Ant Colony Optimization algorithms

Parallelization of ACO algorithms

Milestone I: Jan - Mar 2006

  • Acquire practical experience in explicit parallelization on ACO algorithms
    • Start from sequential ACOTSP and implement various MPI variants
      • Sync
        • Multicolony - completly-connected
          • each colony identifies the best bsf and grab it
          • the colony with the worst bsf grab the best bsf
        • Multicolony - ring
        • Multicolony - hypercube
        • Single colony, multi local search
      • Async
        • Multicolony - completly-connected
          • each colony identifies the best bsf and grab it
          • the colony with the worst bsf grab the best bsf
        • Multicolony - ring
        • Multicolony - hypercube
        • Single colony, multi local search

Milestone II : Apr - Jun 2006

  • Acquire practical experience in implicit parallelization on ACO algorithms
    • Start from sequential ACOTSP and implement various OpenMP variants

Goals

  • Acquire practical experience in parallelization on ACO algorithms (both explicit and implicit parallelism)
  • Submit paper to ANTS 2006 (on explicit parallelism - MPI)
