http://iridia.ulb.ac.be/wiki/index.php/History_Max_Manfrin

Plan (future work)

• Investigate the effect of parallelization on Ant Colony Optimization algorithms

Goals

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