A multi-agent based cooperative approach to scheduling and routing

Simon Martin, Djamila Ouelhadj, Patrick Beullens, Ender Ozcan, Angel A. Juan, Edmund K. Burke
2016 European Journal of Operational Research  
In this paper, we propose a general agent-based distributed framework where each agent is implementing a different metaheuristic/local search combination.  ...  Moreover, an agent continuously adapts itself during the search process using a direct cooperation protocol based on reinforcement learning and pattern matching.  ...  Each metaheuristic agent conducts its search using the messaging structure defined in the ontology for scheduling and routing and uses no problem specific data and as such is generic.  ...
