ABSTRACT
We study how agents can cooperate to revise their plans as they attempt to ensure that they do not over--utilize their local resource capacities. An agent in a multiagent environment should in principle be prepared for all environmental events as well as all events that could conceivably be caused by other agents' actions. The resource requirements to execute such omnipotent plans are usually overwhelming, however. Thus, an agent must decide which tasks to perform and which to ignore in the multiagent context. Our strategy is to have agents selectively communicate relevant details of their plans so that each gets a sufficiently accurate view of the events others might cause. Reducing uncertainties about the world trajectory improves the agents' resource allocation decisions and decreases their resource consumptions. In fact, our experiments over a sample domain show that, on average, 50% of an agent's initial actions are planned for states it can discover it will never reach. The protocol we develop in this paper thus discovers futile actions and reclaims resources that would otherwise be wasted.

Recursive Reductions of Internal Dependencies in Multiagent Planning
ICAART 2016: Proceedings of the 8th International Conference on Agents and Artificial IntelligenceProblems of cooperative multiagent planning in deterministic environments can be efficiently solved both by distributed search or coordination of local plans. In the current coordination approaches, behavior of other agents is modeled as public external ...
Heuristic multiagent planning with self-interested agents
AAMAS '11: The 10th International Conference on Autonomous Agents and Multiagent Systems - Volume 3The focus of multiagent planning research has recently turned towards domains with self-interested agents leading to the definition of Coalition--Planning Games (CoPGs). In this paper, we investigate algorithms for solving a restricted class of "safe" ...
Multiagent Planning and Plan Execution
TAI '95: Proceedings of the Seventh International Conference on Tools with Artificial IntelligencePlanning by a multiagent system is done at two levels: first, the abstract group agent proposes a skeletal plan reasoning with the primary effects of the actions. Next, the individual agents execute the skeletal plan by reactively planning and executing ...
