Abstract


In this paper we introduce techniques for state pruning atruntime in a priori unknown domains. We describe how toidentify states that can be deleted from the state-space whenlooking for both optimal and suboptimal solutions. We discussgeneral graphs and special cases like 8-connected grids.Experimental results show a speed up of up to an order ofmagnitude when applying our techniques on real-time agentcenteredsearch problems.
