Extracting Landmarks and Ordering them for Planning

摘要

We identify important intermediate planning goals, which we refer to as landmarks and present a method for extracting landmarks from an input planning problem. We also present a method for finding orders between landmarks which can be used during planning. These methods have been implemented and integrated with an example planning system. In the paper we present results that support our expectation that these orders can lead to improved planning performance (both in terms of speed and plan quality).
