Like the well-known hsp system, FF relies on forward search in the state space, guided by a heuristic that estimates goal distances by ignoring delete lists. It differs from HSP in a number of important details. This article describes the algorithmic techniques used in FF in comparison to hsp and evaluates their benefits in terms of run-time and solution-length behavior.}, number={3}, journal={AI Magazine}, author={Hoffmann, Joerg}, year={2001}, month={Sep.}, pages={57} }
