Cresswell, S. and Coddington, A.M. (2004) Compilation of LTL goal formulas into PDDL. In: European Conference on Artificial Intelligence (ECAI 2004), 2004-08-22 - 2004-08-27, Valencia, Spain.
Temporally extended goals are used in planning to express safety and maintenance conditions. Linear temporal logic is the language often used to express temporally extended goals. We present a method for compiling LTL goal formulas into Planning Domain Definition Language (PDDL), which is handled by many AI planners. The compilation process first constructs a finite state machine representing all reachable progressions of the goal formula, then modifies the planning domain and problem definition so that the state of the FSM is tracked.
