The language of linear temporal logic (LTL) has been proposed as a formalism for specifying temporally extended goals and search control constraints in planning. However, the semantics of LTL is defined wrt. infinite state sequences, while a finite plan generates only a finite trace. This necessitates the use of a finite trace semantics for LTL. A common approach is to evaluate LTL formulae on an infinite extension of the finite trace, obtained by infinitely repeating the last state. We study...[Show more]
