On the Notion of Fixability of PDDL+ Plans [Extended Abstract]
Francesco Percassi, Enrico Scala, Mauro Vallati · Proceedings of the International Symposium on Combinatorial Search · 2023
PDDL+ is an expressive formalism that allows for the use of planning in hybrid discrete-continuous domains. To cope with unexpected situations, it is crucial for deployed planning-based systems to efficiently repair existing plans. In this paper, we revisit a recently proposed FIXABILITY framework for expressing and solving problems from validation to rescheduling of actions in PDDL+ plans.
