Dealing with temporality on actions presents an important challenge to AI planning. Unlike Graphplan-based planners which alternate levels of propositions and actions in a regular way, introducing temporality on actions unbalance this symmetry.

The objective is to move the agent from its start location to its goal location in as few time interv...
