A search algorithm with an admissible heuristic function is the most common approach to optimally solve classical planning tasks. Recently DAVIES et al. (2015) introduced the solver OpSeq using Logic-Based Benders Decomposition. In this approach to planning, the master problem is an integer program derived from the operator-counting framework that generates operator counts, i.e., an assignment of integer counts for each task operator. Then, the operator counts sequencing subproblem verifies if a plan satisfying these operator counts exists, or generates a violated constraint to strengthen the master problem. In OpSeq, the subproblem is solved by a SAT solver. In this thesis, we show that this subproblem can be better solved by state-space s...
