 ## Pitfalls and Troubleshooting
-By default, the planner performs a relevance analysis and removes components such as variables and actions that are irrelevant to achieving the goal. Although such variables and actions can in principle lead to further (simple) plans, they are classified as irrelevant and removed when translating PDDL to SAS+. If you wish to **obtain all plans** (even the non-relevant ones), please use the following options:
