Abstract

Automated planning is a complex issue and multiple avenues are researched to help solve planning problems. Composite actions like meta- actions are one such method. These meta-actions functions as shortcuts making planners skip steps they would otherwise be deciding the next action. Adding these extra actions through, increases branching factor so meta-actions can’t be added haphazardly. This paper explores the idea of removing ac- tions that are made redundant from meta-actions, thereby decreasing the overall branching factor and hopefully improve performance of planners. First some preliminaries actions are taken to en- sure that removing the actions does not result in sets of actions that can not solve problems. Afterwards, an AI tool called SMAC is used to select sets of actions based on different metrics. These selected sets are then sent to a cluster and tested alongside other sets to compare results. The results show there is broadly a gain in planning speed and coverage when removing redundant actions across domains. But each planning do- main is very distinct, so no completely common pattern to what feature makes an action more or less suited to be included/excluded could be determined.
