Integrating Top-down Planning with a Bottom-up Approach that Learns to Locally Combine Actions

Blazej Bulka, Marie desJardins

This paperdescribes two open problems in planning and presents preliminary ideas that could lead to potential solutions. The problems on which the paper focuses are (1) combining top-down and bottom-up reasoning to create hierarchical plans, and (2) representing domain knowledge in domains that are unpredictable or too complex to described or reasoned about precisely. The first problem is particularly relevant for plan repair and replanning. The second is relevant in situations with environmental unpredictability or imperfect information about the world.
