The problem solver ABSTRIPS, a modification of STRIPS, can define an ab~traction space hierarchy from the STRIPS representation of a problem dom ain, and it can utili ze the hierarchy in solving problems. Examples of the system's performance are presented that demonstrate the si g nificant increases in problem-solving power that this approach provides. Then some further implications of the hierarchical planning approach are explored.
