Summary on Grant Application Form
A major difficulty affecting practical exploitation of domain-independent planning technology is the complexity of the search problem. Exploiting symmetries in the structure of a problem can be a very effective way of pruning search branches, yielding up to exponential improvements in performance. The goals of this project are to extend some preliminary work, published by the investigators, into automatic identification and exploitation of certain classes of symmetries in the context of planning. A key advance over related work is the dynamic identification and breaking of symmetries during search. We will develop symmetry-breaking techniques that can be used as optimizations in a variety of alternative planning and search strategies.
