Symmetry in Combinatorial Search

Thursday, 19th August, 2010, Room 3.2.14

Toby WalshSymmetry has played an important role in many areas of artificial intelligence including constraint programming, satisfiability, planning, and automated reasoning. In this talk, I will describe recent work on formalizing and using symmetry. My talk will contain a minimum of group theory but will hopefully equip you with the tools to study symmetries within your domain of interest. I will show how such symmetry can speed up reasoning, and has led to the discovery of new results in both graph and number theory.

Some of the work described is joint with Marijn Heule, George Katsirelos and Nina Naroditskaya.
