Seminar

Beyond Hypertee Width: Decomposition methods without decompositions

Seminar Room 1, Newton Institute

Abstract

The general intractability of the constraint satisfaction problem has motivated the study of restrictions on this problem that permit polynomial-time solvability. One major line of work has focused on structural restrictions, which arise from restricting the interaction among constraint scopes. In this talk we consider generalized hypertree width, a structural measure that has up to recently eluded study. We give a simple proof of the tractability of instances having bounded generalized hypertree width.
