Abstract
An algorithm is presented for exactly counting the number of maximum weight satisfying assignments of a 2-CNF formula. The worst case running time of O(1.246n) for formulas with n variables improves on the previous bound of O(1.256n) by Dahllöf, Jonsson, and Wahlström. The algorithm uses only polynomial space. As a direct consequence we get an O(1.246n) time algorithm for counting maximum weighted independent sets in a graph.
