Faster exponential-time algorithms for approximately counting independent sets
Published 2021“…The running time of our algorithm on general graphs with error tolerance ε is at most O(20.2680n) times a polynomial in 1/ε. On bipartite graphs, the exponential term in the running time is improved to O(20.2372n). …”

Approximately Counting Locally-Optimal Structures
Published 2015“…Motivated by the difficulty of approximately counting maximal independent sets in bipartite graphs, we also study counting problems involving minimal separators and minimal edge separators (which are also locally-optimal structures). …”
