The Long, the Short and the Random (2011.01649v2)

Abstract: We furnish solid evidence, both theoretical and empirical, towards the existence of a deterministic algorithm for random sparse $#\Omega(\log n)$-SAT instances, which computes the exact counting of satisfying assignments in sub-exponential time. The algorithm uses a nice combinatorial property that every CNF formula has, which relates its number of unsatisfying assignments to the space of its monotone sub-formulae.
