Counting solutions to random cnf formulas

Webdom CNF-XOR formulas. We empirically demon-strate that a state-of-the-art SAT solver scales ex-ponentially on random CNF-XOR formulas across a wide range of XOR-clause densities, peaking around the empirical phase-transition location. On the theoretical front, we prove that the solution space of a random CNF-XOR formula ‘shatters’ WebThis work gives the first efficient algorithm to approximately count the number of solutions in the random k-SAT model when the density of the formula scales exponentially with k, using a recent technique by Moitra to work for random formulas with much higher densities.
