Studies in Solution Sampling
Vibhav Gogate and Rina Dechter |

Abstract
We introduce novel algorithms for generating random solutions
from a uniform distribution over the solutions of
a boolean satisfiability problem. Our algorithms operate
in two phases. In the first phase, we use a recently introduced
SampleSearch scheme to generate biased samples
while in the second phase we correct the bias by using
either Sampling/Importance Resampling or the Metropolis-
Hastings method. Unlike state-of-the-art algorithms, our algorithms
guarantee convergence in the limit. Our empirical
results demonstrate the superior performance of our new algorithms
over several competing schemes.
