Sequential Monte Carlo for Counting Vertex Covers in General Graphs

Vaisman, Radislav; Botev, Zdravko; Ridder, Ad - 2013

In this paper we describe a Sequential Importance Sampling (SIS) procedure for counting the number of vertex covers in general graphs. The performance of SIS depends heavily on how close the SIS proposal distribution is to a uniform one over a suitably restricted set. The proposed algorithm...
