estimates of the sizes of subcodes of Reed-Muller (RM) codes, all of the codewords in which
satisfy a given constraint. Our algorithm is based on a statistical physics technique for
estimating the partition functions of spin systems, which in turn makes use of a sampler that
produces RM codewords according to a Gibbs distribution. The Gibbs distribution is
designed so that it is biased towards codewords that respect the constraint. We apply our …
