On Sampling Colorings of Bipartite Graphs
We study the problem of efficiently sampling k-colorings of bipartite graphs. We show that a class of markov chains cannot be used as efficient samplers. Precisely, we show that, for any k, 6 ≤ k ≤ n {1/3-ε}, ε > 0 fixed, almost every bipartite graph on n+n vertices is such that the...
