We consider the problem of uniformly sampling proper 3‐colorings of an m × n rectangular region of ℤ2. We show that the single‐site “Glauber‐dynamics” Markov chain is rapidly mixing. Our result complements an earlier result of Luby, Randall, and Sinclair, which demonstrates rapid mixing when there is a fixed boundary (whose color cannot be changed). © 2004 Wiley Periodicals, Inc.
