摘要
We study the problem of constructing a (near) uniform random proper q-coloring of a simple k-uniform hypergraph with n vertices and maximum degree A. (Proper in that no edge is mono-colored and simple in that two edges have maximum intersection of size one.) We show that if q >= max {C-k logn, 500k(3)Delta(l/(k-1))} then the Glauber Dynamics will become close to uniform in 0 logn) time, given a random (improper) start. This improves on the results in Frieze and Melsted [5]. (C) 2017 Elsevier B.V. All rights reserved.
