Abstract

We investigate a refined recursive coloring approach to construct balanced colorings for hypergraphs. A coloring is called balanced if each hyperedge has (roughly) the same number of vertices in each color. We provide a recursive randomized algorithm that colors an arbitrary hypergraph (n vertices, m edges) with c colors with discrepancy at most O(formula presented). The algorithm has expected running time O(nmlog c). This result improves the bound of O(formula presented) achieved with probability at least 1\2 by a random coloring that independently chooses a random color for each vertex (fair dice coloring). Our approach also lowers the current best upper bound for the c-color discrepancy in the case (formula presented) and extends the algorithm of Matoušek, Welzl and Wernisch for hypergraphs having bounded dual shatter function to arbitrary numbers of colors.
