Approximation Algorithms for Multicoloring Planar Graphs and Powers of Square and Triangular Meshes
A multicoloring of a weighted graph G is an assignment of sets of colors to the vertices of G so that two adjacent vertices receive two disjoint sets of colors. A multicoloring problem on G is to find a multicoloring of G. In particular, we are interested in a minimum multicoloring that uses th...
