Abstract
Let G be a weighted graph such that each vertex v has a positive integer weight \( w\left( v \right) \) . A weighted coloring of G is to assign a set of \( w\left( v \right) \) colors to each vertex \( v \) so that any two adjacent vertices receive disjoint sets of colors. This paper gives an efficient algorithm to find the minimum number of colors required for a weighted coloring of a given series-parallel graph G in time \( O\left( {nw_{max} } \right) \) , where n is the number of vertices and \( w_{max} \) is the maximum vertex-weight of G.
