Exact weighted vertex coloring via branch-and-price
We consider the Weighted Vertex Coloring Problem (WVCP), in which a positive weight is associated to each vertex of a graph. In WVCP, one is required to assign a color to each vertex in such a way that colors on adjacent vertices are di erent, and the objective is to minimize the sum of the costs of the colors used, where the cost of each color is given by the maximum weight of the vertices ass...
متن کاملA Branch-and-Price Approach for Graph Multi-Coloring
We present a branch-and-price framework for solving the graph multicoloring problem. We propose column generation to implicitly optimize the linear programming relaxation of an independent set formulation (where there is one variable for each independent set in the graph) for graph multi-coloring. This approach, while requiring the solution of a difficult subproblem, is a promising method to ob...
متن کاملEdge-coloring Vertex-weightings of Graphs
Let $G=(V(G),E(G))$ be a simple, finite and undirected graph of order $n$. A $k$-vertex weightings of a graph $G$ is a mapping $w: V(G) to {1, ldots, k}$. A $k$-vertex weighting induces an edge labeling $f_w: E(G) to N$ such that $f_w(uv)=w(u)+w(v)$. Such a labeling is called an {it edge-coloring k-vertex weightings} if $f_{w}(e)not= f_{w}(echr(chr(chr('39')39chr('39'))39chr(chr('39')39chr('39'...
متن کاملA new DSATUR-based algorithm for exact vertex coloring
This paper describes a new exact algorithm PASS for the vértex coloring problem based on the well Keywordsknown DSATUR algorithm. At each step DSATUR maximizes saturation degree to select a new candidate Color vértex to color, breaking ties by máximum degree w.r.t. uncolored vértices. Later Sewell introduced a Graph new tiebreaking strategy, which evaluated available colors for each vértex expl...
متن کاملA Note on Vertex Coloring Edge-Weighted Digraphs
A coloring of a digraph with non-negative edge weights is a partition of the vertex set into independent sets, where a set is independent if the weighted in-degree of each node within the set is less than 1. We give constructive optimal bounds on the chromatic number in terms of maximum in-degree and inductiveness of the graph.
