WebJul 27, 2014 · Contraction and Greedy Coloring Algorithms. Graph coloring is computationally hard and it has been a research topic for many years. Most of the algorithms can be broadly categorized in one of two main topics “Contraction” and “Greedy Coloring”. Greedy Coloring focuses on carefully picking the next vertex to be colored. Webprised of vertices of the same color in a proper coloring are all independent. 13.2 Greedy Coloring A simple greedy algorithm for creating a proper coloring is shown below. The basic idea is do a single pass through all vertices of the graph in some order and label each one with a numeric identi er. A vertex will labeled/colored with the lowest ... ciff-ost
