Graph coloring

Complete coloring

In graph theory, a complete coloring is a vertex coloring in which every pair of colors appears on at least one pair of adjacent vertices. Equivalently, a complete coloring is minimal in the sense that it cannot be transformed into a proper coloring with fewer colors by merging pairs of color classes. The achromatic number ψ(G) of a graph G is the maximum number of colors possible in any complete coloring of G. A complete coloring is the opposite of a harmonious coloring, which requires every pair of colors to appear on at most one pair of adjacent vertices. (Wikipedia).

Chromatic Number of Complete Graphs | Graph Theory

What are the chromatic numbers of complete graphs on n vertices? As we’ll see in today’s graph theory lesson on vertex coloring, we need exactly n colors to properly color the complete graph K_n. Intro to Graph Colorings: https://youtu.be/3VeQhNF5-rE Recall that a proper coloring (or ju

Maria Chudnovsky: Coloring graphs with forbidden induced paths

Abstract: The problem of testing if a graph can be colored with a given number k of colors is NP-complete for every k[greater than]2. But what if we have more information about the input graph, namely that some fixed graph H is not present in it as an induced subgraph? It is known that the

Discrete Math II - 10.2.2 Special Graphs: Bipartite Graphs

This video is a deeper look at bipartite graphs. We look at both the definition of a bipartite graph and using graph coloring to determine if an existing graph can be redrawn as bipartite. In addition, we model real-life scenarios with bipartite graphs in an effort to create a complete mat
