In graph theory, graph coloring is a special case of graph labeling; it is an assignment of labels traditionally called "colors" to elements of a graph subject to certain constraints. In its simplest form, it is a way of coloring the vertices of a graph such that no two adjacent vertices are of the same color; this is called a vertex coloring. Similarly, an edge coloring assigns a color to each edge so tha… WebMar 21, 2024 · 5.4.1 Bipartite Graphs. A graph G = (V, E) with χ(G) ≤ 2 is called a 2-colorable graph.
