WebJun 14, 2024 · Graph Coloring Problem. The Graph Coloring Problem is defined as: Given a graph G and k colors, assign a color to each node so that adjacent nodes get different colors. In this sense, a color is another word for category. Let’s look at our example from before and add two or three nodes and assign different colors to them. WebApr 26, 2024 · Map coloring “Map-coloring” is a famous toy problem from cartography where we want to color a map in a way that two neighbouring states always have a different color (image 1). ...
