WebApr 1, 2024 · In simple terms, graph coloring means assigning colors to the vertices of a graph so that none of the adjacent vertices share the same hue. And, of course, we want to do this using as few colors as possible. Imagine Australia, with its eight distinct regions (a.k.a. states). Map Australia Regions. Let’s turn this map into a graph, where each ... WebNov 1, 2024 · As indicated in Section 1.2, the map coloring problem can be turned into a graph coloring problem.

WebMay 30, 2014 · Map coloring, where one colors the countries on a map in such a way that adjacent countries get different colors, is of course closely related to graph coloring. The girls made their own maps to challenge each other, and then undertook to color those maps. We discussed the remarkable fact that four colors suffice to color any map.
