The Four Color Problem
The Four Color Problem is a problem in mathematics that asks if it is possible to color a map with only four colors, so that no two adjacent regions have the same color. The Four Color Theorem was proven in 1976 by Kenneth Appel and Wolfgang Haken using a computer program. The theorem has been proven to be correct, although the proof has never been accepted by some mathematicians.

four color problem
Four Color Problem: This problem seeks to determine the minimum number of colors needed to color any given map so that no two adjacent regions have the same color.
Graph Theory: This is the branch of mathematics that studies the properties of graphs and their applications in various fields.
Coloring Problem: This is a problem in which a set of objects must be colored using only a set number of colors such that no two adjacent objects have the same color.

Did you know?
The four color theorem was first proposed in 1852 by Francis Guthrie, a college student at University College London. It was the first major theorem to be proven with the help of a computer in 1976. The four color theorem can also be applied to maps of the moon and other planets.
