The four color theorem is one of the most well-known and remarkable results in graph theory. This theorem
establishes that any geographic map on a plane can be colored with only 4 colors in such a way that no
adjacent regions have the same color.
This problem was first posed in the 19th century, although it could only be proven in 1976 using computational methods.
This theorem has found applications in various fields, such as cartography, scheduling and resource
allocation. In summary, it is a surprising result that makes it one of the most recognized and exciting
achievements in the history of mathematics.
