Abstract

We show that the classical Ramsey number \(R(3,3,3,3)\) is no greater than \(62\). That is, any edge coloring with four colors of a complete graph on \(62\) vertices must contain a monochromatic triangle. Basic notions and a historical overview are given along with the theoretical framework underlying the main result. The algorithms for the computational verification of the result are presented along with a brief discussion of the software tools that were utilized.
