Abstract

This paper presents a proof demonstrating that the Cubic Monotone 1-in-3 SAT Problem, which is a variant of the Boolean Satisfiability Problem (SAT), can be solved in polynomial time. The proof focuses on establishing that this problem is polynomial time reducible to the Maximum Independent Set Problem in a bounded treewidth graph. While further verification is required to validate the correctness of the proof, this claim represents a potential breakthrough in one of the most significant open problems in computer science and mathematics. 

Keywords
