Generating Difficult SAT Instances by Preventing Triangles

8 Mar 2019Guillaume EscamocherBarry O'SullivanSteven David Prestwich

When creating benchmarks for SAT solvers, we need SAT instances that are easy to build but hard to solve. A recent development in the search for such methods has led to the Balanced SAT algorithm, which can create k-SAT instances with m clauses of high difficulty, for arbitrary k and m. In this paper we introduce the No-Triangle SAT algorithm, a SAT instance generator based on the cluster coefficient graph statistic... (read more)
