Challenging Benchmarks for Diagrammatic Equivalence of Circuits in TPTP and SMT-LIB

Abstract: We introduce a new family of benchmarks for the problem of diagrammatic equivalence between circuits. Three variants of this problem are considered, ranging from basic to challenging, and benchmarks are generated for each variant. We provide first-order encodings in both TPTP and SMT-LIB formats, together with scripts that automatically generate benchmark instances, and evaluate these benchmarks on state-of-the-art automated theorem provers and SMT solvers.
