Abstract

A common proof format for solvers for Satisfiability Modulo Theories (SMT) is proposed, based on the Edinburgh Logical Framework (LF). Two problems arise: checking very large proofs, and keeping proofs compact in the presence of complex side conditions on rules. Incremental checking combines parsing and proof checking in a single step, to avoid building in-memory representations of proof subterms. LF with Side Conditions (LFSC) extends LF to allow side conditions to be expressed using a simple first-order functional programming language. Experimental data with an implementation show very good proof checking times and memory usage on benchmarks including the important example of resolution inferences. © 2008 Elsevier B.V.
