The Satisfiability Modulo Theories Competition (SMT-COMP) is intended to spark further advances in the decision procedures field, especially for applications in hardware and software verification. Public competitions are a well-known means of stimulating advancement in automated reasoning. Evaluation of SMT solvers entered in SMT-COMP took place while CAV 2005 was meeting. Twelve solvers were entered, 1352 benchmarks were collected in seven different divisions.
