* Implemented a HOL specific finite model, which knows about numbers, lists and sets. * Removed multiple provers: METIS_TAC is now solely based on ordered resolution.

Latest version of METIS_TAC. The biggest change is that scheduling provers is done by number of inferences, not time used, so METIS_TAC is now completely deterministic. If it works for you on a subgoal, it will work every time HOL4 is built.

Version 1.3: 17 June 2002 Goals submitted to MESON_TAC when HOL is built .......... 1953 Proved by MESON_TAC ..................................... 1953 Proved by METIS_TAC within 10s .......................... 1946 Between Versions 1.2 and 1.3 * Implemention of definitional CNF to reduce blow-up in number of clauses (usually caused by nested boolean equivalences). * Resolution is more robust and efficient, and includes an option (off by default) for clauses to inherit ordering constraints.
