This directory contains ML sources of generic theorem proving tools.
Typically, they can be applied to various logics, provided rules of a
certain form are derivable.
blast.ML generic tableau prover with proof reconstruction
clasimp.ML combination of classical reasoner and simplifier
classical.ML theorem prover for classical logics
hypsubst.ML tactic to substitute in the hypotheses
quantifier1.ML simplification procedures for "1 point rules"
splitter.ML performs case splits for simplifier
typedsimp.ML basic simplifier for explicitly typed logics
directory Arith:
assoc_fold.ML fold numerals in nested products
cancel_numerals.ML cancel common coefficients in balanced expressions
cancel_sums.ML cancel common summands
combine_numerals.ML combine coefficients in expressions
