Package E

Equational Theorem Prover

E is a purely equational theorem prover for full first-order logic.
That means it is a program that you can stuff a mathematical
specification (in first-order format) and a hypothesis into, and which
will then run forever, using up all of your machines' resources. Very
occasionally it will find a proof for the hypothesis and tell you so.

E's inference core is based on a modified version of the superposition
calculus for equational clausal logic. Both clausification and
reasoning on the clausal form can be documented in checkable proof

E was the best-performing open source software prover in the 2008 CADE
ATP System Competition (CASC) in the FOF, CNF, and UEQ divisions. In
the 2011 competition, it won second place in the FOF division, and
placed highly in CNF and UEQ.
