twee: An equational theorem prover

[ bsd3, program, theorem-provers ] [ Propose Tags ]

Twee is an experimental equational theorem prover based on Knuth-Bendix completion.

Given a set of equational axioms and a set of equational conjectures it will try to prove the conjectures. It will terminate if the conjectures are true but normally fail to terminate if they are false.

The input problem should be in TPTP format (see http://www.tptp.org). You can use types and quantifiers, but apart from that the problem must be equational.

Readme for twee-0.1

[back to package description] 
This is twee, a prover for equational problems.

To install, run cabal install.

Afterwards, invoke as twee nameofproblem.p. The problem should be in
TPTP format (http://www.tptp.org). You can find a few examples in the
tests directory. All axioms and conjectures must be equations, but you
can freely use types and quantifiers.

Twee is experimental software, use at your own risk!
