It +accepts a problem specification, typically consisting of a number of +first-order clauses or formulas, and a conjecture, again either in +clausal or full first-order form. The system will then try to find a +formal proof for the conjecture, assuming the axioms. + +If a proof is found, the system can provide a detailed list of proof +steps that can be individually verified. If the conjecture is +existential (i.e. it’s of the form “there exists an X with property +P”), the latest versions can also provide possible answers (values for +X). + +Development of E started as part of the E-SETHEO project at TUM. The +first public release was in in 1998, and the system has been +continuously improved ever since. I believe that E now is one of the +most powerful and friendly reasoning systems for first-order +logic. The prover has successfully participated in many competitions. +</longdescription> +<use> + <flag name='isabelle'>Add integration support for the Isabelle/HOL + theorem prover.</flag> +</use> +</pkgmetadata> |
