TLDR
E is a sound and complete prover for clausal first order logic with equality and has a very flexible interface for specifying search control heuristics, and an efficient inference engine.
Abstract
We describe the superposition-based theorem prover E. E is a sound and complete prover for clausal first order logic with equality. Important properties of the prover include strong redundancy elimination criteria, the DISCOUNT loop proof procedure, a very flexible interface for specifying search control heuristics, and an efficient inference engine. We also discuss strength and weaknesses of the system.

Rewrite-based Equational Theorem Proving with Selection and Simplification

TL;DR: This paper forms an abstract notion of redundancy and shows that the deletion of redundant clauses during the theorem proving process preserves refutation completeness, and presents various refutationally complete calculi for first-order clauses with equality that allow for arbitrary selection of negative atoms in clauses.
