Stephan Schulz: "System Abstract: E 0.3" Abstract: We describe the main characteristics of version 0.3 of the E equational theorem prover. E is based on superposition and rewriting. It features a powerful interface for specifying search guiding heuristics. We discuss some important details of the implementation and demonstrate the performance of the prover by presenting experimental results on the TPTP. Finally, we describe our future plans for improving the system.
