Abstract

We present derivation proof procedures for extended stable model semantics. Given program II and goal G, G belongs to the well founded model of II iff there is a W F M-derivation for Gin II. Likewise, given program II and goal G, G belongs to some extended stable model of II iff there is a XSM-derivation for Gin II. Correctness (completeness and soundness) of these procedures is discussed. Example derivations are exhibited, as well as a simple Prolog implementation that directly mirrors the procedures.
