We extend the well-founded semantics of Van Gelder et al. [12] so that it is able to reason through clauses instead of single literals. This is necessary to infer p to be true in the program {p ← a; p ← b; a ← ¬b; b ← ¬a}. We call this generalized semantics, the generalized well-founded semantics. We present fixpoint and model theoretic definitions for generalized well-founded semantics and show their equivalence.
