A general approach to bottom-up computation of disjunctive semantics,or the remaining literals, we propose to use an appropriate completion of the residual program, which syntactically characterizes the intended models. In the case of the stable model semantics, we utilize an interesting connection to .‘s completion.

From disjunctive programs to abduction,l negation and epistemic disjunction are used in the first of these approaches, abductive logic programs with classical negation in the second, and a simpler form of abductive logic programming — without classical negation — in the third. In the literature, these ideas have been illustrated with exa

Static semantics as program transformation and well-founded computation,ed semantics for normal programs. Based on considerations about how disjunctive information is treated by a given semantics, we divide the computation of that semantics into two phases. The first one is a program transformation phase, which applies axiom schemata expressing how derivations involving

Magic computation for well-founded semantics,we introduce a new magic templates transformation and give a new fixed point characterization of the well-founded semantics, lifting an existing definition from the ground to the non-ground case. The new fixed point characterization enables us to show a step-by-step correspondence between the naive
