Research Type Theoretical We propose a minimal reduct for logic programs with c-atoms that yields a new semantic characterization of SPT-answer sets, and then introduce an extension of resolution for clauses with c-atoms. As we show, every atom in an SPT-answer set enjoys an extended resolution proof from the minimal reduct of its logic program. Finally, we present minimal sufficient subsets of logic programs (witnesses) to structure such an extended resolution proof for an atom in an SPT-answer set.

Open Source Code No The paper does not contain any explicit statements about the release of source code for the methodology described, nor does it provide any links to code repositories.
Open Datasets No The paper is theoretical and uses small, illustrative logic programs as examples rather than datasets for empirical evaluation. No datasets are mentioned for public availability.
Dataset Splits No The paper is theoretical and does not perform empirical experiments requiring dataset splits.
Hardware Specification No The paper is theoretical and does not describe experiments. Therefore, no hardware specifications are provided.
Software Dependencies No The paper mentions existing ASP solvers and tools (e.g., clingo, DLV, Disc ASP, s(CASP), xclingo, x ASP) but does not provide specific version numbers as dependencies for reproducing the theoretical work presented.
Experiment Setup No The paper is theoretical and does not describe any experimental setup or hyperparameters.
