Researchers have refined the Gelfond Rationality Principle to develop more comprehensive foundational principles for answer set semantics in non-monotonic logic programming. The study questions the mandatory nature of minimal model property, constraint monotonicity, and foundedness, suggesting they may be too restrictive. New principles of well-supportedness, minimality with respect to negation by default, and minimality with respect to epistemic negation are proposed to ensure answer sets are constructible and minimize knowledge.
