Abstract | The issue of the preservation of equivalences between stratified logic programs under updates is addressed, using several different semantics of equivalence, including equivalence of stable models, subsumption equivalence and logical equivalence with respect to Clark's completion. Each definition of equivalence is tested against 5 different update semantics. Generalizations are then drawn where possible to determine an update semantics which tends to promote equivalence preservation. Finally, conditions are given which, if holding true for two programs, ensures those programs' continued equivalence under updates. |
