Zusammenfassung:Abstract: "This paper concerns algorithms to answer queries in circumscriptive theories. Two recent papers present such algorithms that are relatively complex: Przymusinski's algorithm is based on MILO-resolution, a variant of ordered linear resolution; Ginsberg's theorem prover uses a backward-chaining ATMS. Because of their different concerns, formalisms, and implementation, it is not clear what their relative advantages are. This paper makes a detailed comparison of these relating them to a logical framework of abduction, explains their intuitive meaning, and shows how the efficiency of both can be improved. Additionally, some limitations of both circumscriptive theorem provers are also discussed."
