Nonmonotonic and Inductive Logic

This proceedings volume contains a selection of revised andextended papers presented at the Second InternationalWorkshop on Nonmonotonic and InductiveLogic, NIL '91, whichtook place at Reinhardsbrunn Castle, December 2-6, 1991. The volume opens with an extended version of a tutorial onnonmonotonic logic by G. Brewka, J. Dix, and K. Konolige. Fifteen selected papers follow, on a variety of topics. Themajority of papers belong either to the area of nonmonotonicreasoning or to the field of inductive inference, butsome papers integrate research from both areas. The first workshop in this series was held at the Universityof Karlsruhe in December 1990 and its proceedings werepublished as Lecture Notes in Artificial Intelligence Volume543. The series of workshops was made possible by financialsupport from Volkswagen Stiftung, Hannover. This workshopwas also supported by IBM Deutschland GmbH and Siemens AG.
