Circumscription - A Form of Nonmonotonic Reasoning

This paper was published in Artificial Intelligence in 1980.

Circumscription - A Form of Nonmonotonic Reasoning was published in Artificial Intelligence in 1980. The present version has an addendum that was not in the published paper.

The formalism of this paper is substantially superseded by that of Applications of circumscription to formalizing common sense published in 1986. In particular the latter paper properly treats variables that are not minimized. References in the literature to this paper only would better refer to the latter paper in addition or to the latter paper only.
