Requirements of representation of incomplete, evolutive and conflicting knowledge led to a rise of alternative logic formalisms, dubbed nonmonotonic logics. Important features of nonmonotonic logic were discussed on the example of default logic – a role of assumptions in reasoning, use of fixpoint constructions as a formal tool for building a nonmonotonic semantics and, finally, computational aspects of nonmonotonic reasoning. This overview is completed by a presentation of our approach to updates. Updates are closely connected to nonmonotonic reasoning. We construct our approach for assumption based frameworks (and for default theories, as a consequence).</style></abstract><custom3><style face="normal" font="default" size="100%">216234</style></custom3><custom5><style face="normal" font="default" size="100%">1</style></custom5></record></records></xml>
