nonmonotonic logic

a mathematical reasoning system in which information previously considered correct can be revised and removed in the light of new information. This means that any other information believed to be correct on the basis of the removed information must also be reconsidered. The system is said to be “nonmonotonic” because information considered correct does not remain the same or grow larger with further reasoning. These nonmonotonic systems are often controlled by “belief revision” or “truth maintenance” algorithms.
