non-monotonic modal logic

Non-monotonic modal logic is a type of logical system that models reasoning where conclusions can change as new information arrives, unlike traditional logic where once something is deduced, it stays true. It combines modal logic, which deals with possibility and necessity, with non-monotonic reasoning, allowing for flexibility and updates in knowledge. This is useful for capturing real-world reasoning, where beliefs are revised when new evidence appears, such as in AI or knowledge representation, reflecting more human-like decision-making that adapts over time.
