Reiter's Default Logic

Reiter's Default Logic is a framework for reasoning in situations where we have incomplete information. It allows us to make assumptions (called "defaults") when there's no clear evidence, helping us fill in gaps in our knowledge. For instance, if we know that birds typically fly, we might assume a new bird can fly unless we find evidence that it can't, like being a penguin. This approach helps in creating logical conclusions from general knowledge, handling exceptions, and updating beliefs when new information arises, thus making our reasoning more flexible and realistic.
