Preferential entailment

Preferential entailment is a concept in non-monotonic logic and reasoning, which deals with situations where certain conclusions can be drawn based on a set of premises, but these conclusions may not hold if additional information is added. It contrasts with classical logic, where the conclusions drawn from a set of premises are considered definitive and immutable. In preferential entailment, the idea is that certain models or interpretations of the knowledge may be preferred over others based on specific criteria.
