Dung's semantics satisfy attack removal monotonicity

Artificial Intelligence 2020-07-09 v1

Abstract

We show that preferred, stable, complete, and grounded semantics satisfy attack removal monotonicity. This means that if an attack from b to a is removed, the status of a cannot worsen, e.g. if a was skeptically accepted, it cannot become rejected.
