Abstract

A filter oracle for a clutter consists of a finite set V and an oracle which, given any set X ⊆ V , decides in unit time whether X contains a member of the clutter. Let A2n be an algorithm that, given any clutter C over 2n elements via a filter oracle, decides whether C is ideal. We prove that in the worst case, A2n makes at least 2n−1 calls to the filter oracle. Our proof uses the theory of cuboids.
