Bloques y antibloques de agregación y diferencia de clutters

Abstract

In this paper, we analize four problems: - Given two clutters, such that the union is a clutter, to find the blocking of the union when we know the blocking of every clutter. - Given two clutters, such that the union is a clutter, to find the antiblocking of the union when we know the antiblocking of every clutter. - Given a clutter with known blocking, to find the blocking of a subset. - Given a clutter with known antiblocking, to find the antiblocking of a subset.
