Vague definition of blocker
The defintion of blocker is poorly defined. B is called a set of edges, but then its written as a subset of vertices. It then says that B intersect with every edge ... but this is the definition of the transversal set of a hypergraph. Perhaps it is meant that every edge in E intersects with some edge in B ??? Or perhaps the blocker is the set of *all* transversals ??? linas (talk) 21:30, 4 May 2008 (UTC)
