WebTheory #. Matroids are combinatorial structures that capture the abstract properties of (linear/algebraic/…) dependence. Formally, a matroid is a pair M = ( E, I) of a finite set E, the groundset, and a collection of subsets I, the independent sets, subject to the following axioms: I contains the empty set. If X is a set in I, then each ... WebJack R. Edmonds (born April 5, 1934) is an American-born and educated computer scientist and mathematician who lived and worked in Canada for much of his life.
