‐quotient. We extend this result in two ways. First, we apply the greedy algorithm to an inner independence system contained in ℐ …‐quotient that yields a tight bound on the worst‐case performance of the greedy algorithm applied to the inner independence system … approximation may outperform not only the standard greedy algorithm but also the inner matroid approximation proposed by Milgrom …
