10.2 Submodular Functions, Part II

Показать описание
In this lecture we give the basic greedy algorithm, and give the proof by Wolsey, Nemhauser and Fisher stating that if \mathcal{I} is the uniform matroid, and f is a monotone submodular function, then the Greedy algorithm is within a (1-1/e) factor of optimal.

Hi Constantine, thanks for the great video! Could you also explain why 1-1/e is tight for maximizing submodular fucntion under uniform constraint?
