Web3 The greedy algorithm The greedy algorithm (henceforth referred to as Greedy) is a natural heuristic for maximizing a monotone submodular function subject to certain constraints. In several settings it provides good approximation ratios, and until quite recently, the approximation ratios provided by Greedy were the best known in most cases.
