Web3.1 Greedy Algorithms We study simple vertex-based greedy algorithms. It is folklore that a deterministic vertex-based greedy algorithm (cf. Alg.1) for ver-tex cover only achieves a Θ(logn)-approximation. As our aim is understanding how randomization can help the greedy algorithm. For this, we consider a randomized (vertex-based) greedy algo ...
