Relative greedy weights were introduced by Li and Liu in [19] as a measure of information leakage in coordinated two-party wire-tap channels of type II when the adversary follows a greedy strategy. Their definition can be viewed as a relative version of the CEZ greedy weights, which are only locally greedy. In this paper, we revisit the concept of greediness and relative greediness introducing new measures, and we discuss other perhaps more relevant applications of relative greedy weights than the coordinated two-party wire-tap channel of type II. We pay special attention to bottom-up greedy weights, which correspond to an adversary with an ultimate greedy approach, and we present families of nested codes for which such weights are larger than the relative CEZ greedy weights.
