WebbWe deﬁne the Pure Greedy Algorithm (PGA). We describe this algorithm for a general dictionary D. If f ∈ H, we let g(f) ∈ D be an element from D which maximizes hf,gi. We assume for simplicity that such a maximizer ex-ists; if not suitable modiﬁcations are necessary (see Weak Greedy Algorithm below) in the algorithm that follows. We deﬁne Webbtic algorithms for the problems Max d-Clique and Max d-Club. First we propose simple heuristic algorithms for Max d-Clique and Max d-Club, respectively in Sections 4.1 and 4.2, based on the following simple observa-tion. Then, Section 4.3 gives a heuristic algorithm for Max d-Clique based on a heuristic algorithm for Max Clique proposed in [29].
