Webminimum of E is attained in the convex hull of D, since the approximant xm is derived as a convex combination of xm−1 and ϕm. In this paper, we introduce a new greedy algorithm based on one dimen-sional optimization at each step, which does not require the solution of (1.1) to belong to the convex hull of D and has a rate of convergence O(m1 ... WebWe point out that all convex optimization problems over convex hulls of atomic sets (Chandrasekaran et al.,2012), which appear as the natural convex re-laxations of combinatorial (NP-hard) \sparsity" prob-lems, are directly suitable for Frank-Wolfe-type meth-ods (using one atom per iteration), even when the do-main can only be approximated.
