Greedy optimization
Webconvex optimization methods are developed and analyzed as more efficient alternatives (see, e.g., Beck and Teboulle, 2009; Agarwal et al., 2010). Another category of low-complexity algorithms in CS are the non-convex greedy pursuits including Orthogonal Matching Pursuit (OMP) (Pati et al.,
