WebJul 18, 2024 · We prove that any accumulation point of the iterates generated by them is a local minimizer with a desirable bound for the considered sparse group ℓ 0 problem. In particular, all accumulation points have a common support set and their zero entries can be attained within finite iterations.

WebNov 1, 2024 · Optimization problems involving group sparsity terms. This paper studies a general form problem in which a lower bounded continuously differentiable function is minimized over a block separable set incorporating a group sparsity expression as a constraint or a penalty (or both) in the group sparsity setting. This class of problems is … WebIn this paper, a new Sparse Grid-based Optimization Workflow (SpaGrOW) is presented, which accomplishes this task robustly and, at the same time, keeps the number of time-consuming simulations relatively small. This is achieved by an efficient sampling procedure for the approximation based on sparse grids, which is described in full detail: in ... high plains restaurant and bar newell sd
