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 ... WebMay 22, 2024 · Optimization algorithms (in the case of minimization) have one of the following goals: Find the global minimum of the objective function. This is feasible if the objective function is convex, i.e. any local minimum is a global minimum. Find the lowest possible value of the objective function within its neighborhood.

Introduction Our work here addresses general constrained convex optimization problems of the form min x ! D f (x ) . (1) We assume that the objective function f is ... WebJan 20, 2024 · Submodularity, a discrete analog of convexity, is a key property in discrete optimization that features in the construction of valid inequalities and analysis of the greedy algorithm. In this paper, we broaden the approximate submodularity literature, which so far has largely focused on variants of greedy algorithms and iterative approaches.
