Greedy strategies for convex optimization
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. WebMay 14, 2015 · Abstract: We suggest a new greedy strategy for convex optimization in Banach spaces and prove its convergent rates under a suitable behavior of the modulus of uniform smoothness of the objective function.

WebThis paper discusses a data-driven, cooperative control strategy to maximize wind farm power production. Conventionally, every wind turbine in a wind farm is operated to maximize its own power production without taking into account the interactions between the wind turbines in a wind farm. Because of wake interference, such greedy control strategy can … WebAn icon used to represent a menu that can be toggled by interacting with this icon.

Our iterative method is based on a two-level strategy. At the outer level, we construct a sequence of ℓ0-constrained second-order Taylor expansions of the problem; at the in-ner level, an iterative hard-thresholding algorithm is used
