Abstract: This letter addresses precise control of multifocus (MF) power distribution problems in near-field focusing (NFF) planar arrays based on convex optimization. First, a single focal point (FP) ...

Primal-dual methods in online optimization give several of the state-of-the art results in both of the most common models: adversarial and stochastic/random order. Here we try to provide a more ...

Optimization problems often involve situations in which the user's goal is to minimize and/or maximize not a single objective function, but several, usually conflicting, functions simultaneously. Such ...

Abstract: In this article, the classic portfolio selection problem is reformulated as nine convex optimization problems to maximize nine risk-adjusted performance indexes based on nine different risk ...
