Solving a class of generalized fractional programming problems using the feasibility of linear programs

open access: yesJournal of Inequalities and Applications, 2017
This article presents a new approximation algorithm for globally solving a class of generalized fractional programming problems (P) whose objective functions are defined as an appropriate composition of ratios of affine functions.

A Global Optimization Approach to Quantum Mechanics [PDF]

open access: yesarXiv, 2006
This paper presents a global optimization approach to quantum mechanics, which describes the most fundamental dynamics of the universe. It suggests that the wave-like behavior of (sub)atomic particles could be the critical characteristic of a global optimization method deployed by nature so that (sub)atomic systems can find their ground states ...

Learning to be Global Optimizer

open access: yes, 2020
The advancement of artificial intelligence has cast a new light on the development of optimization algorithm. This paper proposes to learn a two-phase (including a minimization phase and an escaping phase) global optimization algorithm for smooth non-convex functions. For the minimization phase, a model-driven deep learning method is developed to learn

Globally Optimal Cooperation in Dense Cognitive Radio Networks [PDF]

open access: yesarXiv, 2014
The problem of calculating the local and global decision thresholds in hard decisions based cooperative spectrum sensing is well known for its mathematical intractability. Previous work relied on simple suboptimal counting rules for decision fusion in order to avoid the exhaustive numerical search required for obtaining the optimal thresholds. However,

The Informational Approach to Global Optimization in presence of very noisy evaluation results. Application to the optimization of renewable energy integration strategies

open access: yes, 2015
We consider the problem of global optimization of a function f from very noisy evaluations. We adopt a Bayesian sequential approach: evaluation points are chosen so as to reduce the uncertainty about the position of the global optimum of f, as measured ...

Randomized directional search for nonconvex optimization [PDF]

open access: yesarXiv
Direct search methods are a class of popular global optimization algorithms for general nonconvex programs. In this paper, we propose a randomized directional search algorithm (RDSA) for globally solving nonconvex optimization problems. The convergence of RDSA to a global optimizer is established and its computational complexity is derived ...

Multiple sclerosis clinical decision support system based on projection to reference datasets

open access: yesAnnals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 1863-1873, December 2022., 2022
Abstract Objective Multiple sclerosis (MS) is a multifactorial disease with increasingly complicated management. Our objective is to use on‐demand computational power to address the challenges of dynamically managing MS. Methods A phase 3 clinical trial data (NCT00906399) were used to contextualize the medication efficacy of peg‐interferon beta‐1a vs ...
