Fireworks explosion boosted Harris Hawks optimization for numerical optimization: Case of classifying the severity of COVID-19 [PDF]

open access: yesFrontiers in Neuroinformatics, 2023
Harris Hawks optimization (HHO) is a swarm optimization approach capable of handling a broad range of optimization problems. HHO, on the other hand, is commonly plagued by inadequate exploitation and a sluggish rate of convergence for certain numerical ...

Optimization Procedure and Toolchain for Roll Dynamic Geometry

open access: yesMachines, 2022
In rolls manufactured from first bent and then welded sheets of steel, the asymmetric distribution of mass due to the weld seam as well as imperfections of the geometry due to the bending may cause the roll cross-section roundness profiles to deform due ...

Optimized Balance Between Electricity Load and Wind-Solar Energy Production

open access: yesFrontiers in Energy Research, 2020
One of the greatest obstacles in the exploitation of wind and solar resources is the uncertainty in their availability, usually known as intermittence. These effects can be greatly diminished by combining wind and solar resources from different locations.

Optimal Numerical Integration [PDF]

open access: yesCybernetics and Computer Technologies, 2020
Introduction. In many applied problems, such as statistical data processing, digital filtering, computed tomography, pattern recognition, and many others, there is a need for numerical integration, moreover, with a given (often quite high) accuracy. Classical quadrature formulas cannot always provide the required accuracy, since, as a rule, they do not

A maximum likelihood model for fitting power functions with data uncertainty: A case study on the relationship between body lengths and masses for Sciuridae species worldwide

open access: yesJournal of Asia-Pacific Biodiversity, 2016
In this report, a maximum likelihood model is developed to incorporate data uncertainty in response and explanatory variables when fitting power-law bivariate relationships in ecology and evolution. This simple likelihood model is applied to an empirical

Regularized Nonlinear Acceleration [PDF]

open access: yes, 2018
We describe a convergence acceleration technique for unconstrained optimization problems. Our scheme computes estimates of the optimum from a nonlinear average of the iterates produced by any optimization method.
