Out of the Niche: Using Direct Search Methods to Find Multiple Global Optima

open access: yesMathematics, 2022
Multimodal optimization deals with problems where multiple feasible global solutions coexist. Despite sharing a common objective function value, some global optima may be preferred to others for various reasons.

Genetic Algorithms as Computational Methods for Finite-Dimensional Optimization

open access: yesКібернетика та комп'ютерні технології, 2021
Introduction. As early as 1744, the great Leonhard Euler noted that nothing at all took place in the universe in which some rule of maximum or minimum did not appear [12].

Comparing variable neighbourhood search algorithms for the direct aperture optimisation in radiotherapy [PDF]

open access: yesPeerJ Computer Science
Intensity modulated radiation therapy (IMRT) is a prevalent approach for administering radiation therapy in cancer treatment. The primary objective of IMRT is to devise a treatment strategy that eradicates cancer cells from the tumour while minimising ...
