Properties of objective functions and search algorithms in multi-objective optimization problems

open access: yesРоссийский технологический журнал, 2022
Objectives. A frequently used method for obtaining Pareto-optimal solutions is to minimize a selected quality index under restrictions of the other quality indices, whose values are thus preset.

SELVa: Simulator of evolution with landscape variation.

open access: yesPLoS ONE, 2020
Organisms evolve to increase their fitness, a process that may be described as climbing the fitness landscape. However, the fitness landscape of an individual site, i.e., the vector of fitness values corresponding to different variants at this site, can ...

Fitness of Nutrition Regulation in a Caterpillar Pest Mythimna separata (Walker): Insights from the Geometric Framework

open access: yesInsects, 2023
In nature, plants can contain variable nutrients depending upon the species, tissue, and developmental stage. Insect herbivores may regulate their nutrient intake behaviorally and physio- logically when encountering different foods.

Simulation-based fitness landscape analysis and optimisation of complex problems

open access: yesTechnological and Economic Development of Economy, 2015
Widespread hard optimisation problems in economics and logistics are characterised by large dimensions, uncertainty and nonlinearity and require more powerful methods of stochastic optimisation that traditional ones. Simulation optimisation is a powerful

A Fitness Landscape Analysis for the No-Wait Flow Shop Scheduling Problem With Factorial Representation

open access: yesIEEE Access, 2019
The no-wait flow shop scheduling problem (NWFSP) is one of the essential models in the manufacturing systems. In this paper, the fitness landscape of the factorial representation for NWFSP with the makespan criterion is studied. The encoding and decoding

Quantifying the Evolutionary Constraints and Potential of Hepatitis C Virus NS5A Protein

open access: yesmSystems, 2021
RNA viruses, such as hepatitis C virus (HCV), influenza virus, and SARS-CoV-2, are notorious for their ability to evolve rapidly under selection in novel environments.

On the incongruence of genotype-phenotype and fitness landscapes.

open access: yesPLoS Computational Biology, 2022
The mapping from genotype to phenotype to fitness typically involves multiple nonlinearities that can transform the effects of mutations. For example, mutations may contribute additively to a phenotype, but their effects on fitness may combine non ...
