An Adaptive Mechanism With Cooperative Coevolution and Covariance for Differential Evolution

open access: yesIEEE Access, 2021
Differential evolution (DE) is an evolutionary algorithm widely used to solve optimization problems with different characteristics in fields where actions and decisions depend on numerical data such as engineering, economics, and logistics. In this paper,

Identifying Market Price Levels Using Differential Evolution [PDF]

open access: yes, 2013
Evolutionary data mining is used in this paper to investigate the concept of support and resistance levels in financial markets. Specifically, Differential Evolution is used to learn support/resistance levels from price data. The presence of these levels

ON THE EVOLUTION OF DIFFERENTIATED MULTICELLULARITY [PDF]

open access: yesEvolution, 2009
Most conspicuous organisms are multicellular and most multicellular organisms develop somatic cells to perform specific, non-reproductive tasks. The ubiquity of this division of labor suggests that it is highly advantageous. In this paper, I present a model to study the evolution of specialized cells.

Limited Evaluation Cooperative Co-evolutionary Differential Evolution for Large-scale Neuroevolution [PDF]

open access: yes, 2018
Many real-world control and classification tasks involve a large number of features. When artificial neural networks (ANNs) are used for modeling these tasks, the network architectures tend to be large.

Classification of Gene Expression Data Using Multiobjective Differential Evolution

open access: yesEnergies, 2016
Gene expression data are usually redundant, and only a subset of them presents distinct profiles for different classes of samples. Thus, selecting high discriminative genes from gene expression data has become increasingly interesting in bioinformatics ...

Differential Evolution between Monotocous and Polytocous Species [PDF]

open access: yesAsian-Australasian Journal of Animal Sciences, 2014
One of the most important traits for both animal science and livestock production is the number of offspring for a species. This study was performed to identify differentially evolved genes and their distinct functions that influence the number of ...
