An inflationary differential evolution algorithm for space trajectory optimization [PDF]

open access: yes, 2011
In this paper we define a discrete dynamical system that governs the evolution of a population of agents. From the dynamical system, a variant of Differential Evolution is derived.

Geometric differential evolution [PDF]

open access: yesProceedings of the 11th Annual conference on Genetic and evolutionary computation, 2009
Geometric Particle Swarm Optimization (GPSO) is a recently introduced formal generalization of traditional Particle Swarm Optimization (PSO) that applies naturally to both continuous and combinatorial spaces. Differential Evolution (DE) is similar to PSO but it uses different equations governing the motion of the particles.

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,

A hybridizing-enhanced differential evolution for optimization [PDF]

open access: yesPeerJ Computer Science, 2023
Differential evolution (DE) belongs to the most usable optimization algorithms, presented in many improved and modern versions in recent years. Generally, the low convergence rate is the main drawback of the DE algorithm.

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.
