Random Boolean Networks and Evolutionary Game Theory [PDF]

open access: yes, 2002
Recent years have seen increased interest in the question of whether it is possible to provide an evolutionary game theoretic explanation for certain kinds of social norms. These explanatory approaches often rely on the fact that, in certain evolutionary

The Ecological Root Metaphor for Higher Education: Searching for Evidence of Conceptual Emergence within University Education Strategies

open access: yesEducation Sciences, 2022
Recent research has suggested that Higher Education would benefit from the adoption of institutional models that relinquish ties to industrial thinking and associated metaphors.

On the region of attraction of dynamical systems: Application to Lorenz equations [PDF]

open access: yesArchives of Control Sciences, 2020
Many nonlinear dynamical systems can present a challenge for the stability analysis in particular the estimation of the region of attraction of an equilibrium point. The usual method is based on Lyapunov techniques.

Potentials and limits to basin stability estimation

open access: yesNew Journal of Physics, 2017
Stability assessment methods for dynamical systems have recently been complemented by basin stability and derived measures, i.e. probabilistic statements whether systems remain in a basin of attraction given a distribution of perturbations.

Anatomy of the Attraction Basins: Breaking with the Intuition [PDF]

open access: yesEvolutionary Computation, 2019
Solving combinatorial optimization problems efficiently requires the development of algorithms that consider the specific properties of the problems. In this sense, local search algorithms are designed over a neighborhood structure that partially accounts for these properties.

Newton’s method’s basins of attraction revisited [PDF]

open access: yesApplied Mathematics and Computation, 2009
In this paper, we revisit the chaotic number of iterations needed by Newton's method to converge to a root. Here, we consider a simple modified Newton method depending on a parameter. It is demonstrated using polynomiography that even in the simple algorithm the presence and the position of the convergent regions, i.e.

An Efficient Two-Step Iterative Family Adaptive with Memory for Solving Nonlinear Equations and Their Applications

open access: yesMathematical and Computational Applications, 2022
We propose a new iterative scheme without memory for solving nonlinear equations. The proposed scheme is based on a cubically convergent Hansen–Patrick-type method.

Basins of Attraction of a Nonlinear Nanomechanical Resonator [PDF]

open access: yesPhysical Review Letters, 2007
We present an experiment that systematically probes the basins of attraction of two fixed points of a nonlinear nanomechanical resonator and maps them out with high resolution. We observe a separatrix which progressively alters shape for varying drive strength and changes the relative areas of the two basins of attraction.

Efficient two-step with memory methods and their dynamics. [PDF]

open access: yesMathematics and Computational Sciences
In this work,a fourth-order without-memory method is proposed that has a self-accelerator parameter.This method doesn’t need to compute a derivative function forsolving nonlinear equations.We have approximated the self-accelerator parameter andhave ...
