CLTSA: A Novel Tunicate Swarm Algorithm Based on Chaotic-Lévy Flight Strategy for Solving Optimization Problems

open access: yesMathematics, 2022
In this paper, we proposed a tunicate swarm algorithm based on Tent-Lévy flight (TLTSA) to avoid converging prematurely or failing to escape from a local optimal solution.

Periodic Patterns of Signed Shifts [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2013
The periodic patterns of a map are the permutations realized by the relative order of the points in its periodic orbits. We give a combinatorial description of the periodic patterns of an arbitrary signed shift, in terms of the structure of the descent ...

Spectral decomposition of the tent map with varying height [PDF]

open access: yesChaos: An Interdisciplinary Journal of Nonlinear Science, 1998
The generalized spectral decomposition of the Frobenius–Perron operator of the tent map with varying height is determined at the band-splitting points. The decomposition includes both decay onto the attracting set and the approach to the asymptotically periodic state on the attractor.

Search for invariant sets of the generalized tent map

open access: yesJournal of Difference Equations and Applications, 2022
This paper describes a predictive control method to search for unstable periodic orbits of the generalized tent map. The invariant set containing periodic orbits is a repelling set with a complicated Cantor-like structure. Therefore, a simple local stabilization of the orbit may not be enough to find a periodic orbit, due to the small measure of the ...

Adaptive Color Image Encryption Scheme Based on Multiple Distinct Chaotic Maps and DNA Computing

open access: yesMathematics, 2022
In this paper, we propose an adaptive encryption scheme for color images using Multiple Distinct Chaotic Maps (MDCM) and DNA computing. We have chosen three distinct chaotic maps, including a 2D-Henon map, a Tent map, and a Logistic map, to separately ...
