Special Issue Information

Dear Colleagues,

Dynamical systems and differential equations (DEs) form the backbone of modeling across various fields, including physics, engineering, biology, and finance. The analysis and simulation of such models require efficient algorithms that can handle high-dimensional complexity, nonlinearity, stochasticity, and chaotic behavior. Recent advances in algorithmic design, numerical analysis, and hybrid analytical–computational methods have opened new possibilities for understanding and solving challenging problems in this domain.

In this Special Issue, we aim to bring together high-quality contributions at the interface of algorithm development and dynamical system analysis. We invite researchers to present original research and reviews on novel algorithms, theoretical frameworks, and computational strategies that advance the study of nonlinear dynamical systems, DEs, and their wide-ranging applications.

We particularly encourage works that bridge analytical insights with algorithmic innovation, highlighting efficiency, robustness, and applicability to real-world problems.

Topics of Interest (but not limited to):

  • Algorithmic approaches for solving nonlinear DEs;
  • Analytical–computational hybrid methods for soliton theory, wave propagation, and pattern formation;
  • Algorithms for bifurcation analysis, chaos detection, and stability in complex systems;
  • Machine learning and data-driven algorithms for DEs and dynamical systems;
  • Approximation algorithms for stochastic, fractional, and time-delay systems;
  • High-performance computing algorithms for large-scale DE simulations;
  • Algorithmic complexity and optimization in dynamical systems modeling;
  • Iterative and optimization algorithms for eigenvalue problems in DEs and dynamical models.

The geometric content of chaos in nonlinear systems with multiple stabilities of high order is a challenge to computation. We introduce a single algorithmic framework to overcome this difficulty in the present study, where a parametrically forced oscillator with cubic–quintic nonlinearities is considered as an example. The framework starts with the Sparse Identification of Nonlinear Dynamics (SINDy) algorithm, which is a self-learned algorithm that extracts an interpretable and correct model by simply analyzing time-series data. The resulting parsimonious model is well-validated, and besides being highly predictive, it also offers a solid base on which one can conduct further investigations. Based on this tested paradigm, we propose a unified diagnostic pathway that includes bifurcation analysis, computation of the Lyapunov exponent, power spectral analysis, and recurrence mapping to formally describe the dynamical features of the system. The main characteristic of the framework is an effective algorithm of computational basin analysis, which is able to display attractor basins and expose the fine scale riddled structures and fractal structures that are the indicators of extreme sensitivity to initial conditions. The primary contribution of this work is a comprehensive dynamical analysis of the DM-CQDO, revealing the intricate structure of its stability landscape and multi-stability. This integrated workflow identifies the period-doubling cascade as the primary route to chaos and quantifies the stabilizing effects of key system parameters. This study demonstrates a systematic methodology for applying a combination of data-driven discovery and classical analysis to investigate the complex dynamics of parametrically forced, high-order nonlinear systems.
