The Journal of Nonlinear, Complex and Data Science publishes original papers on all subjects and models relevant to nonlinear sciences, complex and data science, and numerical simulations of these models. The highest priority will be given to those contributions concerned with a discussion of the background of a practical problem, the establishment of an appropriate nonlinear model, the determination of a solution, approximate or exact, analytical or numerical, and a discussion of the relevance of the results when applied to the real-life problem.
