The investigation of complex systems in a unified manner is recognized during the last few years as a new and very promising scientific discipline. Therefore, a wide range of interdisciplinary methods and techniques should be applied and, at the same time, new tools should be invented to extract hidden and valuable information from the dynamics of complex systems.

The main aim of this special issue is to present algorithms and modelling techniques for analysing complex phenomena and dynamical systems with nonlinear and memory effects.

Fractional calculus, in view of its practical applications in several disciplines such as physics and engineering problems, is found to be capable of describing phenomena possessing long range memory effects that are difficult to handle with classical integer-order calculus. There has been a growing interest in the adaptation of fractional calculus as an effective modeling tool for complex systems, giving rise to new perspectives in their dynamical analysis and control. This development in the scientific knowledge is demonstrated by a large number of books and events emerging on the topic during the past years. However, many phenomena still pose considerable challenges to the concerned community and fractional calculus seems to be the probable candidate to encompass broader paradigms by shedding light into the description of complexity.

This special issue contains the papers addressing the recent theoretical advances and experimental results on the topics such as chaos, fractals, fractional dynamics, impulsive and neural systems, information and computation theory, signal processing (filtering, restoration, reconstruction, and analysis of fractal noise), image encryption and hiding, mechanics, Navier-Stokes equations on Cantor sets, mechatronics (viscoelasticity, vibration insulation, and control), biology (orthodontic root resorption, classifications of some structural domains of proteins, and genetic algorithms), biophysics (signal and models of biological systems, control of language of competitive models, tourism systems, and viscoelasticity in biology), bioengineering, nanotechnology, anomalous diffusion, and complex adaptive systems.

The Guest Editors believe that the set of selected advanced studies offer readers a timely update of important research topics and may serve as a platform for motivating further contributions in this fast evolving arena.
