Frontiers in Complex Systems is a multidisciplinary open-access journal at the forefront of disseminating and communicating scientific knowledge and impactful discoveries in High Performance Computing research to a broad community of researchers, academics, clinicians, and other relevant stakeholders.

Frontiers in Complex Systems covers fundamental questions, theories and general methodologies on complex systems as well as the cross-disciplinary application of these concepts and methods, often giving rise to new disciplines. It provides a forum for cross-disciplinary communication and welcomes quantitative research from different fields including Physics, Mathematics, Computer Sciences, Artificial Intelligence, Engineering, Climate change, Economics and Finance, Social Sciences, Linguistics, Ecology, Neuroscience, Health Sciences, Epidemics, Mobility and Transport, City Science, etc.

Frontiers in Complex Systems is dedicated to advancing developments in the field of high-performance computing by providing unrestricted access to articles and communicating scientific knowledge to researchers and the public, enabling future scientific breakthroughs.

This Research Topic is dedicated to collecting forward-looking articles composed by the Chief Editors of the journal. These contributions will identify and reflect upon what could be dubbed the “grand challenges” in Complex Systems research in the following specialties:

- Complex Networks: Explores complex networks research, covering structure, dynamics, and functions of interconnected systems across biology, technology, and social science

- Complex Systems Theory: Explores research on complex systems theory, covering foundational research on emergence, adaptation, chaos and modeling of intricate systems across disciplines.

- Control and Engineering of Complex Systems: Explores research on control and engineering of complex systems, covering modeling, optimization and adaptive control in networked, nonlinear and large-scale systems.

- Multi- and Cross-Disciplinary Complexity: Explores multi- and cross-disciplinary complexity research, covering complex phenomena spanning physics, biology, economics and social systems.
