Interdisciplinary studies on complex systems have gained extensive research interests. Significant impacts have been made by such studies in a wide range of different areas including physics, biology, economics, social sciences, computer sciences, electrical, mechanical and civil engineering, etc. In the long-term future, the way we understand and cope with the world may all be revolutionized.

This journal aims to reflect the interdisciplinary features of the exciting studies on complex systems. The scope include, but are not limited to, complex networks, complex social and economic systems, complex biological systems, complex engineering systems, complex system methods, and general complexity sciences, etc.

On a peer-review basis, we publish full papers, letters, surveys, as well as essays. We welcome quick work-in-progress reports on preliminary research results with novelty. We also welcome comprehensive reports on finished projects. Innovative ideas and more insights into complex systems and their applications are what we are looking for. You are cordially welcome to join us to make this journal a success.

The scope of the journal includes, but is not limited to:

• Complex networks
• Complex social systems
• Complex economic systems
• Complex biological systems
• Complex engineering systems
• Complex system modelling
• Complex system simulation
• Complex system theories
• Complex systems of complex systems
• Complexity in arts and music
• General complexity sciences
• New frontiers of complex systems
