Complex Systems

About Complex Systems

Complex Systems was founded by Stephen Wolfram in 1987 as part of his work in launching the field of complex systems research.

As the first journal in the field, Complex Systems has had the privilege of publishing many seminal papers over the course of three decades.

Complex Systems journal has developed a uniquely broad base of readers and contributors from academia, industry, government and the general public in over 50 countries around the world. The topics of research covered by Complex Systems span a diverse array of areas, including mathematics, physics, computer science and biology.

Read the Nature article by Sir John Maddox, in which he introduced Complex Systems to Nature's readership in 1987.

Complex Systems Open Access Terms
Complex Systems is Platinum Open Access. This means permanent and free access to published scientific works for readers with no publication fees for the authors—100% free. All articles are published under the most flexible reuse standard—the CC BY license (

The original journal devoted to the science, mathematics and engineering of systems with simple components but complex overall behavior; publishes high-quality articles that focus on, but are not limited to, the following areas:

  • Dynamic, topological and algebraic aspects of cellular automata and discrete dynamical systems
  • Complex systems and complexity theory
  • Algorithmic complexity and information theory
  • Emergent properties of dynamical systems
  • Formal languages, grammars and automata
  • Algorithmic information dynamics
  • Symbolic dynamics and connections to continuous systems
  • Tilings, rewriting and substitution systems
  • Computability theory
  • Synchronous versus asynchronous models
  • Applications of automata to areas such as machine and deep learning, physics, biology, social sciences and others
