Scope

Aims, scope and focus

International Journal of Unconventional Computing is published by Old City Publishing and is in Zone 4 of Computer Science in the CAS Journal Ranking (2025 upgraded edition). By OpenAlex counts of its recent articles, its largest topics are DNA and Biological Computing, Cellular Automata and Applications and Modular Robots and Swarm Intelligence, together about 32.6% of its articles. (generated from OpenAlex topic counts and CAS ranking data)

The International Journal of Unconventional Computing offers the opportunity for rapid publication of theoretical and experimental results in non-classical computing. Specific topics include but are not limited to: physics of computation (e.g. conservative logic, thermodynamics of computation, reversible computing, quantum computing, collision-based computing with solitons, optical logic) chemical computing (e.g. implementation of logical functions in chemical systems, image processing and pattern recognition in reaction-diffusion chemical systems and networks of chemical reactors) bio-molecular computing (e.g. conformation based, information processing in molecular arrays, molecular memory) cellular automata as models of massively parallel computing complexity (e.g. computational complexity of non-standard computer architectures; theory of amorphous computing; artificial chemistry) logics of unconventional computing (e.g. logical systems derived from space-time behavior of natural systems; non-classical logics; logical reasoning in physical, chemical and biological systems) smart actuators (e.g. molecular machines incorporating information processing, intelligent arrays of actuators) novel hardware systems (e.g. cellular automata VLSIs, functional neural chips) mechanical computing (e.g. micromechanical encryption, computing in nanomachines, physical limits to mechanical computation).
