Cellular Automata and Discrete Complex Systems

This book constitutes the proceedings from the 31st IFIP WG 1. 5 International Workshop on Cellular Automata and Discrete Complex Systems, AUTOMATA 2025, held in Lille, France, during June 30-July 2, 2025. The 11 full papers and 4 invited papers presented in this proceedings were carefully reviewed and selected from 19 submissions. The AUTOMATA series is the official annual event of IFIP WG 1. 5, the Working Group 5 (on Cellular Automata and Discrete Complex Systems), of the Technical Committee 1 (on Foundations of Computer Science), of the International Federation for Information Processing (IFIP). AUTOMATA is an annual, international, multidisciplinary conference for experts in cellular automata and complex dynamic systems.
