In conjunction with the 16th INTERNATIONAL CONFERENCE ON PARALLEL PROCESSING
AND APPLIED MATHEMATICS - PPAM 2026

Introduction:
=============
Collective aspects of complex systems attract researchers from many disciplines, covering theoretical foundations and real-world applications. Local interactions and simple rules enable effective modeling of complex collective behavior. This workshop has been a forum for exchanging knowledge in the field of Complex Collective Systems for several years - this is the 9th edition since 2009.
Accepted papers will be published in the PPAM Conference Proceedings by Springer-Verlag (LNCS series).

Papers must not exceed 15 pages (LNCS format). Submissions are handled via the PPAM website (https://ppam.edu.pl) under the Workshop on Complex Collective Systems track.

Topics
=======
* Models of complex systems
* Agent-based modeling
* Cellular automata for real phenomena
* Pedestrian and traffic dynamics
* AI agents and complex systems
