Outline of Final Research Achievements

The Firing Squad Synchronization Problem (FSSP) has been studied extensively for more than fifty years, and a rich variety of FSSP algorithms has been proposed. Here we study the FSSP and gives a unified view point of the classical FSSP on standard and non-standard cellular automata. A part of the results obtained in this work has been presented as four book chapters (Springer Publishing), 25 journal and international conference papers. A class of the smallest 4-state FSSP partial solutions, a reconstruction of the first FSSP algorithm and a 6-state fault-tolerant FSSP protocol are included. An international research exchange has been made through an organization of the three international conferences: AFCA 2016, 2017 and 2018 and an edition of international Journal of Cellular Automata (Vol. 13, No3).
