Description A new solution for the Firing Squad Synchronization Problem (FSSP) on two-dimensional square arrays is presented and its correctness is demonstrated in detail. Our new solution is time as well as communication optimal (the so-called minimal time 1-bit solution). In addition, it is shown that the technique developed and the results obtained allow also to solve in optimal time & communication FSSP for several other variants of this problem on networks shaped as square grids (with four Generals), square toruses and rings. This research has been completed while the first author was visiting the Dipartimento di Informatica ed Applicazioni, Universit degli Studi di Salerno. Work partially supported by MIUR grant ex-60% 2003 Universit di Salerno. The first author is also supported by the grant GAČR, 201/04/1153.
