Manzoni and Umeo have described an algorithm for these (one-dimensional) cellular automata which solves the Firing Squad Synchronization Problem. This algorithm needs linear time (in the number of cells to be synchronized) but for many problem instances it is slower than the optimum time by some positive constant factor. In the present paper we derive lower bounds on possible synchronization times and describe an algorithm which is never slower and in some cases faster than the one by Manzoni and Umeo and which is close to a lower bound (up to a constant summand) in more cases.<\/jats:p>","DOI":"10.1007\/s00236-020-00383-6","type":"journal-article","created":{"date-parts":[[2021,7,19]],"date-time":"2021-07-19T09:05:06Z","timestamp":1626685506000},"page":"451-462","update-policy":"http:\/\/dx.doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A faster algorithm for the Birthday Song Singers Synchronization Problem (FSSP) in one-dimensional CA with multiple speeds"],"prefix":"10.1007","volume":"58","author":[{"given":"Thomas","family":"Worsch","sequence":"first","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2021,7,19]]},"reference":[{"key":"383_CR1","doi-asserted-by":"crossref","unstructured":"Manzoni, L., Porreca, A.E., Umeo, H.: The firing squad synchronization problem on higher-dimensional CA with multiple updating cycles.
