By generalization of the nodal span context-free recognition algorithm, any algebraic power series is computable in O(n3) steps. The closure of algebraic power series under sequential transduction yields a generous class of reasonable error measures for which optimal analysis is O(n3). Included is minimizing the number of symbol insertions, deletions and/or replacements needed for correction, a special case which has been studied separately.","PeriodicalId":242946,"journal":{"name":"Proceedings of the fifth annual ACM symposium on Theory of computing","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1973-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117147846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
