A composition\nproblem for web services is to decide if a given web service can be constructed\nfrom a given set of web services; where the construction is understood as a\nsimulation of the specification by a fully asynchronous product of the given\nservices. We show an EXPTIME-lower bound for this problem, thus matching the\nknown upper bound. Our result also applies to richer models of web services,\nsuch as the Roman model.<\/jats:p>","DOI":"10.2168\/lmcs-4(2:5)2008","type":"journal-article","created":{"date-parts":[[2008,6,3]],"date-time":"2008-06-03T13:29:59Z","timestamp":1212499799000},"source":"Crossref","is-referenced-by-count":11,"title":["A lower bound on web services composition"],"prefix":"10.46298","volume":"Volume 4, Issue 2","author":[{"given":"Anca","family":"Muscholl","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Igor","family":"Walukiewicz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"25203","published-online":{"date-parts":[[2008,5,15]]},"container-title":["Logical Methods in Computer Science"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/lmcs.episciences.org\/824\/pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/lmcs.episciences.org\/824\/pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,4,11]],"date-time":"2023-04-11T19:57:02Z","timestamp":1681243022000},"score":1,"resource":{"primary":{"URL":"https:\/\/lmcs.episciences.org\/824"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2008,5,15]]},"references-count":0,"URL":"https:\/\/doi.org\/10.2168\/lmcs-4(2:5)2008","relation":{"is-same-as":[{"id-type":"arxiv","id":"0804.3105","asserted-by":"subject"},{"id-type":"doi","id":"10.48550\/arXiv.0804.3105","asserted-by":"subject"}]},"ISSN":["1860-5974"],"issn-type":[{"type":"electronic","value":"1860-5974"}],"subject":[],"published":{"date-parts":[[2008,5,15]]},"article-number":"824"}}
