In theory, the fastest approach for inputs with a small number of terminals uses the dynamic programming, but in practice, stateof-the-art solvers are based on the branch-and-cut method. In this paper, we present a novel separator-based pruning technique for speeding up a theoretically fast DP algorithm. Our empirical evaluation shows that our pruned DP algorithm is quite effective against real-world instances admitting small separators, scales to more than a hundred terminals, and is competitive with a branch-and-cut solver.<\/jats:p>","DOI":"10.1609\/aaai.v33i01.33011520","type":"journal-article","created":{"date-parts":[[2019,9,13]],"date-time":"2019-09-13T05:19:49Z","timestamp":1568351989000},"page":"1520-1527","source":"Crossref","is-referenced-by-count":13,"title":["Separator-Based Pruned Dynamic Programming for Steiner Tree"],"prefix":"10.1609","volume":"33","author":[{"given":"Yoichi","family":"Iwata","sequence":"first","affiliation":[]},{"given":"Takuto","family":"Shigemura","sequence":"additional","affiliation":[]}],"member":"9382","published-online":{"date-parts":[[2019,7,17]]},"container-title":["Proceedings of the AAAI Conference on Artificial Intelligence"],"original-title":[],"link":[{"URL":"https:\/\/ojs.aaai.org\/index.php\/AAAI\/article\/download\/3965\/3843","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/ojs.aaai.org\/index.php\/AAAI\/article\/download\/3965\/3843","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,11,7]],"date-time":"2022-11-07T06:40:37Z","timestamp":1667803237000},"score":1,"resource":{"primary":{"URL":"https:\/\/ojs.aaai.org\/index.php\/AAAI\/article\/view\/3965"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,7,17]]},"references-count":0,"journal-issue":{"issue":"01","published-online":{"date-parts":[[2019,7,23]]}},"URL":"https:\/\/doi.org\/10.1609\/aaai.v33i01.33011520","relation":{},"ISSN":["2374-3468","2159-5399"],"issn-type":[{"value":"2374-3468","type":"electronic"},{"value":"2159-5399","type":"print"}],"subject":[],"published":{"date-parts":[[2019,7,17]]}}}
