A few simple extensions allow the algorithm to handle situations in which the user has an incorrect plan. However, it turns out that recognizing structural errors is computationally a much more complex problem than recognizing plans with simple constraint violations. Four algorithms are presented here, starting with a direct adaptation of A* for recognizing correct plans, and progressing to an optimized algorithm for recognizing violated, ill-formed plans. <\/jats:p>","DOI":"10.1142\/s0218001490000162","type":"journal-article","created":{"date-parts":[[2004,11,29]],"date-time":"2004-11-29T02:14:37Z","timestamp":1101694477000},"page":"233-244","source":"Crossref","is-referenced-by-count":0,"title":["A MODIFIED A* ALGORITHM FOR ROBUST PLAN RECOGNITION"],"prefix":"10.1142","volume":"04","author":[{"given":"RANDALL J.","family":"CALISTRI","sequence":"first","affiliation":[{"name":"Computer Science Department, Brown University, Providence, RI 02912, USA"}]}],"member":"219","published-online":{"date-parts":[[2011,11,21]]},"container-title":["International Journal of Pattern Recognition and Artificial Intelligence"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.worldscientific.com\/doi\/pdf\/10.1142\/S0218001490000162","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,8,7]],"date-time":"2019-08-07T02:14:53Z","timestamp":1565144093000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.worldscientific.com\/doi\/abs\/10.1142\/S0218001490000162"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1990,6]]},"references-count":0,"journal-issue":{"issue":"02","published-online":{"date-parts":[[2011,11,21]]},"published-print":{"date-parts":[[1990,6]]}},"alternative-id":["10.1142\/S0218001490000162"],"URL":"https:\/\/doi.org\/10.1142\/s0218001490000162","relation":{},"ISSN":["0218-0014","1793-6381"],"issn-type":[{"value":"0218-0014","type":"print"},{"value":"1793-6381","type":"electronic"}],"subject":[],"published":{"date-parts":[[1990,6]]}}}
