The system provides famous AI examples such as Muddy children and Russian cards. The system also allows to implement user's own examples via the description of a Kripke model or via its generation by the generic tableau method prover MetTeL2.<\/jats:p>","DOI":"10.24963\/ijcai.2018\/862","type":"proceedings-article","created":{"date-parts":[[2018,7,5]],"date-time":"2018-07-05T01:49:10Z","timestamp":1530755350000},"page":"5859-5861","source":"Crossref","is-referenced-by-count":2,"title":["Hintikka's World: Agents with Higher-order Knowledge"],"prefix":"10.24963","author":[{"given":"Fran\u00e7ois","family":"Schwarzentruber","sequence":"first","affiliation":[{"name":"Univ Rennes, CNRS, IRISA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10584","event":{"number":"27","sponsor":["International Joint Conferences on Artificial Intelligence Organization (IJCAI)"],"acronym":"IJCAI-2018","name":"Twenty-Seventh International Joint Conference on Artificial Intelligence {IJCAI-18}","start":{"date-parts":[[2018,7,13]]},"theme":"Artificial Intelligence","location":"Stockholm, Sweden","end":{"date-parts":[[2018,7,19]]}},"container-title":["Proceedings of the Twenty-Seventh International Joint Conference on Artificial Intelligence"],"original-title":[],"deposited":{"date-parts":[[2018,7,5]],"date-time":"2018-07-05T01:56:32Z","timestamp":1530755792000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ijcai.org\/proceedings\/2018\/862"}},"subtitle":[],"proceedings-subject":"Artificial Intelligence Research Articles","short-title":[],"issued":{"date-parts":[[2018,7]]},"references-count":0,"URL":"https:\/\/doi.org\/10.24963\/ijcai.2018\/862","relation":{},"subject":[],"published":{"date-parts":[[2018,7]]}}}
