To realize this potential, mechanisms are needed that allocate vehicles optimally and provide the right incentives to riders. However, many existing approaches consider restricted settings (e.g.,\n\nonly one rider per vehicle\n\nor a common origin for all riders). Moreover,\n\nnaive applications of standard approaches, such as the Vickrey-Clarke-Groves or greedy mechanisms, cannot achieve a polynomial-time, truthful, individually rational and budget balanced mechanism. To address this, we formulate a general ridesharing problem and apply mechanism design to develop a novel mechanism which satisfies all four properties and whose social cost is within 8.6% of the optimal on average.<\/jats:p>","DOI":"10.24963\/ijcai.2021\/38","type":"proceedings-article","created":{"date-parts":[[2021,8,11]],"date-time":"2021-08-11T07:00:49Z","timestamp":1628665249000},"page":"268-275","source":"Crossref","is-referenced-by-count":2,"title":["A Polynomial-time, Truthful, Individually Rational and Budget Balanced Ridesharing Mechanism"],"prefix":"10.24963","author":[{"given":"Tatsuya","family":"Iwase","sequence":"first","affiliation":[{"name":"Toyota Motor Europe NV\/SA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sebastian","family":"Stein","sequence":"additional","affiliation":[{"name":"University of Southampton"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Enrico H.","family":"Gerding","sequence":"additional","affiliation":[{"name":"University of Southampton"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10584","event":{"name":"Thirtieth International Joint Conference on Artificial Intelligence {IJCAI-21}","theme":"Artificial Intelligence","location":"Montreal, Canada","acronym":"IJCAI-2021","number":"30","sponsor":["International Joint Conferences on Artificial Intelligence Organization (IJCAI)"],"start":{"date-parts":[[2021,8,19]]},"end":{"date-parts":[[2021,8,27]]}},"container-title":["Proceedings of the Thirtieth International Joint Conference on Artificial Intelligence"],"original-title":[],"deposited":{"date-parts":[[2021,8,11]],"date-time":"2021-08-11T07:01:03Z","timestamp":1628665263000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ijcai.org\/proceedings\/2021\/38"}},"subtitle":[],"proceedings-subject":"Artificial Intelligence Research Articles","short-title":[],"issued":{"date-parts":[[2021,8]]},"references-count":0,"URL":"https:\/\/doi.org\/10.24963\/ijcai.2021\/38","relation":{},"subject":[],"published":{"date-parts":[[2021,8]]}}}
