In this paper we present a number of approaches for the random generation of value-based argumentation frameworks (VAFs) built on n arguments and using k values. Via an empirical study we consider the behaviour of the associated random VAFs with respect to the issue of how many arguments within them have the property of being &amp;ldquo;objectively accepted&amp;rdquo;. Our studies indicate that the property of having no objectively accepted argument exhibits a so-called &amp;ldquo;phasetransition effect&amp;rdquo;, similar in nature to those observed in many other well-established AI studies.<\/jats:p>","DOI":"10.3233\/978-1-61499-436-7-261","type":"book-chapter","created":{"date-parts":[[2025,2,20]],"date-time":"2025-02-20T12:06:08Z","timestamp":1740053168000},"source":"Crossref","is-referenced-by-count":0,"title":["Properties of Random VAFs and Implications for Efficient Algorithms"],"prefix":"10.3233","author":[{"family":"Dunne Paul E.","sequence":"additional","affiliation":[]},{"family":"Atkinson Katie","sequence":"additional","affiliation":[]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","Computational Models of Argument"],"original-title":[],"deposited":{"date-parts":[[2025,2,20]],"date-time":"2025-02-20T12:57:21Z","timestamp":1740056241000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medra.org\/servlet\/aliasResolver?alias=iospressISSNISBN&issn=0922-6389&volume=266&spage=261"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/978-1-61499-436-7-261","relation":{},"ISSN":["0922-6389"],"issn-type":[{"value":"0922-6389","type":"print"}],"subject":[],"published":{"date-parts":[[2014]]}}}
