In this paper we analyse the possible occurrence of polymorphic attacks in the context of the ASPIC+ formalism, pointing out that they are not just a technical artifact but can occur is some practical reasoning context. While in ASPIC+ polymorphic attacks are dealt with in an implicit and fixed way, we propose a tunable approach to their treatment, based on the novel notion of defeat generation function. In particular, we introduce a property of faithfulness for this function and prove that it guarantees the satisfaction of the rationality postulates proposed by Caminada and Amgoud, showing that a greater flexibility in the treatment of polymorphic attacks can be achieved without affecting the technical soundness of the formalism.<\/jats:p>","DOI":"10.3233\/faia260830","type":"book-chapter","created":{"date-parts":[[2026,9,10]],"date-time":"2026-09-10T21:08:33Z","timestamp":1789074513000},"source":"Crossref","is-referenced-by-count":0,"title":["On Polymorphic Attacks in ASPIC+"],"prefix":"10.3233","author":[{"given":"Pietro","family":"Baroni","sequence":"first","affiliation":[{"name":"DII - University of Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Federico","family":"Cerutti","sequence":"additional","affiliation":[{"name":"DII - University of Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Massimiliano","family":"Giacomin","sequence":"additional","affiliation":[{"name":"DII - University of Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","Computational Models of Argument"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/FAIA260830","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,9,10]],"date-time":"2026-09-10T21:08:33Z","timestamp":1789074513000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/FAIA260830"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,9,10]]},"ISBN":["9781643686806"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/faia260830","relation":{},"ISSN":["0922-6389","1879-8314"],"issn-type":[{"value":"0922-6389","type":"print"},{"value":"1879-8314","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,9,10]]}}}
