A natural notion of strength of alternatives in a tournament is a generalized king: an alternative is said to be a k<\/jats:italic>-king<\/jats:italic> if it can reach every other alternative in the tournament via a directed path of length at most k<\/jats:italic>. In this paper, we provide an almost complete characterization of the probability threshold such that all, a large number, or a small number of alternatives are k<\/jats:italic>-kings with high probability in two random models. We show that, perhaps surprisingly, all changes in the threshold occur in the range of constant k<\/jats:italic>, with the biggest change being between $$k=2$$<\/jats:tex-math>\n \n k<\/mml:mi>\n =<\/mml:mo>\n 2<\/mml:mn>\n <\/mml:mrow>\n <\/mml:math><\/jats:alternatives><\/jats:inline-formula> and $$k=3$$<\/jats:tex-math>\n \n k<\/mml:mi>\n =<\/mml:mo>\n 3<\/mml:mn>\n <\/mml:mrow>\n <\/mml:math><\/jats:alternatives><\/jats:inline-formula>. In addition, we establish an asymptotically tight bound on the probability threshold for which all alternatives are likely able to win a single-elimination tournament under some bracket.<\/jats:p>","DOI":"10.1007\/s10458-022-09557-7","type":"journal-article","created":{"date-parts":[[2022,4,27]],"date-time":"2022-04-27T09:03:09Z","timestamp":1651050189000},"update-policy":"http:\/\/dx.doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Generalized kings and single-elimination winners in random tournaments"],"prefix":"10.1007","volume":"36","author":[{"given":"Pasin","family":"Manurangsi","sequence":"first","affiliation":[]},{"given":"Warut","family":"Suksompong","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2022,4,27]]},"reference":[{"key":"9557_CR1","doi-asserted-by":"publisher","first-page":"493","DOI":"10.1613\/jair.4856","volume":"54","author":"H Aziz","year":"2015","unstructured":"Aziz, H., Brill, M., Fischer, F., Harrenstein, P., Lang, J., & Seedig, H.
