This paradigm is particularly appropriate to model competition between agents, a leader and a follower, acting sequentially.<br \/>\nIn this talk I will first focus the simplest bilevel problems, those that are linear. In particular I will discuss some recent results showing that these problems are already extremely challenging.<br \/>\nIn a second part, I will talk about a family of bilevel problems called network pricing problems, in which tolls must be determined on a specified subset of arcs of a multicommodity transportation network. The leader or first level corresponds to the profit maximizing owner of the subset of arcs and the follower to users traveling at minimum cost between nodes of the network.[:]<\/p>","protected":false},"excerpt":{"rendered":"<p>[:es]T\u00edtulo:\u00a0Bilevel optimization and pricing problems<br \/>\nPonente:\u00a0Martine Labb\u00e9 (Universit\u00e9 Libre de Bruxelles)<br \/>\nOrganizador:\u00a0\u00a0 Mercedes Landete<br \/>\nFecha: Jueves 12 de diciembre a las 11:00 horas.<br \/>\nLugar:\u00a0 Aulas 0.1 y 0.2 del Edificio Torretamarit,\u00a0Universidad Miguel Hern\u00e1ndez\u00a0(Campus de Elche)<br \/>\nResumen:\u00a0A bilevel optimization problem consists in an optimization problem in which some of the constraints specify that a subset of variables must be an optimal [&#8230;]<\/p>","protected":false},"author":6202,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_links_to":"","_links_to_target":""},"categories":[4,873],"tags":[],"_links":{"self":[{"href":"https:\/\/cio.umh.es\/en\/wp-json\/wp\/v2\/posts\/15244"}],"collection":[{"href":"https:\/\/cio.umh.es\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/cio.umh.es\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/cio.umh.es\/en\/wp-json\/wp\/v2\/users\/6202"}],"replies":[{"embeddable":true,"href":"https:\/\/cio.umh.es\/en\/wp-json\/wp\/v2\/comments?post=15244"}],"version-history":[{"count":0,"href":"https:\/\/cio.umh.es\/en\/wp-json\/wp\/v2\/posts\/15244\/revisions"}],"wp:attachment":[{"href":"https:\/\/cio.umh.es\/en\/wp-json\/wp\/v2\/media?parent=15244"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/cio.umh.es\/en\/wp-json\/wp\/v2\/categories?post=15244"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/cio.umh.es\/en\/wp-json\/wp\/v2\/tags?post=15244"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
