One of the systems, related to the equal-sum partition problem, is "perfect, " since it yields perfectly balanced groups. The other system, which uses the classical scheme of extracting teams from pots, is heuristic and gives results where the groups have very similar scores. We apply our results to Federation Internationale de Football Association (FIFA) Soccer World Cups and show that our proposals are much better than the FIFA system and also outperform other recently developed systems. 000075965 536__ $$9info:eu-repo/grantAgreement/ES/MICINN/MTM2017-83812-P$$9info:eu-repo/grantAgreement/ES/MINECO/MTM2014-53340-P 000075965 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000075965 590__ $$a2.987$$b2019 000075965 591__ $$aMANAGEMENT$$b90 / 226 = 0.398$$c2019$$dQ2$$eT2 000075965 591__ $$aOPERATIONS RESEARCH & MANAGEMENT SCIENCE$$b23 / 83 = 0.277$$c2019$$dQ2$$eT1 000075965 592__ $$a1.018$$b2019 000075965 593__ $$aBusiness and International Management$$c2019$$dQ1 000075965 593__ $$aComputer Science Applications$$c2019$$dQ1 000075965 593__ $$aStrategy and Management$$c2019$$dQ1 000075965 593__ $$aManagement of Technology and Innovation$$c2019$$dQ1 000075965 593__ $$aManagement Science and Operations Research$$c2019$$dQ2 000075965 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000075965 700__ $$0(orcid)0000-0002-7615-2559$$aLopez, F.J.$$uUniversidad de Zaragoza 000075965 7102_ $$12007$$2265$$aUniversidad de Zaragoza$$bDpto.
