Fair draws for group rounds in sport tournaments 2019 Access copy available to the general public Unrestricted We propose two draw systems for the group round of sport tournaments where there are some geographical and/or seeding restrictions. 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. info:eu-repo/grantAgreement/ES/MICINN/MTM2017-83812-P info:eu-repo/grantAgreement/ES/MINECO/MTM2014-53340-P info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 2.987 2019 MANAGEMENT 90 / 226 = 0.398 2019 Q2 T2 OPERATIONS RESEARCH & MANAGEMENT SCIENCE 23 / 83 = 0.277 2019 Q2 T1 1.018 2019 Business and International Management 2019 Q1 Computer Science Applications 2019 Q1 Strategy and Management 2019 Q1 Management of Technology and Innovation 2019 Q1 Management Science and Operations Research 2019 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0002-7615-2559 Lopez, F.J.
