• Artificial grass and genuine football : the evolution of artificial turf 

      Haugen, Kjetil K.; Heen, Knut Peder (Peer reviewed; Journal article, 2019)
      The article formulates, solves and draws inference from a game model intended to shed light on the evolution of artificial turf in professional European football (soccer). The main results indicate that quality of teams ...
    • Downstream logistics optimization at EWOS Norway 

      Branda, Martin; Haugen, Kjetil K.; Novotný, Jan; Olstad, Asmund (Peer reviewed; Journal article, 2017)
      The Norwegian company EWOS AS produces fish feed for the salmon farming industry, supplying approximately 300 customers spread along the coast of Norway. The feed is produced at three factory locations and distributed by ...
    • Equilibrium team selection in football under win or profit maximisation 

      Haugen, Kjetil K. (Peer reviewed; Journal article, 2017)
      This article applies mathematical methods to investigating (extremely) simplified versions of the team selection problem for football managers. The team selection problem - obviously a game problem - is analysed game ...
    • Event corruption : a game theoretic approach 

      Haugen, Kjetil K.; Solberg, Harry Arne (Peer reviewed; Journal article, 2018)
      This article applies economics of doping theory (game theory) to corruption. Similarities, and significant differences between the two topics are identified. As a consequence of such differences, the corruptive action - ...
    • A game theory explanation for menstrual synchrony : the harem paradox 

      Haugen, Kjetil K. (Peer reviewed; Journal article, 2022)
      The 50th anniversary of the McClintock effect deserves a new view on the subject. This paper applies (evolutionary) game theory to gain further insight. Among interesting results are strong indications of Nash equilibria ...
    • A heuristic for finding cheating in chess 

      Haugen, Kjetil K.; Heen, Knut Peder; Smerdon, David C.; Nilssen, Tore (Peer reviewed; Journal article, 2023)
      This article argues by casual empirics that a low draw percent in chess may work as a simplified cheating indicator. Data from a large number of historical chess games (53331) indicate that this extremely simple heuristic ...
    • In-game betting and the Kelly criterion 

      Andersen, Robin; Hassel, Vegard; Hvattum, Lars Magnus; Stålhane, Magnus (Peer reviewed; Journal article, 2020)
      When a bet with a positive expected return is available, the Kelly criterion can be used to determine the fraction of wealth to wager so as to maximize the expected logarithmic return on investment. Several variants of the ...
    • The manager sack race game 

      Haugen, Kjetil K. (Peer reviewed; Journal article, 2021)
      This article applies game theory to explain why football clubs have a tendency to sack their managers when relegation is a realistic option. As opposed to coach succession literature, which typically reports contradiction ...
    • Measuring uncertainty of outcome : an analytic approach 

      Haugen, Kjetil K. (Peer reviewed; Journal article, 2019)
      This article proposes an alternative mathematical formulation to one (among many) ways of estimating Uncertainty of Outcome. This alternative formulation holds potential to make such estimation processes easier for both ...
    • Point score systems and football coaching secrecy 

      Haugen, Kjetil K. (Peer reviewed; Journal article, 2016)
      In this paper, a game between two football (soccer) teams is analysed. The focus is on how the choice of point score system may affect Nash equilibria in a given simultaneous game and a corresponding sequential version. ...
    • Predicting football tables by a maximally parsimonious model 

      Haugen, Kjetil K.; Owren, Brynjulf (Peer reviewed; Journal article, 2018)
      This paper presents some useful mathematical results concerned with football table prediction. In addition, some empirical results indicate that an alternative methodology for football table prediction may produce high ...
    • The trade-off between goals and uncertainty of outcome in professional team sports 

      Haugen, Kjetil K.; Arntzen, Halvard (Peer reviewed; Journal article, 2022)
      Based on an assumption of an existing scoring probability difference between two teams engaged in a football match, the conditional probability distribution given the number of goals in the match for the low quality team ...
    • Uncertainty of outcome and varying fan preferences : a game theoretic approach 

      Haugen, Kjetil K. (Peer reviewed; Journal article, 2016)
      This paper applies simple game theory to investigate an equilibrium link between composition of football clubs’ fans preferences and the clubs’ talent acquisition decisions. Such a link is identified, and wealth of the ...
    • Who are the real top scorers : algorithmically resorting a top scorer list by a limited set of preference assumptions 

      Haugen, Kjetil K. (Peer reviewed; Journal article, 2020)
      This article presents an algorithm, which by taking both goals scored as well as matches played into account, is meant to provide \more sensible" top scorer lists in football. The algorithm computes Upper Hulls recursively ...
