Heuristics for the robust vehicle routing problem with time windows
Braaten, Simen V.; Gjønnes, Ola; Hvattum, Lars Magnus; Tirado, Gregorio (Peer reviewed; Journal article, 2017)Uncertainty is frequently present in logistics and transportation, where vehicle routing problems play a crucial role. However, due to the complexity inherent in dealing with uncertainty, most research has been devoted to ... -
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 ... -
