The relationship between professional tournament structure on the national level and success in men's professional tennis.
2003
This article discusses the relationship between a nation's men's professional tennis tournament structure and that nation's success in the international men's game. The 2002 men's professional tennis tournament calendar provided the distribution of events on the top thirty nations. Criteria for a nation's success in men's professional tennis were: nation's number of players with ATP points, nation's number of players in the top 200 ranking, and the combined ATP ranking of a nation's top 5 male players. Pearson correlations were performed between the number of tournaments and each criterion. Results showed a considerable variation in the number of events ranging between 67 (United States) an…
Bivariate analysis of taekwondo actions: The effectiveness of techniques and tactics in an Olympic taekwondo championship.
2020
This paper describes the effectiveness of technical-tactical actions performed during a tournament. A total of 14,145 actions of the 2012 London Olympic Games were analysed. Differences emerged in the use of tactics, techniques, zones, legs and guard to score. Regarding tactics, anticipatory counterattacks were the most effective for scoring one and three points. Circular techniques were the most effective for scoring one point, linear to score three points, and spin techniques to score two and four points. Actions to the chest results in a score of one to two points and actions to the head in a score of three to four points. The rear leg was more effective in scoring one, two and four poin…
La théorie des tournois appliquée aux joueurs de tennis professionnels : peut-on encore parler d’incitations à la performance ?
2011
L’objet de cet article est d’appliquer la theorie des tournois aux joueurs du tennis professionnel masculin. Deux nouveaux indicateurs de mesure de la performance des joueurs sont introduits, afin de prendre en compte le niveau de l’opposition. Les estimations econometriques sont effectuees, par la methode des Moindres Carres Ordinaires, sur l’ensemble des tournois disputes par les 30 meilleurs joueurs classes a l’ATP au cours de l’annee 2007. Les resultats obtenus valident bien, conformement a une des predictions de la theorie des tournois, l’existence d’un effet incitatif associe a la performance, a savoir qu’une structure de prix inegalitaire entre les tours du tournoi augmente la perfor…

On the Generalizability of Programs Synthesized by Grammar-Guided Genetic Programming
2021
Grammar-guided Genetic Programming is a common approach for program synthesis where the user’s intent is given by a set of input/output examples. For use in real-world software development, the generated programs must work on previously unseen test cases too. Therefore, we study in this work the generalizability of programs synthesized by grammar-guided GP with lexicase selection. As benchmark, we analyze proportionate and tournament selection too. We find that especially for program synthesis problems with a low output cardinality (e.g., a Boolean output) lexicase selection overfits the training cases and does not generalize well to unseen test cases. An analysis using common software metr…
