Abstract We formulate two fairness principles and characterize the league competition systems that satisfy them. The first principle requires all players should have same chance of being final winner if are equally strong, while second states not favor weaker players. apply these requirements to a class which includes round-robin tournaments as particular case.

in it no longer achieving the functionality for which it was originally intended. Diagnostic algorithms (DAs) (1) detect malfunctioning systems, (2) isolate the faulty component or components that cause the malfunction, and possibly (3) repair the system to restore its functionality. The fundamental challenge of diagnosis is that the system is only partially observable. Therefore, diagnostic al...

Events such as RoboCup, the Netflix Prize, the Trading Agent Competition, the International Planning Competition, the General Game Playing Competition, the AAAI Computer Poker Competition, and the DARPA Grand Challenge have succeeded in raising awareness and stimulating research about their respective topics. The empirical, problem-oriented nature of these competitions can be an important count...

The purpose of the study was to analyse occurrence different boulder types and athletes’ success rates in international competitions contribute performance structure competitive bouldering. Therefore, we classified 448 sections final rounds 14 Bouldering World Cups 2017 2018 using video analysis. We conducted analysis frequencies, chi-square tests, binomial regressions ANOVA for respective with...

The RoboCup simulation league is traditionally the league with the largest number of teams participating, both at the international competitions and worldwide. 2011 was no exception, with a total of 39 teams entering the 2D and 3D simulation competitions. This paper presents the champions of the competitions, WrightEagle from the University of Science and Technology of China in the 2D competiti...

The 71st Scientific Sessions of the American Heart Association were held in Dallas, Tex, November 8 through 11, 1998. A traditional highlight of the annual AHA Scientific Sessions is the recognition of excellence in clinical and basic cardiovascular research via the Scientific Councils’ distinguished lectureships, awards, and Young Investigator competitions. The awardees and nominees for these ...

The M3-Competition continues to improve the design of forecasting competitions: It examines more series than any previous competition, improves error analyses. and includes commercial forecasting programs as competitors. To judge where to go from here, I step back to look at the M-Competitions as a whole. I discuss the advantages of the M-Competitions in hopes that they will be retained, descri...

OBJECTIVE To assess intraocular pressure (IOP) in conditioned equine athletes and document changes with exercise. A secondary objective was to assess associations between IOP and heart rate, as well as with other subjective physical parameters. SAMPLE POPULATION Horses were evaluated during 50 mile endurance ride competitions. Data were collected on 69 horses during five different competition...

Background: Robotics competitions are increasingly popular and potentially provide an on-ramp to computer science, which is currently highly gender imbalanced. However, within competitive robotics teams, student participation in programming is not universal. This study gathered surveys from over 500 elementary, middle, and high school robotics competition participants to examine (1) whether pro...
