D esign competitions are becoming increasingly common , especially in the field of mobile robots. The sponsorship of such competitions ranges from local clubs of enthusiasts to large professional organizations , such as the American Association for Artificial Intelligence (AAAI), which sponsors the annual AAAI Mobile Robot Competition and Exhibition as part of their annual conference. Awards fo...

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.

The standard three-state voter model is enlarged by including the outside pressure favouring one of the three choices and by adding some biased internal random noise. The Monte Carlo simulations are motivated by states with the population divided into three groups of various affinities to each other. We show the crucial influence of the boundaries for moderate lattice sizes like 500 × 500. By r...

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 idea that some geographic regions, known as shatterbelts, are more conflict-prone than others has appeared and resurfaced in geopolitical writings throughout the twentieth century. Yet much of that work has been tautological or impressionistic. We attempt to sort out the conceptual components of shatterbelts from their hypothesized consequences, and to test propositions about the effects of...

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 ...
