Abstract
There exist many competition systems to determine a winner. Many sports games use the 1-in-2 tournament or its modified version to determine a winner. In this paper, we propose a competition system that can be used when there are many candidates and many random referees to evaluate the candidates. These competitions can be found in the cyber space where many users score many competing apps. We study fairness of our proposed competing system called a multi-stage random tournament in terms of equal probabilities. We also formulate the influence factor of a specific referee under some specific conditions.
