Abstract

The International Young Physicists' Tournament is an established team-oriented scientific competition between high school students from 37 countries on 5 continents. The competition consists of scientific discussions called Fights. Three or four teams participate in each Fight, while rotating the roles of Presenter, Opponent, Reviewer, and Observer among them. The rules of a few countries require that each team announces in advance three problems they will present at the regional tournament. The task of the organizers is to choose the composition of Fights in such a way that each team presents each of its chosen problems exactly once and within a single Fight no problem is presented more than once. Besides formalizing these feasibility conditions, in this paper we formulate several additional fairness criteria for tournament schedules. We show that the fulfillment of some of them can be ensured by constructing suitable edge colorings in bipartite graphs. To find fair schedules, we propose integer linear programs and test them on real as well as randomly generated data.

对公平时间表的追求:国际青年物理学家锦标赛。

国际青年物理学家锦标赛是一项由来自五大洲37个国家的高中生参加的以团队为导向的科学竞赛。比赛包括被称为“战斗”的科学讨论。每场比赛有三到四个团队参加，同时轮流扮演演示者、对手、评审和观察员的角色。一些国家的规则要求每队提前宣布他们将在地区锦标赛上提出的三个问题。组织者的任务是选择比赛的组成方式，每个队伍只提出一次所选的问题，并且在一场比赛中不能提出超过一次的问题。除了形式化这些可行性条件外，本文还制定了几个额外的比赛赛程公平性标准。我们证明了在二部图中构造合适的边着色可以保证其中一些的实现。为了找到公平的调度，我们提出了整数线性规划，并在真实和随机生成的数据上进行了测试。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
