This paper explores a new perspective of finding the best tournament structures by focusing on two aspects (apart from the number of matches): competitiveness development and ranking precision. Competitiveness development emphasizes the importance of participants’ motivation while keeping the matches exciting whereas ranking precision reflects the persuasiveness of tournament result to its participants. To address competitiveness development, this paper proposes a new method that visualizes tournament structures using a tree-like graphical model called progress tree. In addition, ranking precision is addressed by considering the similarities and qualities of the ranking process by the sorting algorithm during the ranking process. With respect to these two aspects, several well-known tournament structures such as the single elimination, double elimination, Round-Robin, and Swiss systems were analyzed. Although each tournament has its own pros and cons, none of them can thoroughly convince all participants of the tournament results while keeping the matches strongly motivating. As such, a new tournament structure called Reaper tournament system with its variants, are proposed. The Reaper tournament system with its variants were evaluated on simulated football matches and validated with real-world data of previous football tournaments. Thence, practical insights into tournament structures are obtained and possible future works are discussed.

模拟比赛结构中的竞争力和准确性：收割者比赛系统

本文通过关注两个方面（除了比赛数），探索了寻找最佳比赛结构的新视角：竞争力发展和排名精度。竞争力的发展强调了参与者动机的重要性，同时又要保持比赛的激动性，而排名精度则反映了比赛结果对其参与者的说服力。为了解决竞争力的发展，本文提出了一种新方法，该方法使用称为进度树的树状图形模型来可视化锦标赛结构。另外，通过在排序过程中通过排序算法考虑排序过程的相似性和质量来解决排序精度。关于这两个方面，分析了几种著名的锦标赛结构，例如单淘汰，双淘汰，循环赛和瑞士系统。尽管每个比赛都有自己的优缺点，但是在保持比赛积极性的同时，他们都无法完全说服所有参与者参加比赛。因此，提出了一种新的比赛结构，称为“收割者比赛系统”及其变种。该收割机在模拟足球比赛中评估了具有其变体的锦标赛系统，并使用先前足球锦标赛的真实数据进行了验证。因此，可以获得有关锦标赛结构的实际见解，并讨论了可能的未来工作。
