中文摘要:
      摘 要:运动员胜率排名算法对于得到受大家认可的公平的、客观的、全面的乒超运动员排名以及促进乒超运动的稳健发展都是非常重要的。首先总结概括了排名胜率算法的整体需求,简要回顾了传统的绝对胜率算法和2008年提出的“中性权衡胜率差”算法,并指出了这两种算法各自的优缺点。然后,为克服“中性权衡胜率差”算法的缺点,提出了一种名为“动态加权胜率”的算法,并对该算法的性能特点加以详细的理论分析。最后,为了验证本文新提出算法的有效性, 我们把该算法运用到2009年中国乒乓球俱乐部超级联赛的实战成绩中, 并与“中性权衡胜率差”计算结果进行了详细的对比和分析。理论分析和实际应用的结果均表明,新算法优于“中性权衡胜率差”算法, 并且完全满足排名胜率算法的整体需求,具有较高的实用价值。
英文摘要:
      Abstract:The ranking of winning ratio algorithm plays an important role in both achieving a fair, scientific, comprehensive, acceptable ranking for players and promoting the stable development for the China Table Tennis Super League. In this paper, the writer has firstly reviewed the requirement of the ranking of winning ratio, and analyzed the advantages and the shortages of both the traditional absolute winning ratio ranking algorithm and the “natural balanced winning ratio differentia” algorithm introduced in 2008. To avoid and reduce the shortages of the prior works, the writer introduces the “dynamic weighted winning ratio” algorithm, and gives the character and the detailed theoretical analysis of that. To check the validity of the new algorithm, the writer adopts the data from the 2009’s CTTSL to detailed compare the result between the new algorithm and the “natural balanced winning ratio differentia” algorithm. Both the theoretical analysis and the application have reflected that the “dynamic weighted winning ratio” algorithm is better than the “natural balanced winning ratio differential” algorithm, which can meet the requirement of the ratio ranking algorithm better, and thus has a higher practical value.
