竞赛背景

        In order to cultivate students' innovative consciousness and ability to solve practical problems by using mathematical methods and computer technology, more than 20 universities have decided to      jointly hold a multi-school mathematics modeling contest. This students' mathematical modeling           contest provides a warm up opportunity for the US mathematics contest. The league tournament has 3 kind of questions: engineering management, network and big data. ‘Identify the error connections in   the network’ is the network type of contest.               The network is a powerful tool to describe the structure of a real system—— the social network  describes the relationship between human beings, and the World Wide Web describes the hyperlink   relationship between web pages. With the development of modern technology, we have accumulated more and more network data, but the data is partially incomplete, inaccurate or sometimes distorted. For example, in the biological network, some early proved existing gene-gene and protein-protein        interrelations are overturned by new experiments with higher accuracy.

奖项

        1. ‘Identify the error connections in the network’ is the network type of contest, the final algorithm of this contest would have great impact on the final three contests results.               2. The multi-university mathematics contest has set up a grand prize, first prize, second prize,     third prize, for more information about prizes, please click(www.saikr.com/apmcm).

参赛与组队规则

所有参赛人员及队伍,视为已同意《DC竞赛作弊管理规则》及其他相关规定。队长对其队员的参赛行为负责。

        When registering the www.pkbigdata.com, the register email must keep the same as the             registration on the www.saikr.com/apmcm. Besides, the team name on the pkbigdata.com is your       team number, for example 0001, 1100.

        Contestant could submit the result after real name authentication. Each team or contestant could register only one team number as the team name. The following behaviors are forbidden: not register with real name authentication, register multiple team number or name, not use the team number as    the team name, etc. We would cancel the qualification of the contestant.            Also, contestant could join the ‘Identify the error connections in the network’ separately. 团队人数上限3人。 在第一阶段的最后3天无法新建队伍,但是可以加入其它队伍。 在最后一个阶段最后3天无法新建队伍,无法加入队伍。 竞赛进入历史阶段后解除一切限制,注意:答辩队伍成员仅限活跃期间加入的成员。

评分标准

评分算法
other
评分标准         For any of the above network, if the real number of error connections is R, then the player          should submit how those R error connections are identified in a standard format(For the format of the submission, please see the ‘result submission’ examples. ).         If r out of R error connections are identified correctly in the submission, then the score is              S = r / R.         The total score obtained by the players in all 6 networks is the only measure of the accuracy of   the algorithm.
