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.
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）.
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.
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.
