Embodiment 1

[0040] Example 1: Such as Figure 1-2 As shown, a competition performance evaluation method based on the theory of social choice, first obtains the referee's preference relationship with the players, and builds the paired preference matrix of the players; then constructs a directed graph according to the paired preference matrix, and calculates The strongest path: Finally, the strongest path matrix is ​​generated, and the final ranking of the players is obtained by comparing the strongest paths between the players.

[0041] The specific steps of the method are as follows:

[0042] Step1. Obtain the referee's preference relationship with the players;

[0043] Suppose the referees gather as R ={ r 1 , r 2 ,..., r m }, the player set is P ={ p 1 , p 2 ,..., p n }, create referee r i A R ( i =1,2,..., m ) To the players p x , p y A P ( x , y =1,2,…, n ) Preference relationship s i ( p x , p y ):

[0044] ① p x ≻ i p y Referee r i Think player p x Better than p y ;

[0045] ② p x ≺...

Embodiment 2

[0063] Example 2: Such as Figure 1-2 As shown, a competition performance evaluation method based on the theory of social choice, first obtains the referee's preference relationship with the players, and builds the paired preference matrix of the players; then constructs a directed graph according to the paired preference matrix, and calculates The strongest path: Finally, the strongest path matrix is ​​generated, and the final ranking of the players is obtained by comparing the strongest paths between the players.

Embodiment 3

[0064] Example 3: Such as Figure 1-2 As shown, a competition performance evaluation method based on social choice theory, the specific implementation steps are as follows:

[0065] 1) Obtain the referee's preference for players;

[0066] In a competition with 10 referees and 5 players, the referees’ preferences for players are as follows:

[0067] 4 referees think p 1 ≻ p 3 ≻ p 4 ≻ p 2 ≻ p 5 ;

[0068] 2 referees think p 3 ≻ p 4 ≻ p 2 ≻ p 5 ≻ p 1 ;

[0069] 3 referees think p 4 ≻ p 5 ≻ p 2 ≻ p 1 ≻ p 3 ;

[0070] 1 referee thinks p 5 ≻ p 2 ≻ p 3 ≻ p 4 ≻ p 1 ;

[0071] 2) Convert the referee's preference relationship to the players into a paired preference matrix through calculation D =[d( p x , p y )] 5×5 , D( p x , p y ) Indicates that the player p x Better than players p y The number of referees. For example, think players p 1 Better than players p 2 There are a total of 4 judges who think that the players p 2 Better than players p 1 There are 6 judges, so d( p 1 , p 2 )=4, d( p 2 , p...

Abstract

The invention relates to a competition score evaluation method based on the social selection theory and belongs to the competition evaluation and colony decision field. According to the method, firstly, competitor preference relations of referees are acquired, and a competitor pairing preference matrix is established on the basis of the competitor preference relations; secondly, according to the pairing preference matrix, a digraph is constructed, and strongest paths are calculated; and lastly, a strongest path matrix is generated, and the final competitor sequence is acquired through comparing the strongest paths of competitors. Through taking consideration of the competitor preference relations of the referees, the digraph is constructed, the strongest paths are further calculated, maneuverability in an ordering process is weakened essentially, and a new method for score evaluation on most subjective competitions is provided.

Description

Technical field [0001] The present invention involves a method of competition evaluation based on the theory of social selection, which is the field of competition assessment and group decision -making. Background technique [0002] With the rapid development of my country's economy and society, more and more competitions appear in all aspects of our lives.In the contests such as literature and art, sports, the results of the competition plays an important role in measuring the level of players, and the factors that determine the results of the competition depends on the following three aspects: first, whether the performance evaluation mechanism is fair; second, the refereeThe subjective will; third, the performance of the athletes. [0003] Zhang Hua et al. (<2011 National Men's Diving Championships The Objective Analysis of Referee Scores>, 2012) pointed out that the player score in the diving competition was determined by the referee scoring, and the performance of the ...
