It has been nearly eighty years since 1930 1 Football World Cup started in Uruguay. The scale and influence of the competition have gradually expanded, and teams from all continents have participated so far. The number of participants and the competition system on all continents are constantly changing.
Since 1998, the quota has changed as follows:
98: Asia 3.5, Europe 15( 1 host), South America 5( 1 defending champion), Africa 5, Central and North America 3, Oceania 0.5.
Nothing has changed! What has changed is the rules of overtime!
Neither silver ball nor the original golden ball method was used in this World Cup.
The sudden death law has been abolished.
In February 2004, FIFA announced at its annual meeting 1 18 that the overtime system became one of the main topics of the meeting. Finally, after many discussions, the FIFA Executive Committee decided to cancel the current "golden ball system" and "silver ball system" and restore the overtime system to the traditional system from the World Cup, that is, if the two sides are still tied at the end of overtime, they will enter a penalty shootout.
2002: Asia 4.5(2 hosts), Europe 14.5( 1 defending champion), Africa 5, South America 4.5, Central and North America 3 and Oceania 0.5.
2006: Asia 4.5, Europe 14( 1 host), Africa 5, South America 4.5, Central and North America 3.5 and Oceania 0.5.
20 10 the latest scheme: there are 32 teams participating in the world cup, among which the host country south Africa directly advances to the finals. In addition, among the 3 1 seats, Europe will get 13 seats and directly advance to the finals, and Africa will have 5 seats. Central and North America and the Caribbean won 3.5 seats, South America continued to win 4.5 seats, and the fifth place in the South American regional qualifiers will compete with the fourth place in North America for a ticket. Asia still holds 4.5 seats and Oceania holds 0.5 seats. The fifth place in Asia will compete with the first place in Oceania for a final seat.
The quota allocation is determined by the football development level of each continent and the results of the last Cup, and at the same time, we should consider promoting the development of underdeveloped football areas (Central and North America, Asia, Africa and Oceania).
The changes in the football World Cup finals are as follows:
1986-1994:1986 The World Cup in Mexico has once again resumed the competition system before 1974, but the difference is that there is an additional elimination stage. Twenty-four teams were divided into six groups. The top two teams in each group and the four teams with the best results advanced to the top 16 with the third place, and then the elimination tournament began. After the quarter-finals, quarter-finals, semi-finals and finals, the final champion was decided. 1990 World Cup in Italy and 1994 World Cup in America all followed this system.

From 1998, the number of teams participating in the World Cup in France 1998 increased to 32, and the competition system was slightly adjusted on the basis of the previous three sessions: 32 teams were divided into eight groups for single round robin, and the top two teams in each group entered the previous 16, and then the competition process was exactly the same as the previous three sessions.
The competition system of 20 10 World Cup in South Africa is the same as before. The 32 teams are divided into four grades according to the world ranking, and then divided into eight groups, with each team playing three games in the group match. Then the top two with more points appeared, and the last two were eliminated. Next is the pre-16 knockout, cross-elimination, group A first against group B second, and so on until the champion is produced.
Question: On the premise that the current competition rules remain unchanged, build your model to solve the following problems.
(1) Is the allocation of places for participating in the World Cup in all continents reasonable at present? If you think it is unreasonable, how can you arrange it reasonably? No matter what kind of distribution scheme, we must ensure that the quality or excitement of the game will not be greatly affected, so as to ensure that the attraction will not be significantly reduced.
(2) Due to the arrangement of the competition system, strong teams are often eliminated prematurely in the competition, which means that the strength of the team entering the next round of competition may not be stronger than that of the eliminated team. In order to minimize this situation, considering the minimum change of competition time and athletes' exercise amount, the competition system is arranged and its rationality is explained.
