Chapter 176 (1/2)
The silence of Cheng Yi's eyes is just staring at the teacher's right hand.
4:0！
Their island team, now, they have no way out.
The last game, the island team must win.
Otherwise, he will be abused by the Chinese team 5:0!
Once this happens, they will lose face.
As captain of the island team, Hayao Hirano may be OK for the time being. But once back home, I will be forced to film every day.
This is not the life Hirano wants. He has been tired of filming life, indulged in learning, unable to extricate himself!
”Mr. pingye, come on! Defeat the great demon of China All the island audiences were shouting in their hearts.
Hirano fayo, is the island sent to participate in the six players, the strongest one. Therefore, the audience in the island also place great hopes on him.
They know that Hirano fayo's opponent is Cheng Nuo, the hexagon fighter!
But still They have great confidence in Hirano's strength.
”Let's take a look at the two contestants' challenge.”
Mr. Jiang motioned for everyone to look at the big screen.
On the big screen, the screen flashed, and the five characters ”Tyson polygon” slowly emerged from the screen.
That's right. The name of the project that Cheng Nuo and keno are challenging is called ”Tyson polygon”!
Tyson polygon, a climatologist A. h. Thiessen, proposed a method to calculate the average rainfall according to the rainfall of discrete weather stations.
It's not that hard to build it.
In short, firstly, a discrete point is selected as the target point, and then the discrete point is connected with the surrounding discrete points to form one triangle after another to form a triangular network.
Let the discrete point be o. Find out a triangle with o as its vertex and set it as a; take another vertex of triangle a other than O and set it as a, then another vertex can also be found, that is, f; then the next triangle must have an edge of of of, that is, triangle f; if the other vertex of triangle f is e, then the next triangle has OE as its edge; repeat this until returning to OA edge.
The center of circumscribed circle of each triangle with the discrete point as the fixed point is calculated and connected.
In this way, the triangle formed is called Tyson polygon. If expressed by formula, it is √∑ (si-s) ^ 2n, (n = 1, 2, 3,...)
Take chestnuts ~ ~
the water cube in Kyoto is designed according to the principle of Tyson polygon.
The rules for the two players are as follows.
Two spheres, each with 5000 discrete points.
Every sphere has 5000 discrete points, and every discrete point can form a Tyson polygon, which is 5000 Tyson polygons in total.
Another sphere, also 5000 Tyson polygons.
In the total of 10000 Tyson polygons, there are only two Tyson polygons, exactly the same!
What the players need to do is to find out the two identical Tyson polygons in the shortest time and press the responder!
One point is added for correct answer and one point is added for wrong answer.
There are three games in all, and the first two points win.
This challenge project, at first glance, seems very simple. It is the upgrade version of ”find different” that we usually play. Find the same
However, in fact, this challenge is the most difficult one in the five matches between China and Taiwan today!
The comprehensive strength of the players is a great consideration.
Calculation, memory, space, reasoning, creativity, observation, six abilities are indispensable.
