Flower City, Jiashi Professional E-sports Club.

In a large conference room specially organized, 128 professional players from the club's virtual reality game branch gathered together, each holding a notebook and a pen, sitting neatly under the stage.

At the front of the conference room, next to the huge white board for the meeting, there were two people standing, one was an old man with white hair, and the other was Minister Zhao from the virtual reality game branch.

Minister Zhao suppressed his hand, suppressed the noise in the conference room, and then introduced: "This is Professor Xin, the former director of the Department of Mathematics of Huacheng University. This time he was hired by the club to teach everyone! Let us applaud and welcome him!"

Immediately, there was warm applause in the conference room.

"Okay, I won't say much if you don't want to say anything else. Everyone should study hard! Your academic performance will directly determine whether you can enter the list of key personnel training in the club!" After that, Minister Zhao retreated and completely gave up the podium to Professor Xin.

Although Professor Xin has a silver hair, he is energetic and speaks with a strong spirit, and does not look old at all: "My name is Xin Bin. I was invited this time to teach everyone a science, which is called game theory!"

He wrote the three words "game theory" on the whiteboard next to him, and then continued: "Okay, let's start teaching officially."

The club's list of key personnel training personnel is not so easy to enter. It means that the club spends tens of millions of dollars to raise your superpower level to level five or even higher, and mobilize other members to provide unconditional assistance in the official competition, plus hundreds of logistics support staff and public opinion propaganda resources... Even if a very demanding contract must be signed, it is enough to make 123 of them compete for the slaughter.

So, when the professor started his lecture, everyone opened their notebook and began to record it carefully.

Professor Xin also began to explain seriously, just like his past few decades: "What is game theory? Game theory, also known as countermeasure theory, is a branch of modern mathematics and an important subject in operations research. There are many majors in universities that need to learn this science, such as economics, securities, finance, politics, and even military strategy, which all require this game theory."

"What is its specific manifestation? Specifically, it is to use mathematical methods to deal with or predict certain phenomena or problems with struggle or competitive elements and solve them. Does it sound very complicated? It is difficult to understand? In fact, it is not difficult to understand, because this method is often used in our lives. At that time, we called it trade-offs."

"For example, if you and your girlfriend get off work in the evening and decide what to eat, you have three choices, one is a high-end Western restaurant far away from home, one is a Chinese fast food restaurant closer to home, and the other is to go home to cook instant noodles. At this time, your girlfriend suggests to eat a high-end Western restaurant. If you want to eat a Chinese fast food restaurant, how should you choose?"

Professor Xin wrote on the whiteboard, the horizontal rows are "Western restaurant", "fast restaurant", "boil instant noodles", and the vertical rows are "girlfriend" and "me".

Then he continued: "If you go to a Western restaurant, your girlfriend's satisfaction will be 100, and your satisfaction will be 50."

He wrote two numbers 100 and 50 under the "Western Restaurant" and next to "Girlfriend" and "Me".

"If you go to a fast restaurant, your girlfriend's satisfaction is still 50, and your satisfaction is also 50. If you go home to cook instant noodles, both of them will be 0."

Professor Xin said while writing the corresponding numbers under "fast restaurant" and "boiled instant noodles".

Finally, he concluded: "According to the addition, it is easy to see that going to a Western restaurant is 150, going to a fast restaurant is 100, and going home is 0, so you should take your girlfriend to a Western restaurant!"

As soon as he finished speaking, someone immediately refuted the audience: "Professor, what you said is wrong. I want to go to a fast restaurant. Since I have achieved my goal, my satisfaction should be 100. How could it be 50?"

"Of course it's 50. An unhappy girlfriend sits opposite you for dinner. Do you want 100?" Professor Xin shrugged.

"Then I spent a lot of money to go to a Western restaurant. Why do I have a satisfaction rate of 50?" Someone said he was puzzled: "It shouldn't be 0?"

"I said from the beginning that it was a Western restaurant far away from home, and I had dinner. After dinner, it was getting late, and my girlfriend was quite satisfied with you. Do you think they would go back to their own houses at that time?" Professor Xin smiled and said, "You said, how satisfied are you when you eat? Is there anything wrong with 50?"

"No problem!" The man sat down with convincing thoughtfully.

After giving an example, Professor Xin put down his pen and continued: "This is game theory, which is to convert each element in an event into numbers, and then use mathematical calculations and analysis to make the most rational and correct response. This response has nothing to do with good or bad, but it is the best for the whole!"

"For example, if you trade stocks, you expect a stock you have to fall, but the capital of this stock has not been recovered yet, so should you cut your liabilities? If you master the game theory, you can calculate the data you can collect by the expected decline, the capital invested, the level of your own capital tolerance, the possibility of subsequent rises, etc., and draw the conclusion of whether to cut liabilities and sell."

"The same is true for you to play in that e-sports game. If a teammate is chased by the local area, you have to think about whether he can be rescued, how much time it will take to save him, what benefits does it take for me to hold his opponent, what will the loss of this teammate have to affect the next game... and so on, we will finally come to the conclusion whether to save him!"

"Simply put, it is to remove the emotional and impulsive part of your heart, return to rationality, use your brain more, and make the most correct choice! Even if this choice is a bit ridiculous and difficult to understand, as long as the number you calculated is correct, then do it for me! Do it meticulously!"

"I have also watched some of your e-sports competitions before coming. In fact, in many cases, your competitions are similar to those of war. They are all intrigues, hiding your intentions, deceiving your opponents, and finally winning. What I teach here is the way to prevent you from being deceived, because..."
