Huacheng, Jiashi professional e-sports club.

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

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

Minister Zhao pressed his hand and suppressed the noise in the conference room, and then introduced: "This is Professor Xin, the former chief professor of the Department of Mathematics of Huacheng University, who was hired by the club this time to teach everyone!" Let's welcome him with a round of applause! ”

Immediately, there was warm applause in the conference room.

"Okay, I won't say anything else, everyone study hard! Your academic performance will directly determine whether you can enter the list of key training personnel of the club! With that, Minister Zhao stepped back and gave up the podium to Professor Xin completely.

Although Professor Xin has silver hair, he is in good spirits, and his speech is full of energy, and he does not look old at all: "My name is Xin Bin, and I was invited here this time to teach you a science, which is called: Game Theory!" ”

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

The list of key cultivators in the club 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 official competitions, plus hundreds of logistics support personnel, public opinion and propaganda resources...... Even if a very demanding contract had to be signed, it would be enough for 123 of them to fight for their heads.

So, when the professor started to speak, everyone opened their notebooks and began to take notes carefully.

Professor Seng began to explain in earnest, as he has done for decades: "What is game theory? Game theory, also known as strategy theory, is a branch of modern mathematics and an important discipline of operations research. ”

So what exactly does it look like? Specifically, it is to use mathematical methods to deal with or predict certain phenomena or problems with struggle or competitive elements, and solve them. Doesn't that sound complicated? Incomprehensible? In fact, it is not difficult to understand him, because in our lives, we will often use this method, at that time, we called it trade-off. ”

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

Professor Xin wrote on the whiteboard, the horizontal row is "Western restaurant", "fast restaurant", "boiled instant noodles", and the vertical row is "girlfriend" and "me".

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

He wrote the numbers 100 and 50 respectively under the "Western Restaurant", next to "Girlfriend" and "I".

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

Professor Xin said as he wrote down the corresponding numbers under "fast food restaurants" and "boiled instant noodles".

In the end, he concluded: "According to the addition, it is easy to see that it is 150 to go to a western restaurant, 100 to a fast food restaurant, and 0 to go home to instant noodles, so you should take your girlfriend to a western restaurant!" ”

As soon as his words fell, someone in the audience immediately retorted: "Professor, what you said is not right, I want to go to a fast food restaurant, since I have achieved my goal, my satisfaction should be 100, how can it be 50?" ”

"Of course it's 50, an unhappy girlfriend sits across from you for dinner, and you still want 100?" Professor Shin shrugged.

"Then I went to a Western restaurant, I spent a lot of money, how can I still have a satisfaction of 50?" Someone else expressed puzzlement: "Shouldn't it be 0?" ”

"I said at the beginning, it's a Western restaurant far away from home, and it's dinner, at this time, it's not early, and your girlfriend is quite satisfied with you, do you say you'll go back to your home at that time?" Professor Xin smiled: "You say, what is your satisfaction when you eat?" Is there something wrong with 50? ”

"No problem!" The man sat down convincingly.

After giving an example, Professor Xin put down his pen and continued: "This is game theory, which is to convert the various elements of an event into numbers, and then use mathematical calculations and analysis to make the most rational and correct response, which is not good or bad, but for the whole, it is the best!" ”

"For example, if you speculate in stocks, you expect that a stock in your hand will fall, but the capital of this stock has not been recovered, so should you cut the meat? If you have mastered game theory, you can calculate the data that can be collected through the expected decline, the cost invested, the tolerance of your own funds, the possibility of rising later, etc., and draw a conclusion about whether to cut the meat and sell. ”

"It's the same with you playing that e-sports game, if a teammate is chased by a local person, then you have to think about whether you can save it, how much it costs to get out, how much time it takes, what is the benefit to me if my teammate hangs the opponent, and what is the impact of losing this teammate on the next game...... And so on, and finally came to the conclusion that you should save it or not! ”

To put it simply, it is to get rid of the emotional and impulsive part of your heart, return to reason, use your brain more, and make the most correct choice! Even if the choice is a little ridiculous and a little incomprehensible, as long as the number you calculated is correct, then do it for me! Do it meticulously! ”

"I've watched some of your e-sports matches before I came, in fact, in many cases, your games and battles are similar, it's all a process of deceiving yourself, hiding your intentions, deceiving your opponent, and finally winning, what I'm teaching here is how to keep you from being deceived, because ......"

"Your eyes will deceive you, your feelings will deceive you, your experience will deceive you, but ...... Math doesn't! ”
