Datang: I am the prince of salted fish, I impeach Li Er at the beginning

Chapter 71 I understand, but I don't understand

"Then, under the premise of excluding other conditions, the Nash equilibrium comes out."

"Both A and B jointly choose the answer that is most unfavorable to them. This is the Nash equilibrium."

After clarifying this concept, Li Zhi said again: "The situation the prince is facing now is the Nash equilibrium. He has no better choice. He can only go this way. He doesn't even dare to hide this matter. It’s a Nash equilibrium.”

Cui Zhiwen seemed to understand, but he probably understood what Li Zhi wanted to express.

"The prince was forced into a corner, just like the two prisoners. He had no other choice but to betray Li Yuanchang, right?"

"No!" Li Zhi shook his head and denied: "You can only say that he has no better choice, but you can't say that he has no other way to go. The Nash equilibrium is always optional, and he always has other ways to go."

"For example?" Cui Zhiwen frowned and asked, he felt that he understood, but he didn't understand.

After talking for a long time, everything he just understood was overthrown by Li Zhi when he turned around.

Cui Zhiwen was puzzled as to what the King of Jin wanted to say.

At this moment, he saw Li Zhi smiled and replied casually: "For example, the prince can choose to follow Li Yuanchang on the road of no return, or he can choose to withdraw from the competition for the reserve position. This is a road. In fact, there are options, but he is unwilling to choose."

"Just like the two prisoners in the prisoner's dilemma, they both know what the best strategy is, but they are unwilling to choose."

"Because that path is extremely unfavorable to themselves, they chose the Nash equilibrium."

"Like I told you before, it's their own choice, not the Nash equilibrium coming to them."

"Do you understand the concept?"

Cui Zhiwen was thoughtful: "So, the prince forced himself into a Nash equilibrium?"

"It can be said that." Li Zhi smiled slightly, "But you can also say that I forced him into the Nash equilibrium."

When Cui Zhiwen heard this, his head hurt a little.

This sounds too convoluted.

He could understand what Li Zhi said: I forced him into the Nash equilibrium.

But what he couldn't understand was why the prince forced himself into a Nash equilibrium.

Looking at what Jin Wang Li Zhi did during this period, he was basically cutting off the prince's wings.

The first is Du He, Du He is the leader of the palace guard, Li Zhi drove Du He out of this position.

And this also meant that the prince lost the possibility of controlling the palace.

After that, Li Zhi drove Hou Junji out of the court.

Hou Junji was the general of the right guard and the commander of one of the sixteen guards.

Originally, the prince had the opportunity to control the military power in the capital. Even if it was just a part, he could do many things.

However, Hou Junji collapsed.

This also means that the prince lost the possibility of controlling the military power in the capital.

In other words, when things got here, even if the prince wanted to launch a coup, it would be impossible.

So far, the prince has lost his choice.

He can only hope that he will not make mistakes in order to keep the crown prince, other than that, he has no choice.

Thinking about this, Cui Zhiwen has completely understood why the prince chose to cooperate with Li Zhi.

Because the prince has no choice.

It's just... the problem now has become that Cui Zhiwen wants to thoroughly understand the concept of "game".

And if he wanted to understand this theory, he had to understand every word Li Zhi said.

Cui Zhiwen felt a headache from the overly profound theory, no matter how he tried to get around, he couldn't get around that hurdle.

Seeing Cui Zhiwen's painful appearance, Li Zhi tapped on the table lightly.

Cui Zhiwen was attracted by the sudden voice, and looked at him suspiciously.

Li Zhi smiled lightly and opened his mouth.

"Remember the price war between Yuzhuxuan and Qingyanglou a few days ago?"

Cui Zhiwen's thoughts were mobilized, and he nodded with a dull face: "I remember, it was Qingyanglou that first adjusted the price of tea products, and Yuzhuxuan was forced to adjust the price together. In the end, the two teahouses fell into an unsustainable situation. This incident caused a stir in the capital."

"Yes! This is another Nash equilibrium!" Li Zhi gave an affirmative answer, and explained: "Qingyanglou always holds the best game strategy, that is, their price, which is always higher than Yuzhuxuan is a class lower."

"Yuzhuxuan has no choice, he has to adjust the price together, otherwise Yuzhuxuan will go bankrupt first."

"What Qingyang Tower never expected was Yu Zhuxuan's choice later."

"When Qingyanglou felt the same and didn't want to continue to lower the price, Yuzhuxuan made a move."

"This time it's Yu Zhuxuan's turn to control the best game strategy, forcing Qingyanglou to fight."

"After going back and forth, the two teahouses are on the verge of closing down."

"Look, this is also a Nash equilibrium."

Having said that, Li Zhi asked: "Do you know why things have developed to this point?"

Cui Zhiwen thought for a while, and replied: "Qingyanglou is too greedy, he forced Yuzhuxuan into a corner, forcing Yuzhuxuan to die with Qingyanglou."

"Then do you know how to escape from this predicament?" Li Zhi asked again.

Cui Zhiwen didn't answer this question. He thought for a while and said, "Prince Jin, do you want to say that it was the Crown Prince who forced you into a corner first, and that's why you were forced to fight back?"

Li Zhi covered his face. Hearing these words, he really wanted to punch Cui Zhiwen on the forehead.

"What are you thinking? When did I say that I was forced to fight back?"

Hearing this, Cui Zhiwen said in a daze, "Then what exactly do you want to say?"

Li Zhi sighed softly, and waved his hands weakly at him: "Can you answer me, the question I asked before? How should the two teahouses escape from the predicament."

Cui Zhiwen shook his head: "I can't find a way, this is the same as the prisoner's dilemma, there is no answer."

"Look! This is where you don't understand well!" Li Zhi said speechlessly: "You forgot that the environment has changed and the communication channel has been opened. To solve this problem, you have to communicate with the other party!"

"But... after such a long price war, can they still communicate?" Cui Zhiwen said unconvinced. He was still struggling with the problem of the two restaurants and was worried about this solution.

But in fact, Li Zhi has been talking about the problems between himself and the prince, and the two restaurants are just an analogy.

Li Zhi didn't speak, just looked at Cui Zhiwen quietly without saying a word.

After being stared at by him for a while, Cui Zhiwen suddenly realized.
