Deng Da squinted his eyes and said, "How do you say the consensus?"

"For example, if we have something to do and need to have an interview, we will agree on the time and location of tomorrow's meeting in text messages. [】However, both of us are very precious, and we will only be present when we are sure that the other party can go.

You sent me a text message saying: Let's see you at Room 109, Jiangda Chemical Building at 10:00 tomorrow. However, it is common to send text messages. To be sure I learned this news, you added: Please reply if you receive it."

"Bah, I won't want to meet you." Deng Da spat, with a smile on his little face, obviously he also found it very interesting, and he couldn't help but accept Liu Chen's teaching method very much. This is not easy. But since he was a child, he has been annoyed by the teacher to talk nonsense on the podium and waste time. "Sorry, I know it's an example, you can continue to say it."

Liu Chen paused and continued, "After I received the message, I replied immediately: I have received it, and I will see you tomorrow at 10:00. However, I also have my own concerns: Didn't you go only after confirming that I'm going? If you don't receive my confirmation text message and don't attend, wouldn't you let me wait for a sermon? Therefore, I also attached a sentence: Please reply after receiving this confirmation message."

"It's so long-winded, okay, okay, I won't bother you anymore. I'm the most annoying and wasting time, sorry."

I have never seen such an impatient girl. Liu Chen continued: "After you receive the confirmation text message, you will naturally reply: you receive the confirmation message. But you have new concerns."

Deng Da rushed to say, "I would think that if Liu Chen did not receive my reply, he would be worried that I would not go because he did not receive his reply. Then would he stop going? To ensure that you received the reply, I also added at the end of the text message: Please reply when you receive it. This process continues, obviously endlessly."

"Smart, the result is that both of us have been confirming each other's information, but we have never reached such a consensus: we will all arrive at Room 109, Jiangda Chemical Building at 10:00 tomorrow."

"That's not simple. I'll just call you?"

"This is indeed the best solution to the above dilemma. What is the difference between making a phone call and sending a text message, which makes the two of us solve the problem in an instant? The main reason may be that making a phone call is online, while sending a text message is offline. When making a phone call, everyone can be sure that the other party is listening, and so on. Therefore, any words the two say will immediately become a consensus: not only I know, but I know you know, and I know you know I know..."

"Let's talk, hurry up and talk about the topic, I understand the consensus." Deng Da was very anxious and his eyes narrowed even tighter.

Liu Chen said directly: "The great wizard announced in public that [there is at least one blue eye on the island], which is to let everyone know this, and let everyone know this, and nest it infinitely like this. This message has become everyone's consensus, so what will happen?"

"Suppose there are only two blue eyes on the island. Both of them can see that the other party has blue eyes, so they all know that 'there is at least one blue eyes on the island'. However, since the mage did not show up, neither of them knows whether the other party knows whether the other party has blue eyes on the island. So, by the next day, the previous reasoning could not continue. Everyone would think in their hearts that the other party did not commit suicide because the other party did not know that 'there is blue eyes on the island'."

Oh, Deng Da suddenly realized and shouted, "So that's it." After saying that, he felt embarrassed and whispered: "You keep talking."

"Similarly, if there are three blue eyes on the island, then unless they all know and everyone knows that everyone knows that 'there are blue eyes on the island', the reasoning on the fourth day is not true. On the third day, someone will think that the two people did not commit suicide just because they didn't know that the other party also knew that 'there are blue eyes on the island'. Continue to expand to 100 blue eyes, you will find that 'know each other' must be nested 100 layers in order for all reasoning to proceed smoothly."

"In fact, the conditions of this topic are not complete enough. Everyone on the island knows the above conditions and rules very clearly, and should be changed to: the above conditions and rules are the consensus of everyone on the island, or: everyone on the island knows the above conditions and rules, and everyone knows that everyone knows, wait and see. If there is no such condition, the reasoning just now is not valid. For example, although everyone is infinitely smart, if everyone doesn't know that others are infinitely smart, or if everyone doesn't know that others are also infinitely smart, the reasoning will be stuck because of the idea of ​​'He didn't commit suicide last night just because he was too stupid and didn't come out'."

After hearing this, Deng Da opened his eyes for a moment, as if he understood.

Liu Chen continued: "In fact, it is difficult for the human brain to imagine the assumption of this question. Everyone has the ability to reason. If it is implemented using a computer program, it will be much clearer. It is equivalent to everyone's thinking in an infinite loop. The words said by the great master are breaking the interruption of everyone's infinite loop and will trigger a series of chain reactions."

Deng Da thought, "What is the result?"

She already has the answer, just to verify it.

"After the great master said that, on the 101st day, all blue eyes will find that they have blue eyes and commit suicide collectively. On the 102th day, the remaining 900 brown eyes will die because of blue eyes. Then we know that the color of their eyes will also commit suicide collectively. The final result is that the island will be completely extinct."

Deng Da knocked on his head, but he felt very swollen, but he was in a very good mood. "Ha, I can finally have a good night's sleep, so happy."

After saying this, there was no movement again.

Dr. Deng not only stayed on his mouth, but fell asleep immediately after saying that, and in a few seconds he entered a deep sleep. The little snoring was rhythmic, and the big big-framed glasses were still stuck in his eyes. The small face as big as a palm seemed smaller, the pale face was a little rosy, and there was a sweet smile on the corner of his mouth. The skin was very good, very much like the stingy little girl in the comics, kawaii.
