Doomsday Wonderland Chapter 1951: Mimicry’s gift package is more organized than Lin Sanjiu
Sometimes being able to figure things out does not mean that you can explain things clearly - not to mention that when Lin Sanjiu broke the situation, many of his thoughts and analyzes were actually just flashes of thought in the depths of his mind, still remaining in the vague, "thinking activities" ” level, far from being able to be put into words.
In order to clarify all her thoughts and express them, she needed to use mimicry instead.
Ji Shanqing, who had not been seen for a long time, almost felt strange to her, was as thin as mist, and like the last signal; compared to many years ago, when she mimicked Ji Shanqing now, both in terms of clarity and stability The level was far less than when she just walked with him.
When she is out of sight or around, her relatives and friends seem to be constantly changing and moving away.
"This skill is quite interesting," the landlady looked at her and seemed to understand without asking anything. She murmured, "We have to be more careful in the future."
The male agent brought two stools from nowhere and was ready to listen to Lin Sanjiu's speech; he was obviously a copy of the creature, but he was still very "human" in every detail.
"The information given in Room 101 is crucial. It provides a key prerequisite for whether a person can leave the instance." Lin Sanjiu said, "Ignoring the exit, there are two points I need to verify. The first is' There are truths and lies in what every householder says, and the second thing is that there are 'truth intermediaries' and 'lie intermediaries'."
Logically speaking, this key premise should be the first to get it. Room 101 is also at the starting point of the dungeon, but Lin Sanjiu did not knock on the door of Room 101 until the middle of the dungeon.
"Is it because I haven't heard the introduction to the dungeon rules and don't know where to start?" she asked, "Isn't it?"
"No." The landlady crossed her legs and said: "On average, more than half of the ten people will walk deeper into the corridor first. Looking at the situation, many people will choose to clear the entire building first. Walk through it before talking. When the safety ahead is unknown, few people will immediately knock on the first door next to them."
...That’s why the copy stuffed the most critical information into 101.
"This is not the only trap you have specially set for evolvers. And the more intelligent, prudent and thoughtful a person is, the easier it is for him to be trapped in a trap and unable to get out."
The landlady smiled.
"Even if he got the key information from Room 101 at the beginning," Lin Sanjiu said flatly, "when walking through the apartment, the evolutionist will find that he can't tell whether the information in Room 101 is true or false."
When she just listened to the information about Room 101, she felt that the premise that "every resident's words are true or false" must be true.
Because if this sentence is a lie, then there are two inferences: first, the resident only tells the truth, which contradicts the premise and is impossible; second, the resident only tells lies.
But at that time, it seemed that the middle-aged woman 103 said that "the residents would trick people into entering the house, and they would not be able to get out". If 103 told the truth, then possibility "two" does not hold true. "There is truth and lies in what every resident says" is true.
Isn’t this progress? She was very excited at that time - until Lin Sanjiu came to room 205.
"The man who asked for help told me that I could still come out after entering the tenant's apartment, and the tenant was just pretending to trick me into getting in." She couldn't help but smile bitterly when she said this. "In this case, the basis of this inference is' 103 The fact that the middle-aged woman told the truth has been overturned."
This time, it’s complicated.
When she found that the inference had been overturned and reluctantly thought about it again, she realized that her initial inference step was actually too simple and did not include all possibilities.
Assuming that the premise "every householder says something true or false" is false, then she is not faced with two possibilities, but six possibilities:
First, the residents only tell the truth; second, the residents only tell lies; third, some people only tell the truth, and some only tell lies; fourth, some people only tell the truth, and some people's words contain both truth and lies; fifth, Some people only tell lies, and some people's words contain both truth and falsehood. 6. Some people only tell the truth, some people only tell lies, and some people's words contain both truth and falsehood.
"But the first three possibilities can be ruled out soon."
Even if Lin Sanjiu didn't activate mimicry at that time, it only took her a few seconds: "The first possibility goes without saying, and the second possibility is not valid because some conditions are contradictory. For example, a person said that I entered I couldn’t get out after entering the tenant’s apartment, and one person said that I could get out after entering the tenant’s apartment. It’s impossible to be false at the same time.”
The third possibility can also be ruled out because of the college students in Room 206: He said that the adult boy's house in Room 202 was the exit, which was already known to be a lie through the photo loophole; and his warning to Lin Sanjiu, "Don't help residents with daily chores" is true from her experience - no one put forward contradictory conditions, and the apartment residents were indeed deliberately trying to trick her into helping with daily chores, and there must be some intention.
"In fact, from an intuitive point of view, at this point, the condition that the residents' words are true or false seems to be true. But I am afraid that you are taking advantage of this to harm people, so I have to continue. Think a little deeper."
"Wait, let me write it down," the landlady took out her mobile phone from her trouser pocket and typed for a while. "Okay, you continue."
However, when she reached this step, Lin Sanjiu found that she could no longer eliminate it.
Because to falsify the fourth, she has to prove that someone only tells lies; to falsify the fifth, she has to prove that someone only tells the truth - in other words, she cannot rule out the fourth and fifth possibilities at the same time.
To rule out the sixth possibility, she had to find out the truth and falsehood of each resident's words one by one; but she wanted to prove the premise in order to find out the truth and falsehood of the resident's information. Unexpectedly, she went around in a circle and came back again. .
"If the premise of 'What residents say is true or false' is false," Lin Sanjiu said thoughtfully, "then I can only draw an ambiguous conclusion at most - the exit may be at 104 or 205 . Moreover, the possibility is still very small."
It is basically impossible to make further inferences: because almost every step of inference has new possibilities that she cannot completely rule out; if she cannot rule out new possibilities, she cannot obtain the only correct answer. .
"So, my subsequent analysis will be conducted under the condition that the premise is true."
If "what residents say is true or false" is true, then the two information points given by 102 adult boys have proven that the photos are fake, then the point of "truth intermediary and false intermediary" is true. Yes.
"What then?" the landlady asked urgingly.
"This can confirm that the agent Xiao Xu is a truthful agent." Lin Sanjiu explained, "This will be used in a while."
The breaking point begins in Room 105.
After the woman in room 105 failed to deceive Lin Sanjiu, she told her that first, rooms 106 and 107 were both agents; second, rooms 106 and 107 were both truthful agents.
One of these two information points is true and one is false. One of them must be true, otherwise there will be a logical contradiction. Then there are only two fake ones - judging from the words of the agent in Room 106, he is a fake agent.
107 It is possible to tell the truth as well as lies.
If Room 107 is a truth-telling agent, the inference is very simple and smooth: Room 202 is also a truth-telling agent, so it is concluded that Room 207 is also a truth-telling agent, and it is concluded that there is a hidden agent on the second floor, and it is certain It's a lie agency.
Considering that what 107 said "Don't enter an apartment without an agent" is true, and what agent Xiao Xu said "the exit is in an apartment where residents live" is also true, then it is very simple, the exit must be "at the same time" "In an apartment with an agent and residents - combined with the fake agent hidden on the second floor, it is not difficult to find that there is only room 203 for two people inside, which is Lin Sanjiu's only answer.
If 107 is a false agent, it is a little more complicated: Since 107 said that room 202 is an agent, then the woman in room 202 must be a resident, and her words may be true or false; the four pieces of information she provided Among the points, the first and second points must be false.
If the third point is false, combined with the information from the agent Xiao Xu that "there is more than one agent in this building," it means that there are agents on the second floor whose number is neither 0 nor 2. If it is true, there are two intermediaries on the second floor.
The fourth point cannot be true - if the fourth point "there is an agent in room 207" is true, then the agent in room 207 is the truth-telling agent. As a truth-telling agent, he said that the same is true in room 202. The intermediary contradicts the premise that 202 is a resident, so it cannot be established.
So the fourth point said by the woman in Room 202 can only be a lie, that is, the people in Room 207 are not agents but residents; the third point she said is the truth.
It can be concluded that there are at least two hidden intermediaries on the second floor, and they are false intermediaries.
After deducting numbers 202, 207, college students, and dog-walking women, these two hidden lying agents can only exist in rooms 203 and 205.
If Room 205 is a false agent, when he says "my home is not an exit", it means "my home is an exit": This is contradictory to the true information given by the agent Xiao Xu - the exit only exists in this house. In the residential room of the apartment, the agent is waiting for clients in this building.
In this way, only 203 are left.
If 203’s “wife” is a false agent ~IndoMTL.com~, then what she said about “selling the house without an agent” is a lie, that is, “she found an agent to sell the house” - but she is an agent and not a resident. There is an information conflict, so the "husband" should be the lie agent, and the "wife" is the resident.
The "wife" is a resident, so what she says can be true or false; among them, "selling the house without an intermediary" is a lie, and the other two can be true or false - after considering the three possibilities, Lin Sanjiu found that the exit was in Room 203 with a two-thirds probability.
"While I cannot 100% rule out all other possibilities,"
She said with a cold face, "But I think your copy is specifically designed this way, right? According to the information you gave, it is impossible to completely rule out all other possibilities, otherwise the information you gave will not be enough. What a coincidence. All in all, to come out, I have to choose the one with the highest probability after weighing it."
After a few seconds, the landlady nodded.
"Yes," she put away her phone and said, "An evolutionist once told us about a psychological discovery, which is that when people face more choices and more possibilities, they It’s getting harder and harder to judge. It’s really embarrassing for me... Do you have any methods or suggestions to prevent the next person from coming out like you?"
"No."
"Don't forget, the condition we agreed upon is that we will tell you the information you want only if you cooperate with us..."
"No." Lin Sanjiu said coldly, "Even if there is, I won't tell you."
"Then there's nothing I can do, but don't blame me for keeping my word." The landlady shrugged her shoulders, then suddenly raised her eyes behind Lin Sanjiu and smiled. "Ah, there's no time. The next one to pick you up has already arrived."
