Doomsday Paradise

Chapter 1957 Mimetic gift packages are more organized than Lin Sanjiu
Sometimes being able to think things through clearly does not mean being able to explain things clearly—not to mention that when Lin Sanjiu broke the situation, many thoughts and analyzes were actually just a flash of thought in the depths of his mind, still staying at the level of vagueness and "thinking activities" In fact, it is far from being able to put it into language.

In order to clarify and express all her thoughts, she needs to use mimicry instead.

The long-lost Ji Shanqing, who almost made her feel strange, was as thin as mist, and also like the last signal; compared with many years ago, when he mimicked Ji Shanqing now, no matter the degree of clarity or stability It's far worse than when she just walked with him.

When she was out of sight and away, her relatives and friends seemed to keep changing and going away.

"This skill is quite interesting," the female homeowner looked at her, didn't ask anything but seemed to understand, and murmured, "We have to be more careful in the future."

The male intermediary moved two stools from nowhere, and got ready to listen to Lin Sanjiu's speech; it was obviously a replica creature, but it was still very "human" in the details.

"The information given in room 101 is very important. It provides the key prerequisite for whether a person can leave the instance." Lin Sanjiu said, "Ignoring the exit, I need to verify two points. The first is 'every resident There are both truths and lies in what you say, and the second is that there are 'truth intermediaries' and 'false intermediaries'."

It stands to reason that this key premise should be the first to get it. Room 101 is also at the starting point of the dungeon, but Lin Sanjiu didn't knock on the door of room 101 until the middle of the dungeon.

"Is it because I haven't heard the introduction to dungeon rules, so I don't know where to start?" she asked, "Isn't it?"

"No." The female homeowner crossed her legs and said, "On average, more than half of ten people will go to the depths of the corridor first to see the situation. Many people will choose to walk the entire building first before talking about it." .When the safety ahead is unknown, few people will immediately knock on the first door around them.”

...That's why the dungeon stuffed the most critical information into 101.

"The traps you specially set for evolutionists are not limited to this one. And the more intelligent, prudent and thoughtful people are, the easier it is to be trapped in the trap and unable to get out."

The landlady smiled.

"Even if we got the key information from Room 101 at the beginning," Lin Sanjiu said flatly, "After walking through the apartment, the Evolved One will find that he can't tell the truth of the information in Room 101 at all."

When she just listened to the information about Room 101, she felt that the premise that "every resident speaks a truth or a lie" must be true.

Because if this sentence is a lie, then there are two inferences: first, the resident is only telling the truth, which is contradictory to the premise and impossible; second, the resident is only telling lies.

But at that time, it seemed that the middle-aged woman in 103 said that "the residents will deceive people into the house, and you can't get out after entering the house", which seemed to be true; if 103 told the truth, then the possibility "two" is not true, There are both truths and lies in what the residents say." That is true.

Isn't this progress?She was very happy at that time - until Lin Sanjiu came to Room 205.

"The man who asked for help told me that I could still come out when I entered the apartment of the resident, and the resident was just pretending to trick me into it." She couldn't help laughing bitterly, "In this way, the basis of this inference, that is, the '103 middle-aged Women tell the truth' and that's overturned."

Now, it's complicated.

When she found that the inference had been overturned, she was unwilling to think about it again, only to find that her initial deduction steps were actually too simple and did not include all possibilities.

Assuming that the premise of "every resident's words are true and false" is false, then she is not faced with two possibilities, but six possibilities:

[-]. Residents only tell the truth; [-]. Residents only tell lies; [-]. Some people only tell the truth, while others only tell lies; False words, there are truths and falsehoods in some people's words; Sixth, some people only tell the truth, some only tell lies, and some people's words have both truth and falsehood.

"But the first three possibilities will soon be ruled out."

Even if Lin Sanjiu didn't activate the mimesis at that time, it only took her a few seconds: "It goes without saying that the first possibility is not true, and the second possibility is also not true, because some conditions are contradictory. For example, one person said that I entered the apartment of a resident. Then I couldn’t get out, and one person said that I could get out after entering the apartment, so it’s impossible to be false at the same time.”

The third possibility, also because of the college students in room 206, can be ruled out: he said that the house of 102 adult boys and children was an exit, and he already knew it was a lie through the leaks in the photos; and his warning to Lin Sanjiu, "Don't help Residents do daily chores", but it is true from her experience - no one has put forward contradictory conditions, and the apartment residents are indeed deliberately tricking her into helping with daily chores, which should be intentional.

"Actually, from an intuitive point of view, at this point, the condition that the residents say something is true or false, it seems to be true. But I am afraid that you are taking advantage of this to harm people, so I have to continue to dig deeper. Think about it."

"Wait, let me remember," the hostess took out her mobile phone from her trouser pocket and typed for a while. "Okay, you continue."

However, when this step was reached, Lin Sanjiu found that she couldn't go any further.

Because to falsify the fourth, she has to prove that someone is only telling lies; to falsify the fifth, she has to prove that someone is only telling the truth—in other words, she cannot rule out the fourth and fifth possibilities at the same time.

If she wanted to rule out the sixth possibility, she had to find out the truth and falsehood of each resident's statement; but she wanted to verify the premise in order to find out the trueness of the resident's information, but unexpectedly, she went around in circles and came back again.

"If the premise of 'the residents' words are true or false' is false," Lin Sanjiu said in a deep voice, "then I can only draw an ambiguous conclusion—the exit may be at 104 or at 205. Moreover, The odds are slim."

Further inferences are basically impossible: because almost every step of inference has new possibilities that she cannot completely rule out; if new possibilities cannot be ruled out, the only correct answer cannot be obtained.

"So, my subsequent analysis is all carried out under the condition that this premise is true."

If "the resident's words are either true or false" is true, then the two information points given by 102 adult boys and children have been proved to be false, then the point "truth intermediary and false intermediary" is true.

"And then?" the hostess asked urgently.

"From this, it can be confirmed that Xiao Xu, the agent, is a truth-telling agent." Lin Sanjiu explained, "This point will come in handy after a while."

The breaking point started from room 105.

After the woman in room 105 failed to deceive Lin Sanjiu, she told her that, first, rooms 106 and 107 are intermediaries; second, rooms 106 and 107 are real intermediaries.

If one of these two information points is true and the other 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 But it is possible to tell the truth, and it is also possible to tell lies.

If room 107 is a real agency, the deduction is very simple and smooth: room 202 is also a real agency, so it is concluded that room 207 is also a truth agency, and there is a hidden agency on the second floor, which must be a lie intermediary.

Considering that what 107 said "do not enter an apartment without an intermediary" is true, and what the intermediary Xiao Xu said "the exit is in an apartment with residents" is also true, so it is very simple, the exit must be "there are both intermediaries and Residents in the "apartment"—combined with the false intermediary hidden on the second floor, it is not difficult to find that only room 203 has two people inside it, which is Lin Sanjiu's only answer.

If 107 is a false intermediary, it will be a little more complicated: since 107 said that room 202 is an intermediary, then the woman in room 202 must be a resident, and if she is a resident, her words may be true or false; among the four information points she provided, The first and second points must be false.

If the third point is false, combined with the information that the agent Xiao Xu said that "there is more than one agent in this building", then it means that the number of agents on the second floor is neither 0 nor 2.If true, there are two intermediaries on the second floor.

The fourth point can’t be true—if the fourth point “the room in room 207 is an intermediary” is true, then the intermediary in room 207 is a truth-telling intermediary. As a truth-telling intermediary, he said that room 202 is also an intermediary, and 202 is a contradiction in the premise of the resident, so it cannot be true.

So the fourth point that the woman in room 202 said can only be a lie, that is, the house in room 207 is not an agent but a resident; the third point she said is the truth.

Therefore, it can be concluded that there are at least two hidden intermediaries on the second floor, and they are false intermediaries.

After deducting 202, 207, college students, and dog walkers, these two hidden false intermediaries can only exist in rooms 203 and 205.

If the intermediary in room 205 is a lie, when he said "my home is not an exit", it means "my home is an exit": this contradicts the real information given by the intermediary Xiao Xu - the exit only exists for the residents of this apartment In the room, and the intermediary is waiting for the client in this building.

In this way, only 203 is left.

If the "wife" of 203 lied about the intermediary, then what she said "she sold the house without an intermediary" was a lie, that is, "she used an intermediary to sell the house"-but she herself is an intermediary and not a resident, which creates a conflict of information, so The "husband" should be the intermediary of lies, and the "wife" is the resident.

The "wife" is a resident, so what she said can be true or false; among them, "sell the house without an intermediary" is false, and the other two can be true or false—after considering three possibilities, Lin Sanjiu found that , the exit is in room 203 with a two-thirds chance.

"While I can't rule out all other possibilities [-] percent,"

She said with a cold face, "But I think your dungeon is specially designed like this, isn't it? According to the information you gave, it is impossible to completely rule out all other possibilities, otherwise your information is too coincidental All in all, to come out, I have to choose the one with the highest probability after weighing it.”

After a few seconds, the hostess nodded.

"Yes," she put away her phone, and said, "An evolutionist told us about a psychological finding that when people face more choices and more possibilities, it is more difficult for them to make decisions. Judgment. It's really hard for me...do you have any way or suggestion to prevent the next person from coming out like you?"

"No."

"Don't forget, the condition we agreed on is that only if you cooperate with us, we will tell you the information you want..."

"No." Lin Sanjiu said coldly, "Even if there was, I wouldn't tell you."

"Then I can't help it, don't blame me for not being mean." The hostess shrugged her shoulders, suddenly raised her eyes behind Lin Sanjiu, and smiled. "Ah, there is no time. The next one to pick you up has already arrived."

　I'm really sorry everyone, I missed one or two clues in the clue sorting chapter, so I went back and added them quietly, but it shouldn't affect the deduction process (right).It can be seen that I really saved a lot of deduction process, for example, why if the premise is false, both 104 and 205 are very likely to be the exit - it would be too long to write this out, and finally get away with Lin Sanjiu The relationship is not too big, so I omitted the process and only put the conclusion.But if you are interested (you have nothing to do), you can try to deduce it, and I promise it can be deduced.

If you draw a picture, it will be much more intuitive and clear than text. I have drawn a lot of relationship diagrams. As a result, it is difficult to express in words, and the expression is particularly long-winded.I still can't express it, the first sentence at the beginning of this chapter is true...

Anyway, I won’t write this kind of dungeon anymore, I didn’t do anything for almost two days on the weekend, except for eating and sleeping, I was writing this chapter...

Merry Christmas to everyone!
