It's time to get off work. Tonight, it was the turn of the male policeman Liu Meng to rest, and the female policeman Liu Yanyan stayed on duty. Of course, Wang Quan also stayed in the institute 24 hours a day. It is estimated that if the cattle thief is not caught, the old policeman will not be able to return home.

But there are also advantages to having a policewoman, at least she can cook, and everyone can have a hot dinner.

Waiting for Liu Yanyan to cook dinner, taking advantage of this rare moment of rest, Wang Quan also came over to send a circle of cigarettes, and several people were immortal together: "What fun thing did you just say?" Laughter so loud? ”

"Wangsuo, Yuanzi has made a program, saying that he can help catch the thief. It's ......"

Zhao Dang talked about some of the absurd results of big data catching thieves, which was just a joke.

In fact, machine language and basic mathematics are cold and emotionless, and sometimes the results they come up with will completely violate human common sense.

For example, on a football field, what is the probability that two or more players with 22 players and 3 referees will have the same birthday?

The answer is more than 50%.

This is a typical probabilistic trap, and casinos rely on this to cheat money.

And then there is gender selection, in addition to men and women, there are also "other gender" options? (This is an early programming bug, and later database software makes up for this vulnerability)

Of course, later there were more than sixty gender selections on European and American websites? Those human rights organizations have indeed been crooked. But now, such a classification is rather ridiculous.

Regarding Zhao Kang's good-natured jokes, Li Yuan didn't have too many thoughts.

This program is not even a prototype. Add to that the fact that there is no computer-aided arithmetic at all, and the error is staggering. So it's quite normal to come up with some ridiculous results.

Unexpectedly, Wang Quan's focus was not here. He laughed and said, "Actually, this is okay, huh?" With a 20% chance of success, that's already a lot of money. ”

Li Yuan hurriedly explained with a smile that he couldn't mislead Wang Quan: "Uncle Quan, it's basically a reversal of cause and effect, so the success rate is higher." In addition, the trend is indicated, but it is not possible to clearly indicate which person, which place, and which case, so there is almost no practicality. ”

Since Zhao Dang provided all the cases that had already been solved, using these cases as data samples and inferring them in turn would of course be easy to get the correct results.

And then there's that practicality. For example, if you know that a thief is touching a bag in the market, but you don't know when he stole it, and whose bag is he touching?

I know that a thief has come to the door to steal, but I only know that in these communities, but I can't know which one I went to?

So it can't be used to solve cases at all. To put it mildly, it's better to find a few more informants.

Regarding Li Yuan's explanation, Wang Quan nodded thoughtfully. He has been a policeman all his life and has a lot of work experience, so of course he can understand what Li Yuan said.

After a while, Liu Yanyan delivered several large bowls of spicy noodles: "Eat it while it's hot." Yuanzi, try my sister's craftsmanship. ”

Li Yuan also happened to be hungry. And this spicy noodles taste pure, and the smell makes people appetite. The soup is covered with a thick layer of spicy oil, garlic leaves, chopped green onions, and chives.

Seeing Li Yuan's joy, Zhao Dang smiled and said, "Yuanzi, eat more." I hope there is less work in the middle of the night, otherwise I will be hungry and panic. ”

Unexpectedly, Wang Quan suddenly said: "Who said it was okay in the middle of the night?" Prepare for action tonight. ”

"Huh? Wangsuo, haven't you heard anything about it? ”

"Hehe, didn't Yuanzi make that thing?"

"Huh? Wangsuo, you won't take it seriously, will you? Just take this unreliable thing to catch a thief? Zhao Dang was taken aback.

Wang Quan smiled and shook his head: "How can we catch thieves?" Who are you looking for in the middle of the night? ”

"What do you mean?"

"Yanyan is here today, let's go catch the boat (river crab alternative)." Wang Quan showed the smile of an old fox, "Yuanzi, you can catch thieves and boats, right?" ”

Li Yuan was already dumbfounded. Quanbo shouldn't have drunk too much, right? And Zhao Dang was not wrong at all, that thing was not reliable at all.

"Yes, yes. However, I would like to make it clear in advance that this procedure can only be used as a reference, and the accuracy of the reference is not very large. Li Yuan hurriedly reminded.

Wang Quan waved his hand indifferently: "You don't have to worry about the rest of the matter." I don't blame you if I can't catch it. As soon as the cattle thief was delayed, the indicators in this year's institute were nervous. I'm still thinking about generating a small three-wheeler for the institute before I retire. Alas! ”

During this period, many grassroots police stations had income-generating indicators for catching boats and gambling. Whether this policy was good or bad, it was a special situation at the time. There is a shortage of funds everywhere, and even the funds of the Public Security Bureau are very tight.

Now that Wang Quan had made a decision, several people began to prepare for the evening action.

At this time, two more joint defenders came. The five of them left only one person during the day, and they took turns on duty at night. Gather all on the market day. Therefore, Wang Quan still takes good care of Li Yuan.

However, Li Yuan was still confused. This is so unscientific! None of the paper programs that use computers actually participate in solving the case with real guns?

Sure enough, after entering the data sample and Li Yuan calculated the result, several people burst into laughter: "Video hall? How is it possible to video the hall? ”

Li Yuan was also very helpless: "Uncle Quan, this is a mechanical operation, and it can only be said that the probability of the video hall is the highest." ”

Zhao Dang looked disapproving: "I said Wangsuo, this is too unreliable, right?" If we really want to catch the boat, it is more likely that we will still be in second place. ”

This time, even Liu Yanyan supported Zhao Kang's statement: "Wang Suo, this is obviously impossible. The video hall was opened in the original movie theater. In this public, how should men and women trade? ”

Another member of the joint defense team reminded: "The Lin family brothers who opened the video hall heard that there are people in their county. I haven't heard of any violations of law and discipline in them. At most, pirated videotapes will be released, and even the Cultural Affairs Bureau will not care about this kind of thing. ”

Hearing everyone's objections, Wang Quan grinned easily: "Anyway, the town is not big, and it doesn't take much effort to turn around." I went to the video hall and checked it. If not, let's go to the cow widow's house. ”

Li Yuan had vaguely sensed that in fact, even Wang Quan was quite skeptical of such a result. The reason why he did this was nothing more than that he was supporting himself, the kind of concern that the elders care about the juniors, for fear that Li Yuan would lose face in front of outsiders.

"Stop talking nonsense." Wang Quan clapped his hands, "All ready!" Leave on time at half past nine in the evening! ”

"Yes!" The other people looked at each other, with helpless expressions, and agreed weakly.

……

By evening, the town was completely dark. In the faint moonlight, several people with equipment and flashlights rushed to the direction of the video hall together......
