"Quanbo."

"Yuanzi, are you here? Still with fish? ”

"We just have a lot of fish there. If you can't finish eating at home, give everyone a point. ”

"Huh. Then you have a heart. First of all, I would like to introduce you to these colleagues. ”

“……”

After arriving at the township police station, it was indeed withered. In addition to Wang Quan, the deputy director, there is only a male policeman in his forties named Liu Meng, and a female policeman in his thirties named Liu Yanyan. In addition, with Li Yuan, a newcomer, there are only five joint defense members.

Since it is necessary to ensure that they are on duty at night, there is actually only one joint defense team member during the day today. He lives in Xiashan Township and is named Zhao Kang.

The conditions at the police station are quite poor. There is no motor vehicle at all, and you have to rely on two legs to go out. There were a few bicycles here, but not the turn of the joint defense team. In particular, the joint defense team did not have a uniform at all, so they were issued with a red armband, which felt particularly irregular at first glance.

But then again, the range of activities of the joint defense team is around the township government, and all the roars can be heard, and there is no need for transportation.

During the morning patrol, Zhao Dang took the initiative to introduce his experience to Li Yuan: "Yuanzi, now our biggest task is to maintain stability. Let's hope nothing big happens. Let them know that we are patrolling, which can give the police station a face. It's just a circle every day. We don't need more, we can't take care of more. ”

Li Yuan understood in seconds: "Just be a good scarecrow?" ”

"Haha! You are really literate and summarize it very incisively. ”

"And what if something big happens?"

"If there is a big case, notify the criminal squad. Our police station generally does not deal with it. The most troublesome thing is petty theft. Just like the other day when they rushed to the market, it seems that they know that there is a shortage of manpower here, and there are a lot of three hands on the road. ”

"Brother Dare, are there really so many thieves now?" Li Yuan took the initiative to salute a cigarette.

Zhao Dangmei took a sip: "What day is not much for thieves?" The key is that we must be able to control the field and make them dare not do it. In fact, the people at the police station, as well as those habitual thieves, are very familiar with each other. We are on the surface, and there are plainclothes anti-pickpocketing police in the bureau in secret. However, the current situation is known to be fundamentally uncontrollable on the surface. A few days ago, there were four reports in Daji, and there was a lot of uproar, and finally even the township chief went to the police station to pick up eggplants. It's very shameless. But what can Lao Wang do? ”

Li Yuan basically understood what he had to do. It is nothing more than a patrol in the morning to deter thieves on market days. Other times, obey the arrangements of the police station.

To tell the truth, although it is a bit of a duck to put on the shelves, in his heart, Li Yuan is still a little eager to try.

Even in the previous life, there was no experience at the police station, it seemed quite mysterious, and it seemed that all the people in it were detectives. But I never thought that I wanted to be a good scarecrow?

In fact, the work at the police station is more boring than expected. The civilian police also have some window affairs to handle. In addition to being on standby, the joint defense team is on standby.

In this era, fights and disputes on the street will not be reported at all, and no one will go to the police, and they will generally negotiate and resolve them by themselves. Family disputes do not go to the police, it is a matter for community cadres or village cadres.

After noon, it hurt to sit in the police station. Fortunately, Zhao Dare smiled and was relieved: "Yuanzi, our work is like this." Idle when idle, busy when busy. I'm going to take a nap first, maybe it's the middle of the night? ”

Did you know that was the case? You should bring those reference books with you, so that you can take the time to study the soft test and English.

Slowly, Li Yuan recalled the "Programming Basics" he reviewed a few days ago, and suddenly remembered big data, and in his previous life, there was a project team topic - big data to catch thieves.

It should be said that the subject was very funny, and it has since become one of the classic jokes in the industry.

It's not that big data catches thieves without scientific basis. Through big data, the behavior trajectory of thieves can be studied, and through the three key points of high-incidence areas of theft, the frequency of thieves, and the habitual places where stolen goods are sold, these three key points can be analyzed, and prevention, arrest and solving cases can be carried out purposefully.

Sounds great, right? But...... The world's surveillance network is almost free of thieves in the world? Who still takes off their pants and farts and uses big data to catch thieves?

In the end, the project team cried and fainted in the toilet.

But it's not a project now, Li Yuan is indeed a little itchy. Anyway, being idle is idle, so let's design a big data algorithm to catch thieves on paper!

Now there are no computers around, and there are not so many programming apes, it is impossible to write a complete program. Let's draw the most basic logical structure diagram. If you can't calculate it exactly, then use fuzzy math to calculate an approximate value. As for not having a big data sample? That's the theoretical calculation, it doesn't matter if you don't have a sample.

No one thinks this thing can catch thieves, right?

Li Yuan actually regarded this as an intellectual game, which was similar to playing a Rubik's Cube. After more than two hours, he finally filled four sheets of paper and stretched out contentedly.

"Yuanzi, what did you write? I see you've been busy for a while. Zhao Kang's voice suddenly came from behind him. He looked at the sheets of paper curiously, and his head was dizzy when he looked at the structural diagrams and mathematical formulas on them.

"Oh, this is an assistant program for catching thieves, and it is used on the computer."

"Can a computer catch a thief? That's a high-end thing. Zhao Dang obviously didn't believe it.

Li Yuan didn't want to explain too much. The concept of big data is too advanced, and Zhao Kang is still a complete layman.

"Brother Kang, I'm learning computer programming, and I made this program out of boredom. You just treat him as an exercise. There is no guarantee that it will be done right. ”

"Do the exercises? That's fine. Zhao Kang also came to be interested. Now the police are busy, and he is also idle, "Then let's try it, see your ...... That ......"

"Computer programs."

"Yes, yes. The computer program is right. ”

Li Yuan is funny in his heart, only ghosts are there when he is right. There is no computer programming here, there is no computer to run, just use paper and pen to simply calculate on paper, that error can be imagined, how can it be of practical value?

Anyway, it's just killing time, and the two of them start talking nonsense.

Don't say it, Zhao Kang is quite familiar with the news on the local road. What are the habitual thieves? What are the places where the stolen goods are sold? Their stealing habits, gangs or lone thieves? Do you prefer to touch your bag or burglary? ……

Li Yuan filled those samples into the algorithm and calculated the results. Final accuracy...... Not even 20%. And many of the results are unbelievable?

Seeing those rather absurd results, the two laughed again and again, and the laughter was endless......
