Speaking of the cost of programming during this period? It can only be said that there is no one uniform standard.

However, in this set of hedgehog system, due to the use of some empirical formulas of later big data, these are very advanced knowledge, and 100,000 yuan is still worth it. If you put it in Silicon Valley, it might sell for more than $100,000.

By the way, the concept of empirical formulas. It is some algorithmic formulas that have not been rigorously demonstrated, but have been summarized through experience.

Papers are not usually published, but there are some important ones, such as some famous conjectures. Maybe it's the experience gained after a long period of summarization, or maybe it's the flash of genius.

Therefore, the advance here does not arouse the suspicion of others. After all, no one dares to guarantee that there is no genius in this world? Is there no flash of inspiration in this world?

As for that stand-alone version? It's really not worth much. That's just for the uninitiated.

Whether it is the small program that implements the algorithm or the operation interface provided to the user, for a senior program ape like Li Yuan, it is just the homework of a primary school monk.

In other words, 100,000 yuan is just to buy those experience formulas.

But in this broken county in the hinterland, how can it be possible to give you so much money? They don't even understand computers, they can't understand the value of these things.

Therefore, Li Yuan's attitude is very clear - simply don't take money, just make a name for yourself.

If you mix in the Internet IT circle in the future, you can justifiably introduce yourself, this piggy system is what I did! That's worth more than just 100,000 yuan!

……

A few days later, Wang Quan took Li Yuan to the county seat and met the interested leader. The strange thing is that he is not the leader of the county bureau of this county, but the director of the Xibei County Bureau next door.

Director Luo's name is Luo Changfeng, he is in his early thirties, and he should be regarded as a young and promising cadre. After seeing Li Yuan, although he was a little surprised by Li Yuan's age, he quickly covered up the past and greeted with a spring breeze on his face: "Xiao Li, when I was an intern, Uncle Quan was the master who took me. So we're all a family, so don't be restrained here. ”

Wang Quan introduced it appropriately: "Yuanzi, Luo Ju is a top student of the Police University. At that time, he took the initiative to ask to go down to the grassroots level, which was a big news that caused a sensation in the entire city bureau. ”

Li Yuan understands in seconds. A character like Luo Changfeng, a college student who takes the initiative to ask for the grassroots, either has a deep background or has ideals and wants to make a difference. Considering that he will be promoted to the head of the county bureau in about ten years, it should be both.

In addition to Wang Quan, the accompanying guest, Luo Changfeng also brought his secretary this time. The secretary had already booked a restaurant box for them.

After a few glasses of wine, Luo Changfeng belongs to the kind of person with high emotional intelligence, and Li Yuan is also very high in interpersonal communication. At least the first impression was good.

"Yuanzi, can you introduce your hedgehog system?" Luo Changfeng smiled and said, "I learned from the task force afterwards, your thing is quite magical?" ”

Li Yuan didn't hide it: "Brother Luo, it's actually not that accurate. ”

"Oh?"

"The whole uncle should know. In the case of the first video hall, our preparation in advance was to catch the boat, and the last thing we caught was not the sale of the boat, but the video of the ship. The follow-up case of selling the ship and the arrest of the thief are all implicated cases. So from the point of view of the hedgehog system, this time it should be regarded as a failure of prediction. The second underground casino case, although it was not wrong, but the probability of ranking two to ten results, if the police station to arrest it, maybe there will be gains. This can only mean that the sample of data is accurate, or that the clues provided are accurate. I really want to say that if there is no hedgehog system, according to the situation grasped by the police station, it can actually be caught without leaving the ......."

"What about the cattle theft?"

"The cattle theft case is the original foundation that was laid well. Here I want to say that those criminal police officers are indeed experienced and have a solid style. It was that group of thieves who took advantage of the blind spots in their thinking, didn't expect it for a while, and took advantage of the loopholes for a while. And my pig system is to eliminate all the impossibilities, and what remains in the end is the greatest possibility. ”

This famous quote of a dead elementary school student made Luo Changfeng laugh. He obviously relaxed a lot, which shows that Li Yuan is still a scientific person, and he is not a charlatan.

"Yuanzi, according to your statement, the success rate of the hedgehog system is not high?"

"I've done incomplete statistics, and it should be around 20%." Li Yuan continued to add, "Brother Luo, this is an auxiliary tool, and it can't decide to solve the case!" ”

Luo Changfeng nodded, thoughtful. In fact, when encountering a major case, it is quite worthwhile to increase the probability by 1%.

"So is there this set of technology abroad?" Luo Changfeng asked with a smile.

Li Yuan understood that Luo Changfeng was beginning to be moved. Maybe he just wanted to know about it before, but now he really wants this hedgehog system. In this era, catching up with the international advanced level is a panacea!

"The FBI and the CIA should have basic research projects. However, considering the laws of European and American countries, they dare not use the results when they have them. This involves the issue of personal privacy. In fact, Brother Luo, it is not the public security department that needs the hedgehog system the most, but the agency. ”

As for basic research in this area, European and American countries do have a deep foundation. But it has always been plagued by personal privacy issues, so it has not developed. It will not be until after the 911 incident that big data will be widely used in the judicial systems of Europe and the United States.

So in this regard, there is the possibility of overtaking in corners in China. In fact, this is also true. Later, in the field of big data, only China and the United States were left to dominate.

Luo Changfeng also understood what Li Yuan meant. He made a look, and the secretary understood, and led Wang Quan to the outside of the box to smoke a cigarette.

"Yuanzi, this thing should be very useful, but it can't chill the people who do specific things. If I understand correctly, a project like this can be as big as infinity. It is completely possible to set up a project in the department, or even in the ministry? ”

Li Yuan nodded, the importance of this project, not to mention Li Yuan personally, even Luo Changfeng, the director of the county bureau, can't reach it. But is it just for nothing to make a wedding dress for someone else? At the very least, we need to get some benefits, right?

"Brother Luo, your police university should have intelligence analysis, and your Ministry of Public Security also has a computer research institute. Can you jointly establish a project with us here, at least you can get a pilot unit for the city bureau and the county bureau? I can provide technical support and hand over all the original materials. I just want a right of authorship. You can also find a way to get into the project team. The project team needs at least a front-line case-handling technical expert at the grassroots level, right? If there are still a few papers in the future, we won't consider the corresponding author and a work, but it's not too much to give a low-ranking author, right? ”
