Chapter 533

"Which one of you has a cad on your computer?"

at this time.

Su Chen asked everyone.

CAD, which is a computer-aided design software, uses computers and their graphics equipment to help designers perform design work. In the design, it is usually necessary to use a computer to perform a large number of calculations, analyzes and comparisons on different schemes to determine the optimal scheme.

The architectural composition and engineering modeling on engineering drawings that you often see are made with CAD.

But what does Su Chen want this thing for?

Could it be that he really has a way to find the place of the murder? !

"I have it on my computer!"

A technician in his thirties raised his hand, "I downloaded it for learning before."

Su Chen strode over. The technicians hurriedly turned on the computer and let Su Chen operate it, while Ying Baisha and others gathered around to watch.

"Generally speaking, the radius of a person's life is actually not large. Most people spend most of their time within a certain range. There are very few serial killers who commit crimes from a distance."

Su Chen drew out the map of Chuzhou City on Baidu, and marked four action locations with a brush, and then established a simple coordinate axis on it:

"Beimei, which has the highest crime rate in the world, very few serial murderers commit crimes at a distance. Many commit crimes within a certain living radius."

"As long as we use the existing information to construct a three-dimensional city model based on the Manhattan measurement method, we can estimate the location of the murderer's next crime with a high probability!"

Manhattan Metrology?

Everyone was confused!

What is this?

Only Ding Zi's eyes lit up!

"Manhattan Metrology?"

"Last time I went to New York City to attend a lecture on global criminal investigation. A Chinese mathematician mentioned—"

"Manhattan measurement method, also known as Manhattan distance algorithm, taxi geometry, is a mathematical formula derived from probability. It establishes three-dimensional space modeling on the city map, and then inputs specific data. The more data, the extrapolated probability Higher..."

"In short, this is a very advanced criminal investigation technology!"

"I heard that some behavioral crime experts from the Ministry of National Defense and the FBI of China are researching this thing!"

After listening to Ding Zi's words, everyone fell into a trap.

this……

It completely involves their blind spots of knowledge!

What Manhattan metrology, what three-dimensional space modeling...

With a few mathematical formulas, the location of the murderer's next attack can be deduced. Isn't this too mysterious?

Maybe the murderer didn't even think about where to commit the crime himself!

at this time.

I saw Su Chen controlling the mouse with his right hand. With his left hand crackling on the keyboard, he constructed a city space model on the computer at an extremely fast speed, and j dazzled everyone.

If the boss of the construction group sees this fast drawing speed, he will definitely offer tens of millions of annual salary and hire Su Chen to go to work!

"Su Chen, who is he..."

"Even the legendary criminal investigation technology like 'Manhattan Distance Algorithm' can..."

Ding Zi sat on the side, staring at Su Chen sideways.

She suddenly found out. When a man works hard, he becomes more handsome!

The sword eyebrows are straight, the eyes are confident, the eyes are turning rapidly, and the face is rigorous and serious!

"Okay, so handsome..."

Ding Zi was moved quietly, but she didn't show it on the surface.

After a few hours.

"ok!"

Su Chen left the keyboard with his hands and let out a rough breath.

Presented in front of everyone is a 3D city model of half of Chuzhou City. Many buildings, streets and rivers are all clearly constructed.

Fearing that Ying Baisha and the others would not understand, Su Chen specially marked the crime area with a red line.

"These areas covered by the red line..."

Ying Baisha stepped forward, his eyes widened, "Could it be the place where the murderer will commit the crime next time?"

"To be precise, it is the location with the highest probability of committing the crime."

Su Chen sat on the sofa chair. Stretching, "After all, the data we have is limited, and it is impossible to accurately calculate a certain location. These two streets are already the limit of what I can do."

He pointed to the computer screen.

I saw that hundreds of red lines and punctuation marks crossed and covered the two streets of Beicheng District.

These two streets are the places where the murderer has the highest probability of committing crimes next time!

The further you go, the smaller the chances!

"Quick...quick!"

"Xiao Zi. Xiao Zhang, find out where these two streets are!"

Ying Baisha blushed and shouted excitedly.

Ding Zi quickly took out her phone. After checking for a few seconds, "Response! It's between Nantang Yujie and Beihu Road!"

"good!"

"Very good!"

Ying Baisha straightened his waist, his eyes were full of ecstasy. "At that time, we will send out all the police forces to act in plainclothes, in groups of two, and cover these two streets with a carpet! I won't even let a fly fly out!"

"What the hell, I don't believe it, I can't catch this bastard grandson!"

"call……"

Ruan Liqun, Ding Zi, Zhou Tonghao and others couldn't help but breathe a sigh of relief.

It seems that this case has been solved.

"Brother Su!"

"Thanks!"

"Thank you!!"

Ying Baisha turned around and held Su Chen's hand, addressing him. Also became a brother!

"Hehe, in response, you said thank you too early..."

There was a wry smile at the corner of Su Chen's mouth, "The Manhattan measurement method is just a probability algorithm, and it cannot be guaranteed to be 1% accurate. It can only be said. The hope is relatively high."

"It's better than waiting, isn't it?"

Ying Baisha laughed.

Su Chen also smiled, "That's right."

"Awesome!"

"so amazing!"

"Brother Su is much better than any criminal investigation expert!"

"Contemporary Bao Zheng!"

"I think Di Renjie is reincarnated!"

"This reasoning ability, Conan will have to obey!"

"Great God, are you accepting disciples?"

Several law enforcement officers and technicians immediately cast themselves on the ground in admiration.

Only Zhong Hua gritted his teeth and reprimanded:

'Hmph, what kind of idiot Manhattan measurement method, in the final analysis, is it not based on guesswork? "

'At that time, if you mobilize the crowd and fail to catch the murderer, I'll see how you end up! '

Su Chen got up and moved around.

After making a cup of tea, I focused my eyes on the small blackboard and continued to think.

actually.

His reasoning abilities were not fully utilized.

The Manhattan measurement method is just one of several heaven-defying techniques recorded in the skill book "Encyclopedia of Advanced Criminal Investigation Techniques".

According to Locard's exchange principle, as long as the criminal enters the crime scene, he will leave something more or less, either a trace or a substance, and it is impossible to leave nothing behind.

He only needs to go to the four crime locations and take a look, and with his pair of fiery eyes, he will definitely find some clues!

only……

It was a bit troublesome, and he was too lazy to go.

And, there is one more important thing tonight!

Action to pull out the devil!

Siege the Witch Congregation!

at this time--

A law enforcement officer hurried into the case discussion room:

"Responsive!"

"People from the Jinling War Zone have arrived!"
