Sun Dianjun, 27 years old, is a doctoral student jointly trained by the Chinese Academy of Sciences and relevant departments. His undergraduate major is mathematics. Later, because he likes to play games, he began to study computer algorithms and is quite accomplished in big data analysis.
The bad relationship between this young and extremely smart boss and data analysis originated from his passing by a girl who smelled like peach when he was strolling on the Peking Overpass when he was a graduate student.
Perhaps it was the hormonal smell of the girl that attracted the attention of this single mother-to-child academic master, but when Sun Dianjun turned his head, he found that the girl had disappeared into the vast sea of people. He ran back to the laboratory and looked at those who were typing codes.
The seniors and sisters shouted:
“I want to make a project!”
Sun Dianjun, who missed the opportunity, decided to use his lifelong learning to write a set of analysis algorithms covering the entire city of Peiping. Through the information obtained with his own eyes, he analyzed the most likely trajectory of the girl's actions.
There are tens of millions of people in Peiping, but he can only think of the clothes the girl is wearing and the peach-like fragrance on her body. This is an impossible thing, but Sun Dianjun is confident that he was born to create the impossible.
Three months later, Sun Dianjun, whose hairline had moved three centimeters, handed over his results with dark circles under his eyes. He succeeded. A clear trajectory appeared on the map of Peking City. He changed into a suit.
I chose a gentle evening, stood on the route I had calculated, and saw the same girl in the burning clouds.
This incident is also a good story in the relevant departments. This kind of romance between science and engineering men has attracted many specialists who are also engaged in research. This system has also been retained and used in the tasks of relevant departments.
Now facing Guderian who is old enough to be his grandfather, Sun Dianjun is not afraid at all. He is confident that his system, which was born with love, can easily analyze Xia Mi's trajectory and find the most likely Nibelung.
point.
"Hahaha, that's a good relationship." Guderian was not angry, and smiled kindly, but there was a hint of thorn in his words: "I also want to see if the young people who have the same speaking skills as me are better than their predecessors."
.”
Sun Dianjun raised his head and ignored him. A big hand suddenly pressed on his shoulder. Lei Guan walked behind him at some point. Only then did Guderian realize that the old man with white beard and hair looked like a
He was as tall as a little giant, more than two meters tall. His big hands like cattail leaf fans pressed on Sun Dianjun's back, preventing him from moving.
"It's a good thing for young people to be energetic, but Professor Guderian is a guest. Xiao Sun, you can't do this." Lei Guan patted Sun Dianjun on the shoulder, with such force that Sun Dianjun almost thought he had been patted to the ground.
He curled his lips, apologized to Guderian, shook his shoulders, and broke away from the shackles of Lei Guan.
"Ahem, let's get started, Professor Guderian, introduce to you my brainchild, the Peach System!"
After coughing a few words to relieve his embarrassment, Sun Dianjun pushed the blackboard to reveal the display screen behind it. The display screen that occupied the size of a wall was emitting white light. In the center of the screen was a simple drawing of water honey.
Tao, the painting technique is very rough, and it looks like a round butt to Guderian.
The next second, the peach slowly disappeared, and an extremely complex map appeared on the screen. It was Beiping, the capital of China, but the complexity of this map was far beyond comparison.
From the various bus routes and subway lines to the morning and evening rush hours of each road section, to the weather and building types in a certain area, from the terrain conditions to the small hutongs and dark alleys, a digital Peiping appeared on the screen.
"Xia Mi, born on October 30, 1993, graduated from Cardiff High School in 2010. According to records in the file, his parents are both deceased and he has a mentally retarded brother, but he is missing now.
Preliminary judgment is that that brother is another Dragon King."
Sun Dianjun picked up a pen from the side and wrote the word "brother" on the blackboard: "What we have to do is to find where this brother is."
"It is impossible for a person to suddenly appear in the world, even if he is the Dragon King. Before Xia Mi entered school, she had studied in public junior high schools and elementary schools in Peking for a period of time. At that time, she had not entered our school.
Vision, this part is what I want to complete.”
Before he finished speaking, a clear red trajectory appeared on the map. Sun Dianjun clapped his hands and said: "This is the trajectory of Xia Mi's actions in elementary school that I obtained through data and personality analysis and adding algorithms."
"This is her elementary school." Sun Dianjun pointed to a red dot, and then moved his finger: "This is her home, but according to her personality, it is impossible for her to go to and from school honestly at two o'clock and one line.
The footsteps of elementary school girls, so the overall trajectory is an oval with endpoints at school and home."
What is shown on the screen is an irregular curve, roughly in the shape of an oval, including several snack bars around the school, doll shops and other shops that girls like, as well as bathrooms, vegetable markets and other places.
"Brother Xia Mi's disappearance can be judged from the records. It probably happened when she was in elementary school. Considering that she looks like an elementary school girl, it is impossible for her to wander around in Peking. It would be too conspicuous. In other words, the Nibelungen
, hidden in this action trajectory.”
"Now we only need to add the trajectory of actions in junior high school and the trajectory of actions in high school, and see where these trajectories intersect, we can find the Nibelungen."
Sun Dianjun folded his arms, behind him, relying on China's huge computer system, the algorithm he was proud of was slowly running. The huge data constructed a realistic enough Xia Mi in the virtual Peiping, simulating countless possibilities.
trajectories, and then compare them one by one until you find the last one.
Guderian raised his head. The atmosphere here reminded him of the execution department run by his good friend Schneider, but he had to say that the other party's algorithm was indeed effective. On the screen, countless curves rose and fell, crawling across the entire map like snakes.
.
The map keeps zooming in, from the Second Ring Road to the Sixth Ring Road, and then to Tong County, including the entire Peking and surrounding suburbs.
"Then, we remove school and home from the most frequent locations, so the most likely location of Nibelungen is...in the subway, Nibelungen is in the subway!"
Sun Dianjun pointed to a section of the subway and said: "This section of Line 2 is the most common place, and the Nibelungen is most likely to be here."
Seeing Sun Dianjun come to the conclusion, Guderian shook his head: "You believe in computer technology so much that you don't even have basic judgments. You don't even think about how Xia Mi can come in and out frequently if he wants to live in the human world."
Nibelungen.”
As he spoke, he pointed to another location: "If you ask me, this is the most likely location."
Everyone in the conference room followed his finger and saw that it was a large bathhouse that was no longer common: "The Nibelungen has to cross a boundary, and this boundary, according to ancient data, is generally
