Chapter 423 Mobile Phone Recording
Airport, terminal building.
In the spacious and bright VIP room, a handsome young man is sitting on the sofa with his laptop open.
The city with 4,000 intersections is running at a lag, and all the traffic and people are rushing around. Sometimes time is suspended, and sometimes it flashes and teleports. It seems to be a headache.
Song He didn't touch the keyboard, just thinking.
When cities reach this scale, the new entry point for mathematical models is likely to be chaotic systems!
He is very familiar with chaotic systems. When he first learned about nonlinear systems, he went through exercises on chaotic systems in two major books, such as one-dimensional chaotic systems, the probability density function of Logistic-Map mapping, and the encryption factor sequence of two-dimensional chaos. Chaos attractor and so on, they are all old acquaintances!
Generally speaking, chaotic systems are very sensitive to initial conditions, exhibiting a quasi-random state that is neither periodic nor convergent.
An important concept in chaotic system theory is bifurcation!
A change in one parameter causes a sudden reaction in the entire system. Quantitative changes lead to qualitative changes. This is the so-called bifurcation!
For example, on the road on the computer at the moment, if the number of vehicles on a road reaches a certain level, an accident will occur. The vehicles in the accident block the middle of the street, and the entire road is completely paralyzed, which can be regarded as a bifurcation!
With every fork, the complexity of the entire system doubles!
After multiple consecutive bifurcations, a vicious cycle occurs. The entire system crosses a certain boundary, changes from regular to irregular, and then enters a state of chaos!
Song He swept his eyes across the computer screen.
The city on the screen is stuck like a PPT, but it doesn't matter. Just look at the data in the lower right corner and you can clearly tell that the city has turned into chaos at this moment!
[Comprehensive congestion rate: 40%! 】
[Comprehensive congestion rate: 58%! 】
[Comprehensive congestion rate: 31%! 】
[Comprehensive congestion rate: 37%! 】
The values keep changing!
First, traffic accidents occurred at congested intersections, and certain streets were paralyzed one after another.
Traffic on the paralyzed streets was finally cleared, and accidents began to occur frequently on some streets with sparse traffic.
As a result, the congestion rate data jumped repeatedly!
The traffic situation in the entire city is very strange, as if something dirty is wandering on the streets, randomly triggering car crashes and killing people!
Song He tightened his lips and continued to think.
If the traffic flow of each street is abstracted as an initial point, the evolution process of the initial point will show a trajectory, that is, a flow. When all flows are combined, a phase diagram will be formed, representing the entire city!
The geometric structure of the entire space manifold depends on the operator, and the operator depends on the parameters. The parameters continuously change with the number of traffic on the road. When a certain critical value is crossed, the originally smooth places in the phase space will be distorted!
This distortion, the jump in the system's mode, can be done using topology!
Topology!
Song He beamed, and for a moment, he had the pleasure of walking dozens of steps and suddenly enlightened!
He is a true topology expert! Those who have reached the topological boundary!
A large amount of inspiration suddenly burst out, but he had to pause for a moment and close the computer.
After thinking about it for a long time, my brain was overheated and I needed to cool it down to avoid smelling the aroma of roasted brains.
Secondly, it’s time to board the plane!
Song He hurriedly left the VIP room with his computer bag on his back, passed the ticket gate and went to the corridor bridge, all the way to the first class cabin.
There were only two first-class seats on this plane. As soon as he entered, there was already someone in the seat next to him.
A middle-aged woman with heavy make-up, a plump figure, permed hair, and jewels on her body.
To be precise, the jewelry is so dazzling that it is a bit dazzling. There are several gold and jade bracelets on the wrists, and the fingers are covered with gemstone rings. There are also two necklaces hanging on it. The dazzling style reminds people of the evil dragon in Western legends who likes to hoard treasures.
Song He sat down silently, not interested in talking at all, so he might as well continue studying mathematics.
The computer is turned on, the fan is spinning, and the laggy big city continues to run.
In a city with 4,000 intersections, maintaining traffic stability is extremely important.
When a disturbance t is applied to the system, the system's response is Δt. If Δt approaches zero as time goes by, the stability is passed.
In a city, after a street accident occurs, the road can be quickly restored without causing a traffic jam in the city!
Song He swallowed a few capsules to speed up his mental calculations.
First linearize the entire system. When it is not at the singular point, the local topology of the system phase space remains unchanged, and the columnar Jacobian matrix...
The transformed basis vectors are not orthogonal. Calculate the area for the basis vectors at different positions and obtain the area microelement expression...
After calculating and calculating, Song He's brain cells burned like coals and ventilation, and massive amounts of data rolled by!
Unconsciously, the plane entered level flight.
Next door, the bejeweled woman suddenly took out her mobile phone and answered the call.
At first Song He didn't pay attention to her nagging, but a few words escaped his ears. It seemed that this person was a female boss.
After about ten minutes, a keyword suddenly jumped into my ears. Song He's ears suddenly stood up!
"There are only two hot spots recently, one is Song He Su and the other is Sleeping Tablets. I tell you, I have to pay no matter how much it costs to get them!"
"Don't you know the market? Song He always pays twice as much for reselling domestically, and twenty times as much for reselling overseas! Liu Laizi from Basong Town, his four ships carry four batches of goods to Ryukyu and Canberra a week. A small boat is worth two million, and we will rob them all when we get ashore!”
"Liu Laizi is so arrogant now that he has disappeared! People from all walks of life went to beg him, but he was nowhere to be seen! What a damn villain! I was the one who built the bridge for him when he was pouring veterinary medicine!" The female boss spat.
"Lao Xing and Fatty Pu were already on the line. They took two carloads of short-sleep tablets and went to Maozi to test the water. They hid the test results and didn't tell them. If they didn't tell them, wouldn't they just be making money? Isn't it just that they would burn themselves after crossing the river? Bridge? If we lose the money, they will be miserable because of the poor news in the morning!"
"The production of short-sleep tablets will be expanded, but the factory has not been built yet, and it is not enough. You don't know how popular this product is. The online price is more than ten times higher and you can't get it. The goods are all in pieces, and there is not enough to feed the birds! "
"The goods are released at eight o'clock every night. More than 300 people under me grab it with their families. It's impossible to grab it by hand! It's gone in less than half a second! Lao Xing and the others use electronic grabbing, which is done in Southeast Asia. I saw the equipment that came over once last year. There were several rows of eight-meter-long shelves in the basement, all filled with mobile phones. Thousands of mobile phones were automatically swiped! Second-hand mobile phones are very cheap. Each one costs about a hundred yuan, and the electricity bill is even higher. never mind!"
"Anyway, I'm trying to find a way. If that doesn't work, I'll stop the workers on the road and stuff them with money. There's always a way to stuff two bags of money into them. I've heard rumors that someone is already planning to go to Bangalore to build a factory and build a batch of the same appearance. The starch tablets came out to test the water. The difficulty was the anti-counterfeiting packaging. They asked Chenghuang to order the anti-counterfeiting packaging factory..."
"Chenghuang Butler, Wei Liqun! Don't forget that that person is not a good person. I think those factories in Banga will definitely catch fire. Do you want to bet?"
When Song He heard the first two sentences, he silently turned on the recording on his phone and placed it on the small table.
The phone was in charge of recording, and he continued to stare at the computer screen, immersed in mathematics.
After several hours of long flight, finally, a special system prompt popped up in front of me!
