"Boss, why do you want to dampen their enthusiasm, especially that little girl? She's so pitiful. Did she do something wrong?" Xia Qing asked while sitting in the car.

People are coming and going outside the car window, and everyone is running for life. The ideal is beautiful, but the reality is cruel. Li Mo said: "She is not wrong. What is wrong is that she chose the wrong direction. Maybe she will be grateful for what she has today in a few years."

Decide."

Xia Qing was thoughtful, this young boss could always say some thought-provoking words.

Now Li Mo suddenly found that liver failure seemed to be a common thing for him.

On the first day he returned to Yanda, he began to "retreat".

Although his dedicated assistant Xia Qing always criticizes him for making fun of his life in this explosive way, in fact, even though Li Mo did not do it deliberately, his desire to solve the problem prompted him to do it.

The mission entrusted by 912 was imminent. It was self-evident what an excellent rocket engine meant. Li Mo felt that there was full pressure on his shoulders at this time.

This feeling often reminded him of the mood when he first tried to solve the Coraz conjecture. At that time, he always felt that there was a big stone in his heart. If he couldn't solve it, he wouldn't even have the motivation to go to the playground to play ball.

In essence, this desire to explore the unknown seems to be the same?

Now turbulence is the unknown he needs to explore.

The Navier-Stokes equation describing turbulence phenomena was born in the 19th century. It is based on the classical Newtonian system and can theoretically measure the motion of any fluid when the initial conditions are known. However, there has always been a

The big problem: it is a nonlinear partial differential equation that is very difficult to solve. There is no mathematical tool that can solve these equations.

"It's difficult to solve, can't be solved by manpower?" Li Mo stared at the complex mathematical equations on the draft. This was an equation he summarized based on the data provided by the 912 rocket geek. It is an extended version of the Navier-Stokes equation, which can be described more accurately.

What exactly happened in the rocket ignition chamber?

The difficulty of these equations is that there are too many unknown conditions, and it is also difficult to propose initial conditions. From the perspective of stochastic mathematics, turbulence is a typical problem of sensitive dependence on initial conditions. If there is a slight deviation in the initial conditions, then the equation

There may be significant differences in the solutions.

"Perhaps we can use direct numerical simulation to solve this problem." He felt inspired, because fluids are generally considered to be continuous media, that is, any small fluid particle contains a large enough number of molecules, so that the molecules

The fluctuations of have little effect on the motion of the fluid particles themselves, so the most accurate possible numerical methods can be used to solve these complex equations.

With the goal in mind, Li Mo was full of energy. He turned on the computer. What he needed now was to create a computer program that could run a full numerical simulation of DNS.

"Xiaohua, are you there?" He once again awakened the artificial intelligence program. If there is anyone who is most qualified for the task of making a program, it is the intelligent program written by the alien program.

The cursor flashed on the screen: "Master, I'm here!"

"Can you make complex computer programs?" Li Mo typed on the computer.

Xiaohua: "Of course, but in order to better match the program and needs, the owner needs to authorize Xiaohua to access the human Internet."

Li Mo hesitated for a moment. This was not the first time that artificial intelligence had proposed such a condition, but he thought that Xiaohua's memory would be "deleted" after completing the task.

He entered on the computer: "Approve authorization. This authorization is limited to accessing computer programming knowledge."

Xiaohua: "Authorization approved, computer programming knowledge is being acquired..."

The network light of the alien laptop kept flashing. Li Mo took advantage of this free time, lay down on the chair and closed his eyes.

The knowledge acquisition was completed much faster than he expected. Two hours later, he was awakened by the sound coming from the computer speaker.

Xiaohua: "Master, the computer programming knowledge has been acquired and is being optimized..."

"Optimization completed... Please enter the data you need to analyze, and Xiaohua will create an application based on the data."

Now all we need to do is input these experimental data into the computer. Li Mo looked at the dense manuscripts at hand and frowned. There was no way. Turbulence was not so much a mathematical problem as it was actually a numerical problem.

Completely inputting these data and their mathematical logical relationships into the computer is a vast project in itself.

24 hours....

48 hours....

72 hours....

sunrise....

Sunset.....

After typing in the last number, Li Mo was about to stretch himself comfortably when a line of words appeared on the computer that attracted his attention.

Xiaohua: "Master, based on the optimized computing power of the laptop CPU, it will take 4500 hours to analyze these data."

4,500 hours? Isn’t that more than 200 days? Only now did Li Mo realize that he had ignored the complexity of turbulence. Compared with some super projects, these data may not be much, but there are inextricably linked structures between them.

Relationship, the computing power of laptop CPU is simply not up to the task.

No, it's too long. The design of the rocket engine cannot wait for such a long time.

"Xiaohua, can you shorten the time?" Li Mo entered.

Xiaohua: "Maybe I can use some other methods, but I need the owner to authorize me to access the external network."

Li Mo then remembered that during the process of developing j-antibody, Xiaohua once captured cases from foreign hospitals through the Internet.

The only way to obtain computing power through the Internet is to control some foreign supercomputers and treat them like chickens to calculate their own programs.

Is this really what Xiaohua planned? Doesn’t she know that most of those foreign supercomputers adopt physical defense methods?

Foreign supercomputer centers all use hard backup methods, and the required calculation programs are loaded into the supercomputers through the hard disk. These computers are not connected to the network.

Even the most sophisticated hackers are helpless in the face of physical defenses, so the world has never heard of that supercomputer being hacked.

Thinking of this, he typed on the keyboard: "Xiaohua, do you have the technology to break through physical defenses?"

The cursor flashes and the little flower flashes: "It's not technology, it's opportunity."

Regardless of technology or opportunity, a good solution is a solution to a problem, and artificial intelligence will not lie to its master.

Li Mo entered: "Authorize Xiaohua to access foreign networks, and the time limit procedure is completed."

Xiaohua: "The authorization has been approved and the data is being sorted..."
Chapter completed!
