I kidnapped an alien civilization

"Boss, why did you discourage their enthusiasm, especially that little girl, it's so pitiful, did she do something wrong?" Sitting in the car, Xia Qing asked.

People come and go outside the car window, and everyone is running around for their lives. 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 today's decision in a few years' time."

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

Now Li Mo suddenly finds that exploding liver seems to be a common thing for him.

On the first day back to Yanda, he started "retreat".

Although his dedicated assistant Xia Qing always criticized him as a joke about his life, in fact, even if Li Mo didn't do it deliberately, his desire to solve the problem was urging him to do it.

The task entrusted by 912 is imminent. It is self-evident what an excellent rocket engine means. Li Mo feels that there is a lot of pressure on his shoulders at this time.

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

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 turbulent flow 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 big problem: it is a nonlinear partial differential equation, which is very difficult to solve, and 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 complicated mathematical equation on the draft. This is the equation he summed up 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 pod.

The difficulty of these equations is that there are too many unknown conditions, and it is also very difficult to propose initial conditions. From the point of view of stochastic mathematics, turbulent flow is a typical initial condition sensitive dependence problem. If there are small deviations from the initial conditions, significant differences can appear in the solutions of the equations.

"Maybe we can use direct numerical simulation to solve this problem." He felt a burst of inspiration in his mind, because in general, fluids are considered as continuous media, that is, any small fluid particle contains a large enough number of molecules, so that molecules The fluctuations of the fluid have little effect on the motion of the fluid particle itself, so the most accurate numerical methods can be used to solve these complex equations.

With a goal, Li Mo was full of energy. He turned on the computer, and what he needed now was to make a computer program that could run the full numerical simulation of DNS.

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

The cursor on the screen flickered: "Master, I am here!"

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

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

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

He typed on the computer: "Approval authorization, this authorization is limited to access to computer programming knowledge."

Xiaohua: "Authorization has been approved, and computer programming knowledge is being acquired"

The network light of the alien's notebook kept flickering, and Li Mo took advantage of this spare time to lie on the chair and close his eyes.

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

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

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

Now it is only necessary to input these experimental data into the computer. Li Mo frowned as he looked at the densely packed manuscripts in his hand.

It is a huge project to input these data and their mathematical logic into the computer.

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

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

4500 hours? Isn't that more than 200 days? Li Mo now realizes that he has neglected the complexity of turbulent flow. Compared with some super projects, these data may not be much, but there are innumerable structural relationships between them, and the computing power of a laptop computer CPU cannot competent.

No, it's too long, the rocket engine design can't wait for such a long time.

"Xiao Hua, can you shorten the time?" Li Mo typed.

Xiaohua: "Maybe I can use some other means, but I need to be authorized by the owner to access the external network."

At this time, Li Mo remembered that Xiaohua used to capture the cases of foreign hospitals through the Internet during the process of developing the J antibody.

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

Could it be that Xiao Hua really planned it this way? Doesn't she know that most of those foreign supercomputers use physical defense methods?

The supercomputer centers in foreign countries all adopt the hard backup method, which loads the required calculation programs into the supercomputers through the hard disk loading method, and these computers are not connected to the network.

No matter how clever a hacker is, he is powerless in front of physical defenses, so the world has never heard of that supercomputer being hacked.

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

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

Regardless of technology or opportunity, it is a good way to solve problems, and artificial intelligence will not lie to its master.

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

Xiao Hua: "The authorization has been approved, and the data is being collated."

Looking at the cursor on the computer, Li Mo knew that this would not be something that could be done in a short while. Remembering the requirement of the system task on graduating early, he decided to read the biology book needed for undergraduates again.
