Deep Space Fleet

After the dinner, Zhang Yuan anxiously returned to his room and turned on his personal tablet. There is an idea left by my father on it - "A New Algorithm for Community Discovery".

The ideas left by Dad are very innovative.

After half an hour of pondering, Zhang Yuan was surprised to find that the algorithm found by this community can be very suitable for turbulent flow problems!

"Is it possible to use it?"

A scorching flame rose from the heart!

Community discovery is a very classic problem in graph theory, especially community discovery in complex networks, which is a major research focus in informatics.

The nodes in the network can be divided into groups, and the connections between the nodes in the group are relatively dense. These dense node groups are called a community structure.

According to Zhang Yuan's intuitive thinking, a turbulent flow can be regarded as a complete community structure.

The difficulty of analyzing and researching a single community will be greatly reduced.

"However, after a single community has been analyzed clearly, how can the data be combined?"

It is impossible to analyze the whole, and the value of the algorithm is not very great.

This problem is very confusing, and the difficulty of trying to solve it is unknown.

Zhang Yuan frowned tightly, for a while, he didn't have a good idea.

Now, there are two paths before Zhang Yuan. First, copy his father's inspiration and sort out this "community discovery algorithm in complex networks", and he can write a good article.

According to his current understanding, it is not a problem for this article to be published in a top-level journal, and it is more than enough to be used as a graduation thesis.

The second direction is to continue to solve the turbulence problem and integrate this "community discovery algorithm" into a small part of the paper.

But if the follow-up part is handled poorly, this good idea will be for naught.

"How should I choose?"

Zhang Yuan pondered for a moment, his face was uncertain, and finally heaved a long sigh.

He found that deep in his heart, he still wanted to choose the second path, and he really didn't have the taste to copy his father's ideas again—even though those were all articles his father willingly gave him.

money?

reputation?

He doesn't need these now.

Zhang Yuan reopened the photos of his father, and the memories of the past seemed to be coated with a layer of golden light after the baptism of time.

Zhang Yuan said in a low voice: "Father, thank you."

...

Time is like running water, passing day and night.

As the communication delay increases, the communication with the earth becomes more and more difficult, and the atmosphere in the spacecraft is gradually becoming oppressive. There are also significantly fewer people chatting on the roadside and exercising in the gym.

Everyone goes to work after eating, and goes to bed after work, as if only by being busy can we forget those troubles.

Whether you like it or not, people have to adapt to this universe.

Zhang Yuan's hot spot finally passed, and the Fowles wealth list was changed to Federal currency denomination again. A few more newcomers emerged from the list, but there was not much splash.

Everyone is only interested in the first Mr. 100 million yuan, and not much interested in the second and third ones.

The money on the earth is not the money that can be used on the spacecraft. It's just a number, and it doesn't make much sense if you look at it too much.

On the contrary, the competition in the academic list is very fierce, and the first place has changed several times in a row.

The truth in the universe, in this small society, starts to become more eye-catching.

"Extraordinary! The ranking of Star University has officially entered the 500th place in all mankind!"

"Our Deep Space University has already been killed in seconds. The 1,000th place of all human beings can't get in!" Ye Kaifu, the news PHS, was the first sentence when they met.

He said with a sad face: "Mr. Zhang, as a master graduate student of Deep Space University, you have to do something. My teacher is urging me to publish papers all day long. It's really annoying."

Zhang Yuan was startled, "Shen Space University's failure to rank can't be blamed on me... Where are those professors?"

"Professors are busy debugging the spaceship, where is the time to write papers? Such a big spaceship!"

"Wait a minute, Xingchen University has good results again? They took medicine and failed, so awesome?"

"I'll forward it to you."

There was a guy named Zhang Yingbo who wrote an innovative paper on "light stagnation technology" that caused a little buzz.

Light stagnation is currently a hot topic in research, and its principle is to interweave light waves together so that they stop on their own tracks. The trick relies on tweaking light waves so that they meet at so-called "exceptional points."

With this principle, people can use lasers to send and store information.

Zhang Yuan read it with relish for a long time, and was amazed at the innovation of this paper. He was a little puzzled, how this Zhang Yingbo could write such a paper under such poor experimental conditions.

And a few days ago, a boy named Xiao Weixing wrote a paper on "photocatalyst", because there were too many professional terms involved, and Zhang Yuan couldn't understand it because he didn't understand the major, so he just There is no way to evaluate.

Anyway, the industry responded well.

By the way, this guy is also from Star University.

There is also a paper on "Gene Matching", written by a female student named Gina, which explores the mutual selection between genes from the perspective of big data, and the mathematical model is quite good.

This guy is from Star University!

In his 20s, he was the age with the most whimsical ideas. The fierce competition also caused Zhang Yuan's ranking to gradually drop, all the way down to more than 100.

"Zhang Xueba, aren't you doing turbulence? A turbulence can kill them all!" Ye Kaifu said maliciously.

Zhang Yuan had a bitter face, "Go, go, do you think this problem is so easy to do?"

"Aren't you the number one in professional grades? I'm just a weak chicken. In the past eight months, there is only one paper... ranking 233."

Zhang Yuan suddenly realized that this Ye Kaifu was here to sow hatred. He has not published a paper for such a long time, and he is about to be caught up by Ye Kaifu.

Zhang Yuan couldn't help feeling a little annoyed, but he had to stick to the topic he chose no matter what, "Are you so sure that I can't do it? Let me tell you, come here..."

"I have grasped the true essence of the turbulent flow problem, and created an equation called the leaf-equation, specifically, its vector form is =-?p+ρF+μΔv..."

"What?! True or false?"

Swallowing and spitting, Ye Kaifu felt his heart stopped beating. Although he didn't understand much, he was deeply aware of the importance of turbulence problems. Moreover, as long as you don't understand, it doesn't matter if the other party talks nonsense!

"Wait, why is it called a leaf-equation?"

"Ye Kaifu Equation, because of your encouragement just now, it gave me the motivation to move forward and gave me the determination to continue. So if I really achieve results, I will call it the Ye Kaifu Equation."

Ye Kaifu suddenly realized, he immediately smiled and said: "That's fine! In order to show my gratitude, all the machines I repair in the future, including the mobile phones repaired by various girls, will secretly engrave your name Zhang Yuan ,How about it?"

"you dare!"
