Deep Space Fleet

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

The ideas left by Datong are very innovative.

半 After half an hour of thinking, Zhang Yuan was surprised to find that the community discovery algorithm can be very suitable for turbulence problems!

"Can it be used?"

A hot flame rises from my 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.

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

According to Zhang Yuan's intuitive idea, a turbulence can be regarded as a complete community structure.

进行 Analysis and research on a single community will reduce the difficulty a lot.

"How can you merge the data after the analysis of a single community is clear?"

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

问题 This problem is very confusing, and the difficulty is unknown.

Zhang Yuan's brow frowned tightly. For a while, he didn't have a good idea.

Now, two paths are facing Zhang Yuan. First, copying his father's inspiration and sorting out this "community discovery algorithm in complex networks", I can write a good article.

According to his current understanding, this article is published in top-ranking first-region journals and is not a problem. It is more than enough to use as a graduation thesis.

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

But if the subsequent parts are handled badly, this good idea will be blind.

"How should I choose?"

Zhang Yuan thought for a moment, his face was cloudy, and he finally sighed.

发现 He found that deep in his heart, he still wanted to choose the second path, so he had no product to copy his father's ideas again-although those were articles that his father was willing to send to himself.

Money?

Reputation?

He doesn't need these now.

Zhang Yuan reopened his father's picture, and the memories of the past passed through the baptism of time, as if plated with a layer of golden light.

Zhang Yuan said lowly, "Father, thank you."

Uh ...

Time is like a flowing water, passing day and night.

As the communication delay increases, the communication with the earth becomes increasingly unsmooth, and the atmosphere inside the spacecraft is slowly becoming depressed. The number of people who exercise at the gym and chat in the gym has also decreased significantly.

Everyone works after eating, and then goes to bed after work. It seems that only when you are busy can you forget those worries.

Whether it is willing or not, people have to adapt to this universe.

Zhang Yuan's hot spot has finally passed, and the Falls wealth list has also been changed to federal currency denomination. Several newcomers have emerged from the list, but there have been no big splashes.

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

Money on earth is not money that can be used on a spaceship. It's just a number. It doesn't feel too much if you look at it too much.

However, the competition on 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, began to become more eye-catching.

"The nickname! The ranking of Star University has officially entered the 500th place among all human beings!"

"Our deep space university has been spiked. The 1000th human being can't get in!" Ye Kaifu's news was a little clever, and the first sentence to meet was this.

He said frowningly, "Master Zhang, as a graduate student at Deep Space University, you have to do something. My teacher urged me to publish papers all day long. It was really annoying."

Zhang Yuan was startled. "Deep Space University can't get up, can't blame me ... what about those professors?"

"Professors are busy debugging the spaceship. Where can I write a dissertation? Such a large spaceship!"

"Wait a minute, Xingchen University has a good result again? They can't cure it, so great?"

"I'll forward it to you."

There is a guy named Zhang Yingbo who wrote an innovative paper on "light condensation technology", which caused a small sensation.

Light stagnation is a current research hotspot, and its principle is to interweave light waves together to stop them in their natural orbits. This technique relies on adjusting the light waves so that they meet at what are called "exception points".

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

Zhang Yuan watched with interest for a long time and was amazed by the innovation of this thesis. He was a bit puzzled how Zhang Yingbo wrote such a paper when the experimental conditions were so poor.

A few days ago, a boy named Xiao Weixing wrote a "photocatalyst" dissertation, because there are too many professional terms involved. When adding a specialty, Zhang Yuan didn't understand it. No way to evaluate.

Anyway, the industry has responded well.

Hey, this guy is also from Star University.

There is also a paper on "gene matching", which was written by a female student named Gina, who explored the mutual selection between genes and genes from the perspective of big data. The mathematical model did a good job.

This guy is from Star University!

多 20s is the age with the most imagination ~ www.readwn.com ~ The fierce competition has also led to the ranking of Zhang Yuan gradually, all the way down to more than 100.

"Zhang Daba, aren't you doing turbulence? One turbulence can kill them all!" Ye Kaifu said unwillingly.

Zhang Yuan faced bitterly. "Go and go, do you think this problem is so good?"

"Don't you have the highest professional grade? I'm just a weak chicken. In these eight months, there is only one thesis ... ranked 233."

Zhang Yuan was surprised that Ye Kaifu was here to pull hatred. He hadn't published a dissertation for so long, and was almost caught up by Ye Kaifu.

Zhang Yuan couldn't help but be a little angry, but the subject of his choice must be persisted no matter what, "You are so sure I can't do it? I tell you, you come over ..."

"I grasped the true nature of the turbulence problem, and created an equation called a leaf-equation, specifically like this, and its vector form is =-? P + ρF + μΔv ..."

"What ?! Really?"

Choking throat and spit, Ye Kaifu felt his heart stopped beating. Although he did not understand well, he knew the importance of turbulence. And, as long as you do n’t understand, it ’s okay even if the other party is nonsense!

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

"Ye Kaifu's equation, because your spurring just gave me the impetus to move forward, so that I have the determination to continue. So if I really achieve results, I call it the Ye Kaifu's equation."

Ye Kaifu suddenly realized that he immediately laughed and said, "Let's do it! In order to show my gratitude, all the machines I repaired in the future, including the phones repaired by various girls, secretly engrave your Zhang Yuan name ,how about it?"

"you dare!"
