Technology: The naughty kid ruined my college entrance examination, but I turned over to nuclear fusion

Chapter 547

If it is

for an ordinary scientific researcher, knowing that things are wide enough and the scope is large enough, in fact, it is not particularly important.

Only by studying deeply enough in a certain field can it be possible to make some outstanding contributions to the country in a certain field, and let your scientific research results come in handy!

The point is on depth.

But for Lu language, it is naturally different!

If he is willing, he can quickly get started in any subject with the help of the system.

So… If the breadth is enough, it may also bring unexpected effects, such as combining the advantages of various disciplines and fields with each other to get some unexpected results!

“Under normal circumstances, if the intelligent group algorithm is used in the microsatellite network system, it can indeed improve part of the calculation ability.”

“In theory, it will not cause much conflict with MEMS systems.”

“But specific… It depends on the actual effect.

Lu Yu thought secretly in his heart.

He took a sip of tea gently, then closed his eyes and waited for Director Ye to restart this conference on the application of intelligent swarm algorithms in the aerospace field!

Soon…..

One by one, the team members are back together.

After they arrived, many people subconsciously glanced at Lu Yu with a puzzled look in their eyes.

“Didn’t Director Ye say before that for the time being, he and the Lu General Engineer should split up in two ways and deal with different research projects with each other?”

Although they had doubts in their hearts, they did not raise them directly, but waited for the answers to be revealed.

Director Ye also wasted no more time and officially announced the start of the meeting!

“Ahem.”

He cleared his throat and said solemnly,

“Let me talk to you about the key points first.”

“First of all, our path remains the same, the task is still to install the intelligent group algorithm on the microsatellite network, and try to solve the collision and interference problems it may encounter after continuous debugging!”

“As for why Chief Engineer Lu also came to the meeting… I just told him to come over and make a scene, so you don’t have to pay attention to it.

“Chief Engineer Lu, you won’t be dissatisfied if I say that, right?”

Director Ye asked jokingly.

“Of course not.”

A light smile appeared at the corner of Lu Yu’s mouth, and he shook his head and said,

“Aren’t I here just to make fun?”

“You tell yours, I listen to me.”

“Okay, then let’s continue to return to the whole, there are still many key points to be solved in the field of intelligent swarm algorithms in microsatellite networks.”

“Although during this time, our country has made a lot of development in the field of intelligent group algorithms, but in many practical application fields are still poor, especially in the field of microsatellite networks, we are likely to be the first time!”

Director Lin looked around and said solemnly,

“Do you know what the problems we are facing now are?”

“It’s a matter of group size!”

A researcher stood up and said.

“That’s right, so first, let’s talk about group size. Group size refers to the number of individuals included in the group, that is, the number of satellites. ”

The microsatellite network may have many, many satellites, maybe hundreds or thousands, and if we go according to our plan, we need at least 3,650 microsatellites, which is a large group size.”

“Why does swarm size have an impact on swarm intelligence algorithms?”

“Because when the group size gets bigger, it means that the problem to solve becomes more complex, just like when you have to take an exam, the more questions and the more difficult the questions, the more time and effort you need to spend on it.”

Similarly, when there are more satellites, more computing and communication are needed to find the optimal solution, such as how to distribute tasks, how to choose routes, how to avoid collisions, and so on. This will increase computational complexity and communication overhead, which means that it will consume more resources and time…”

Director Ye swept his gaze down!

Many people subconsciously lowered their heads and did not dare to be the first to stand up and answer.

They can’t be blamed for that.

After all….. When it comes to specific solutions, it’s not easy to think of a qualified method in a short time!

If there is a question with the answer you said, and others answer it easily, isn’t it extremely embarrassing?

So, the atmosphere of the meeting suddenly became a little strange.

It’s quite like when they are in school, students are worried that the teacher’s question will point to them, that is afraid that the teacher’s gaze will fall on their head!

“Ahem, doesn’t anyone want to stand up and express their opinion?”

Director Lin asked again.

This time, a researcher finally stood up cautiously and spoke his opinion:

“Director Lin, I think I face this problem. One possible approach is to design some efficient algorithms and protocols. ”

Oh? Expand on it and talk about it in detail.

Director Lin said with a slow smile.

“Enabling rapid exchange of information and collaboration between satellites can reduce computing time and communication, and also improve convergence speed and settlement quality to some extent.”

“I use an analogy, for example, to use some heuristics to simplify the problem or narrow the search space, or to use some hierarchical clustering to divide subgroups or subtasks, and then use adaptive or learning methods to adjust parameters or strategies…”

He repeated his thoughts in detail, and Director Lin’s face also showed a look of appreciation.

“Yes, it seems that you still have your own ideas.”

“I don’t need to tell you directly about every question, but he is the only one who responds to me, which is somewhat unsatisfactory to me.”

Director Lin shook his head and continued: “I have actually considered your method, and if you use this method, you have to consider the possible impact of group dynamics.

“Group dynamics, that is, changes in the state or behavior of individuals in a group over time and environment, that is, changes in satellites.”

“Microsatellite networks can change frequently, such as sometimes satellites joining or leaving the network, some satellites failing or returning to normal, and some satellites changing position or speed, and so on. These are the group dynamics that can have an impact.

“As for why swarm dynamics have an impact on swarm intelligence algorithms?”

“That’s because when the group dynamics get bigger, it means more uncertainty and instability to deal with!”

“When you go out, the more the weather changes and the less predictable, the more you need to prepare more clothes and tools. Of course, I could give many examples, but I’m sure you can see what I mean with this one. ”

As satellites change, they need to be more adaptable and robust to deal with situations such as how to deal with new satellites that join or exit, how to repair or bypass faulty satellites, and how to track or adjust satellites that change position or speed!”

“This increases system complexity and risk.”

“It will even reduce the reliability and stability of the entire system to a certain extent, so we must find a way to solve this problem.”

“Originally, I wanted us to discuss it, but in order to save time, I will first say what I think, can you see if it is feasible?”

“My vision is to design more flexible algorithms and mechanisms, so that satellites can dynamically adjust and adaptively learn from each other to cope with uncertainty and instability!”

“For example, you can use some feedback or update methods to obtain or pass information in a timely manner, and some redundancy or backup methods to increase fault tolerance or recovery.”

“On the basis of this, use some predictive planning methods to prepare or take emergency measures in advance!”

“What do you think?”

Director Lin asked.

Since this meeting is a discussion meeting, not a speech, of course, everyone should be involved, rather than Director Lin alone chattering in the first place, while everyone else sits down and listens like wooden people.

If that’s the case, it’s definitely a waste of the entire country’s scientific research resources!

After all, although the researchers present may not be comparable to Director Lin’s level in terms of scientific research strength and specific application ability.

But in the industry, it can also be called the first echelon – the existence of the second echelon!

If you just let them listen without thinking, then just a few graduate students or PhDs can cope with the task.

Lu Yu listened carefully on the side.

Although intelligent group algorithms are not his area of expertise, after listening to what Director Lin said, he felt that he had some unspeakable gains.

After thinking about it for a while, a scholar frowned and asked

, “Director Lin, I just thought about your thoughts.”

“I think while it’s possible to some extent, the capabilities of each satellite are hugely different.”

“If you go according to your ideas, will you…. Not detailed enough?

He pondered for a moment and raised a question.

“The question of difference is indeed a tricky one.”

“Or instead of using the term difference, I prefer to use the more accurate term of group diversity to express the difficulties we face!”

Director Lin lightly applauded, and then said,

“What is group diversity?”

“It is the difference in the type or function of the individuals in the group, that is, the difference in satellites! It is indeed a better description of the dilemma we face than the difference!

“As everyone must know, microsatellite networks may contain satellites of different types or functions, for example, some satellites are dedicated to communication and others are dedicated to remote sensing.”

“Different kinds of satellites have different functions and have great differences in practical applications, so the intelligent group algorithm must take all this into account, otherwise I am afraid that it will have a great impact on the algorithm itself!”

A middle-aged researcher subconsciously raised his hand and asked

, “I don’t understand Director Lin, what level is its specific impact?”

“It’s simple.”

Director Lin glanced at him and replied with a smile:

“When the diversity of the group increases, it means that there are more goals or constraints to consider, and when buying things, the more goods and the more different the goods, the more conditions you need to consider.”

“The more different the satellite functions, the more goals or constraints are needed to meet the needs and preferences of different satellites or missions!”

“Specifically implemented in our project, that is, how to balance communication quality and energy consumption, optimize navigation accuracy and coverage, improve remote sensing efficiency and quality…”

“The complexity and difficulty of the problem is to improve here, once these troubles cannot be solved, it will reduce the efficiency and effectiveness of the system.”

He paused and continued

, “But according to the saying of our Dragon Kingdom, there must be a road before the car reaches the mountain.”

“We can pre-calculate the strategy of diversified algorithms, so that satellites can be evaluated and selected in multiple dimensions!”

“Although it cannot fundamentally solve the problem, it can also meet the optimization problem of multiple objectives or constraints.”

“Let me end with an example, we can use some weighting preferences to express the importance of different satellites or missions.

“Do you mean to synthesize or separate different goals or constraints by some aggregation or decomposition method, and then exchange or negotiate to resolve conflicts or coordination between different goals or constraints?”

Listening to everyone’s discussion, a bold idea suddenly arose in Lu Yu’s mind!

Since the intelligent group diversification algorithm can achieve such a point, it is necessary to deal with the space threat of the Eagle Country…. Wouldn’t it be?

In his eyes, a sharp light suddenly flashed!

—-

was also when the research work was in full swing, Lu’s father and Lu’s mother who walked out of the community also saw two unexpected figures.

“Lao Lu?”

“How did you get here?”

Aunt Wang’s husband looked at Lu’s father and Lu’s mother who came out of the community with a puzzled expression, and his eyes were full of surprise.

Aunt Wang next to her also had a skeptical look:

“Are you guys going in for a stroll?” Or…”

Wang Shouren next to them, his expression froze even more: “This can also be met?” ”

This family of three never thought that in this area of Kyoto City, they would be able to meet Father Lu and Mother Lu again! Obviously, they met Lu Yu by chance a few days ago in Kyoto, and today they can meet his parents here?

Although it is said that traveling with the Lu family is the idea of Aunt Wang’s family.

But to be able to do so coincidentally, it is really… What a coincidence!

“We just went shopping around the neighborhood and didn’t know what was going on.”

Father Lu’s face was also a little embarrassed, trying to perfunctory this topic.

But how could Aunt Wang’s family believe such nonsense!

The guard standing guard at the gate of this community is not an ordinary security guard, it is a serious army! You wander around, can you go inside, and people still don’t stop you?

Ghosts believe!

However, although Aunt Wang did not believe what Father Lu said just now, they couldn’t say where they should refute it!

Oh, yes.

If they’re not shopping around, how do they get in?
