Reborn in 2011, I am the chief designer of aerospace.

When Jiang Mian and Zhao Yuehe returned, huffing and puffing, carrying a stack of documents, they didn't complain at all. The latter said with a look of excitement:

"Done! Registration successful, our four-person team is officially formed!"

Cotton stared at Song Xingye with sparkling eyes.

Song Xingye nodded: "Next, let's arrange the division of labor. We need someone to be in charge of the software architecture and computing power allocation. This person will not only build the simulation framework but also get the physical model running."

The key is to be proficient in C++. While Python is good, it's too slow when dealing with massive amounts of data.

Chang Jian volunteered, saying, "I'll take charge of the software architecture!"

Neither the cotton plant nor the lotus flower made a sound, so Song Xingye nodded.

Who is better at math?

Zhao Yuehe immediately pushed Jiang Mian forward, "Mianhua's math skills are absolutely amazing!"

Song Xingye glanced at Jiang Mian: "Beam search, genetic algorithm, ant colony algorithm, and Monte Carlo tree search—can you get started?"

Jiang Mian nodded vigorously, as if pounding garlic: "Not only that, I can also..."

"That's enough."

Song Xingye interrupted her, "You will act as the team's 'mathematical brain.' The difficulty in orbit design lies in finding the optimal solution among hundreds of millions of possibilities."

Your task is to "translate" the physical model I proposed into mathematical language. After finding the rough trajectory, use a global optimization algorithm to refine it to be smooth and precise.

"If we could write heuristic search code by hand, the efficiency would be even higher..."

After Song Xingye finished speaking, he pointed to himself:

"I won't be modest; I'll take on the role of the team's core physics brain. I'll quickly grasp the physical models and astronomical methods given in the problem, and translate the Kepler orbit and Lambert problem into executable physical language."

The three of them had already assigned tasks.

Those good at physics can handle mechanics, those good at mathematics can handle algorithms, and those good at coding can handle architecture...

Finally, the gaze fell upon Zhao Yuehe, who had not yet received her task.

"Lotus, your task is rather complicated, but equally important."

Song Xingye explained clearly: "You need to write a script to convert the trajectory we calculated into a visual 3D animation; at the same time, write a set of 'attack code' specifically for finding flaws and checking whether the trajectory meets all the constraints of the problem."

"Furthermore, the final writing and polishing of the document will also be entirely your responsibility. The quality of the paper will directly affect Mr. Liang's impression of you."

"We only have five days. The first day was for modeling, the second for searching, the third for architecture, the fourth for optimization, and the fifth for report writing. Everyone understands their responsibilities, right?"

Song Xingye arranged everything meticulously, exuding an undeniable leadership aura.

Everyone felt reassured and immediately nodded without any objection.

The battleground then shifted from the multi-functional hall to a huge conference room marked "Collaborative Design Center".

This is a semi-circular, tiered hall with a huge, seamless video display screen directly in front. The anti-static floor makes a creaking sound when you step on it.

Inside the walls of the conference room, the faint hum of the air conditioner could still be heard.

According to Li Ang, this is the group's newly built high-end computer room, which has not yet been officially put into use, but these students have already gotten there first.

Rows of long tables are arranged in an island-like pattern, with frosted glass walls separating each team, ensuring excellent privacy.

Four people sat around a table, with several graphics workstations in front of them, each equipped with a monitor.

Each person's temporary pass number is their workstation account.

Zhao Yuehe asked in confusion, "There's only a screen here, no main unit? Is this an all-in-one design?"

Chang Jian, who seemed quite knowledgeable, said, "You're quite ignorant about this. This is a cloud desktop specifically deployed to prevent data from being copied."

Can you hear the air conditioner fan next door? The servers are all locked in that server rack.

Moreover, these computers cannot connect to the internet; they are completely physically isolated from the outside world. If you want to download external data, you can only use your own computer or mobile phone…

Zhao Yuehe suddenly realized, and nodded with a sense of awe despite her confusion.

Once the equipment was debugged, the four of them immediately gathered together and began their first brainstorming session.

Song Xingye took the lead, while the other three filled in the gaps.

From satellite system parameters to orbital dynamics models, and then to the data link of the relay satellite...

Before long, the whiteboard next to him was covered with Lambert's equations, velocity vector diagrams, and various obscure physical symbols.

Chang Jian and Zhao Yuehe were struggling to follow along, while Jiang Mian not only kept up with the train of thought but also occasionally added a brilliant comment.

This feeling gave Song Xingye the thrill of a teacher encountering a genius student.

"That's roughly the logic, do you understand?"

Song Xingye asked a question out of habit, not expecting everyone to understand, and then decisively flipped the whiteboard over.

"Next, we'll analyze the constraints: initial state constraints, mission duration constraints, maneuverability constraints, altitude constraints, observation field of view and solar altitude angle constraints, and data transmission constraints. These are the six major constraints that determine the score..."

Next came another intense brainstorming session.

This time, even Jiang Mian found it a bit difficult to understand...

"In summary, the initial orbital altitude is tentatively set at 350 kilometers, and the fuel load is 250 kilograms."

"For optical stars to be used for reconnaissance, the solar elevation angle must be greater than 20° to avoid interference; infrared stars do not have this limitation."

"Since the 200 ground targets are scattered, dynamically adjusting the orbital altitude within the range of 200 to 500 kilometers during each round of reconnaissance should be able to bring all targets into the reconnaissance range. Specific strategies will be discussed later."

After finishing his explanation in one breath, Song Xingye turned around, still feeling unsatisfied, and put down his whiteboard marker: "Do you understand now?"

"Emmm..."

"Well……"

"Huh? That's it?"

Chang Jian couldn't help but complain, "Hoshino, were you so engrossed in your own artistic world just now that you couldn't pull yourself out? I felt like I was listening to gibberish!"

"Is it really that exaggerated?"

Song Xingye smiled and continued, "Let's start designing along these lines. Jiang Mian and I will work on the physical/mathematical models, and Chang Jian will work on the integrators for the J₂ perturbation model and the atmospheric drag model."

Zhao Yuehe should quickly convert the six orbital roots into position and velocity vectors, and write a set of equations to calculate the conversion relationship between latitude and longitude and position vectors. We can communicate anytime if there are any problems…”

As soon as he finished speaking, everyone got to work.

Song Xingye and Jiang Mian sat close together, discussing quietly in a corner.

Jiang Mian blinked and said cutely, "Song Shen, your aura today is really different from before!"

"Can you feel the overwhelming aura of dominance emanating from the top student at Jiaotong University?"

"No..." Jiang Mian paused for a moment, seemingly organizing her thoughts.

"It's just... I feel like Song Shen exudes a leader's aura, and he naturally assigned everyone their tasks and responsibilities. If it were me, I'd probably struggle with it for ages..."

Song Xingye thought about it and realized it was true.

Perhaps it's a habit formed from being a chief engineer in a past life; subconsciously, I want to take charge of the overall work and handle everything.

So he laughed and said, "Then you should follow along and learn from her; maybe you can become a female chief engineer someday."

"Goose, goose, goose..." Jiang Mian was amused and laughed out loud.

Today she was wearing a loose T-shirt, revealing her slender, white, and straight long legs, with her hair tied in a loose ponytail. When she smiled, she looked like a complete naive and sweet girl.

However, as it turns out, Chief Engineer Song misjudged the situation this time.

This young girl is far from being just a pretty face with a rotten core; she's actually quite capable!

In daily discussions, her opinions were exceptionally accurate, and her sharp and profound thinking quickly changed Song Xingye's impression of her.

In particular, Jiang Mian always manages to ask some very crucial and complex questions that get straight to the point. Although Chang Jian and Zhao Yuehe next to her are completely confused, Song Xingye is very satisfied.

Girls with such extensive knowledge, excellent memory, and a thirst for learning are rare indeed...

"Playing dumb to fool others? Or is he a hidden gem?"

Song Xingye leans towards the latter.

Although her overall performance at this summer camp was unremarkable.

But when it comes to mathematical talent alone, he admits that this girl is absolutely second to none!

What's even more remarkable is that she is not only smart, but also obedient and hardworking.

Song Xingye asked her to focus on studying genetic algorithms. Without hesitation, she quickly collected all the information related to genetic algorithms and systematically read and absorbed it.

With such a smart and capable little helper, Song Xingye felt as if he had wings.

I thought it was one god leading three fools, but now it seems there's another 'false god' added.

In the following days, Jiang Mian's performance repeatedly pushed the limits of Song Xingye's understanding.
