They're already in university, and the primary school system is only just starting out?

Chapter 106 This company is so good-looking!

At this point, he couldn't help but chuckle, waving his hand and saying in a half-joking tone, "At worst, if this project doesn't go through, consider this ten thousand yuan as me paying for a ticket to a top-notch academic performance. It's a good deal!"

Luo Qin:

Goodness, is the world of the rich really this simple, unpretentious, and boring? Luo Qin mentally ranted.

To satisfy his curiosity, he casually tossed out 10,000 yuan without even blinking.

That makes sense, Luo Qin thought silently. For someone who earned nearly two million last year from salary and stock dividends alone, ten thousand yuan is probably about the same as spending one hundred yuan to buy a new mouse.

After all, his boss and mentor was a complete tech fanatic; otherwise, he wouldn't have been able to become the vice president of R&D before he was even forty.

Seeing that Luo Qin had stopped talking and had obviously accepted his explanation, Tao Wei picked up his phone again, dialed Sun Yu's number, and called him directly.

The call was answered quickly, and Tao Wei didn't waste any time, getting straight to the point: "Xiao Sun, right? This is Tao Wei from Chuangjiyuan. Send me your testing service contract now, I'll sign it immediately."

After saying that, he simply hung up the phone.

Less than half a minute later, his mobile email received a PDF file with a "ding".

Tao Wei forwarded the document to his work computer and printed it out directly. He took a pen from the pen holder, glanced at the details of the contract, then turned directly to the last page and signed his name in a flamboyant manner.

After signing, he tossed the contract aside and instructed Luo Qin, "Scan it and send it back to them. Then file the original."

"Okay, Mr. Tao." Luo Qin responded immediately, picked up the contract, and walked towards the multifunction printer in the corner of the office.

Scanning, emailing, and archiving of original documents – the entire process flows smoothly.

After dealing with these matters, Tao Wei directly instructed Luo Qin: "Notify the finance department to transfer 10,000 yuan to Yanhai Company right now, through the expedited channel."

"Okay, Mr. Tao."

Luo Qin immediately accepted the order and turned to leave the office.

Just a few minutes after the money was transferred, as if timed perfectly, a brand new email appeared in Tao Wei's inbox right on time.

The attachment contains several image files with simple and straightforward filenames—"[Genesis Test Questions and Solutions]".

"The efficiency is quite high."

Tao Wei muttered to himself, a hint of anticipation on his face, and moved the mouse to open the email.

Several high-resolution photos taken with a mobile phone immediately filled his computer screen.

The background of the photo appears to be a brand-new desk, while the subject of the photo is several A4 sheets of paper filled with writing.

The handwriting is bold and unrestrained, yet every mathematical symbol and letter is written clearly and distinctly, without affecting readability in the slightest.

Tao Wei's gaze slowly moved downwards from the first line of formula.

Initially, his expression held a hint of scrutiny and curiosity, but as he read on, that composure gradually disappeared, replaced by an increasingly solemn seriousness.

When he saw the three error function models presented by Chen Lin, especially the last neural network model that he had directly created by hand, he even subconsciously sat up straight, staring intently at the screen, and his breathing became somewhat rapid.

Luo Qin had just finished communicating with the finance department when he pushed open the door and walked in, only to see his boss looking like he was facing a major crisis.

His heart skipped a beat, and he quickly stepped forward, asking with concern, "Mr. Tao, what's wrong? Is there a problem with their answer?"

Did something go wrong? Was that college student who seemed so arrogant in the video actually just a show-off?

Tao Wei didn't answer him; he simply reached out and quickly made a few moves on the computer.

The multifunction printer that had been quietly waiting in the corner of the office immediately started working with a slight buzzing sound.

A few seconds later, several sheets of A4 paper, still warm, slowly slid out of the paper output slot.

The above printout is Chen Lin's solution process.

"Take this," Tao Wei said, looking up at his assistant intently, "and show it to Lao Fan right away."

Lao Fan, also known as Fan Jianjun, is the chief algorithm engineer in the R&D department of Chuangjiyuan Technology, and is recognized as the top technical expert in the department.

"OK!"

Although Luo Qin was filled with doubts, he readily agreed, picked up the papers, and quickly walked out of the office.

Tao Wei's office fell silent once again.

He didn't look at the solution process on the screen anymore, but slowly leaned back in his chair and let out a long sigh.

He finally understood why Peng Yifeng had used such a "struck gold" tone when recommending this little-known company to him.

Less than ten minutes.

"Bang!"

The office door was pushed open from the outside, slamming against the wall with a loud bang.

A middle-aged man in his forties with thinning hair rushed in like a gust of wind, clutching the few printed papers tightly in his hand. His face was filled with a complex expression of shock, ecstasy, and disbelief.

It was Lao Fan.

-

Seeing his flustered appearance, Tao Wei smiled and leisurely picked up his teacup, teasingly saying, "Old Fan, what's the big deal? You almost broke the door."

"Absolutely! Absolutely!" Old Fan rushed to the desk, slamming the papers down with a "thud," his voice trembling with excitement. "Old Tao! Tell me! Which department in the group wrote this?! Damn, he hid it so well! Get him here immediately, right now, to report to our software development team!"

Seeing Lao Fan's eagerness to snatch the man away, Tao Wei's smile deepened.

He slowly sipped his tea, then shook his head and said, "You're overthinking it. He's not one of our company's employees."

"No?" Old Fan was taken aback.

Then, Tao Wei recounted to Lao Fan the whole process of how he found the consulting company called "Yanhai" through Peng Yifeng's connections, how the company proposed the testing fee, and how he received the answer.

After hearing this, Lao Fan stood there dumbfounded for a full half minute before he finally digested this outrageous information.

He picked up the draft on the table, looked at it again, and muttered to himself, "Genius—this is the real genius—"

Tao Wei put down his teacup, looked at his tech expert, and asked with a smile, "So, Lao Fan, how about coming with me to Tianjin?"

"go!"

Lao Fan agreed almost without hesitation, his tone resolute.

"I want to see for myself what kind of monster wrote this!"

October 8th, Thursday.

Tianjin International Airport, Domestic Arrivals Exit.

"Mr. Tao, welcome, welcome!"

With a warm smile on his face, Sun Yu took a step forward to greet the group of three who had just walked out of the gate.

Chen Lin followed beside him, a warm smile on his face, neither humble nor arrogant.

"Haha, Xiao Sun, President Chen, thank you for making this trip in person." Tao Wei laughed heartily and shook hands with the two men.

He then turned to the side and began to introduce his companions to the two men.

"This is my assistant, Luo Qin." He pointed to the sharp-looking young man wearing black-rimmed glasses.

"This is Fan Jianjun, our chief algorithm engineer in the software R&D team." He then pointed to the middle-aged man next to him with slightly balding hair but unusually bright eyes.

"Hello, Mr. Chen. Hello, Engineer Fan."

Luo Qin nodded politely, but his gaze involuntarily fell on Chen Lin, with an undisguised curiosity and scrutiny.

From his appearance, isn't he just an ordinary male college student who is just a little more handsome?

He was dressed in a simple T-shirt and jeans, with a tall and straight figure, a clean and neat demeanor, and a hint of youthful energy still lingering on his face.

No matter how you look at it, it's hard to connect it with the image of that genius who could write out a solution process that even Lao Fan found amazing in just over ten minutes.

The group boarded a pre-arranged business vehicle and headed towards Yannan University.

The car eventually stopped in front of the student co-working space building.

When Chen Lin led Tao Wei and his group into the huge office on the second floor, both Tao Wei and Luo Qin showed a hint of surprise on their faces.

They assumed that a newly established college student startup company would have its office located in a small cubicle of a few dozen square meters, even if it wasn't in a dormitory.

But the place in front of them was several hundred square meters, spacious and bright, with clean windows and tables. Brand new desks and chairs were arranged in a neat and orderly manner, and the whole space was well-organized, which did not look like what a startup team should look like.

"Mr. Chen, your office environment is quite impressive," Tao Wei exclaimed sincerely.

Chen Lin smiled and attributed the credit to others: "This is all thanks to our Assistant Huang. I was just a hands-off manager."

As he spoke, he led the group inside and introduced them to the other two veterans in the office.

"This is Huang Yiyi, the executive assistant to our company's president."

Upon hearing the commotion, Huang Yiyi, who was working on documents at her workstation, immediately stood up, gave the visitors an impeccable professional smile, and nodded slightly: "President Tao, Mr. Luo, Engineer Fan, welcome."

Tao Wei's gaze lingered on Huang Yiyi for a moment, a hint of surprise flashing in his eyes.

Goodness, that demeanor, that speech, that professionalism—even at the headquarters of their Genesis Group, that would be considered elite level.

"This is Shen Yan, an intern at our company and a top student in the Mathematics Department of Yannan University."

Chen Lin then pointed to the other side.

Shen Yan, who was wearing headphones and quietly reviewing a client's file, took them off and stood up. She nodded shyly to the guests and said softly, "Hello."

Luo Qin's eyes widened instantly.

Wow, isn't the company's level of attractiveness a bit too high?

However, his little grumbling was quickly dispelled by the serious atmosphere that followed.

Guided by Huang Yiyi, the group arrived at a long table temporarily made up of two desks and sat down on either side.

Huang Yiyi then brought several more cups of warm water for the guests.

After a brief exchange of pleasantries, Chen Lin didn't want to waste any more time. He leaned forward slightly, looked at Tao Wei opposite him with a confident smile, and said bluntly, "Mr. Tao, let's not beat around the bush. You can talk about the problems you're facing now."

Upon hearing this, a hint of appreciation flashed in Tao Wei's eyes.

He likes dealing with people who are decisive and efficient.

He nodded and winked at Luo Qin beside him.

Luo Qin immediately understood, opened his laptop, adjusted the angle, and pushed it to the center of the table.

At the same time, Fan Jianjun, who hadn't said much, cleared his throat, and his bright eyes instantly lit up.

He looked at Chen Lin and spoke in a deep voice, personally explaining to Chen Lin the core bottleneck that Chuangjiyuan was currently encountering in industrial software using mathematical methods.

"Mr. Chen, it's like this."

Fan Jianjun's voice was not loud, but his pronunciation was clear and his logic was rigorous, with every word exuding professionalism.

"In high-end CNC machining, especially in the five-axis linkage machining of complex curved surfaces, in order to pursue efficiency and quality, the tool's motion trajectory must achieve two things: first, it must be absolutely smooth; second, it must never exceed the dynamic limits of the machine tool itself."

He held up two fingers and gestured: "But that's where the problem lies. The original path we export from the CAD software is essentially a series of discrete points. The path formed by these points is often not smooth at the turning points, and the acceleration will change abruptly."

If a machine tool were to actually run along this path, the intense vibrations and impacts would instantly destroy expensive cutting tools and even the spindle.

Therefore, we must smooth out this original path at the software level to generate a new path, at least a C2 path.

Continuous, meaning a smooth trajectory in which position, velocity, and acceleration are all continuous.

"But that's not all." Fan Jianjun's expression became increasingly serious. "A smooth trajectory isn't enough; we also need to plan how the cutting tool will move along that trajectory," which is what is known as speed planning.

Because the speed, acceleration, and even jerk of a machine tool have physical limits. You can't make it accelerate from a standstill to 10,000 revolutions per minute in 0.1 seconds; that's unrealistic.

At this point, he sighed deeply, his tone filled with helplessness and resentment: "And this is precisely where the biggest gap lies between us and that 'Himmon' from the Hans Kingdom." Their NX software can perfectly integrate trajectory smoothing and dynamic constraints into a single optimization framework, calculating paths that are both fast and stable.

Our software either sacrifices speed to ensure quality, or sacrifices yield to pursue speed. We can never achieve the best of both worlds.

Luo Qin, who was standing to the side, had already opened the prepared PPT on his laptop. The PPT used clear charts and formulas to visualize the problem that Fan Jianjun had mentioned.

Finally, Fan Jianjun's gaze was fixed on Chen Lin, and he spoke slowly and deliberately, revealing the true purpose of their trip: the core problem that had plagued their entire team for years.

"Therefore, we hope that you, Mr. Chen, can help us design a mathematical optimization framework."

"Given an initial toolpath defined by N discrete points, and the maximum permissible speed Vma, acceleration A-ma, and jerk J-ma of each axis of the machine tool."

"Your task is to generate a new, smooth toolpath that meets the three strict constraints of geometric accuracy, C2 smoothness, and dynamics, and to find an optimal motion law to ultimately achieve the goal of minimizing machining time or machine tool impact."

"We need you to explain the entire optimization framework, focusing on: how to parameterize the smooth path and motion laws? How to transform discrete geometric constraints and highly nonlinear dynamic constraints into joint constraints on path parameters and motion parameters? And finally, what are the optimization variables, objective function, and constraints of this optimization problem?"

After he finished speaking, the office fell silent.
