Awakening Elementary School System in University

"President Chen," Zhu Jianqing began, a warm smile on his face, "I wonder, do you have any brilliant insights into our problem?"

In an instant, every eye in the conference room focused on Chen Lin.

Hearing his name, Chen Lin unhurriedly raised his head.

He first glanced at Professor Gongtan, who was beaming at him, as if nodding a silent greeting. Only then did he turn his gaze to Zhu Jianqing and say in a relaxed tone:

"Yes, I do have an idea. You could call it a complete solution."

As his words fell, the room was instantly silenced.

What followed was a variety of reactions.

You Lie and Lv Yi’s eyes first widened in astonishment, then, almost in unison, unconcealed mockery crept onto their faces.

’Is he crazy?!’

’He actually said he has a complete solution?’

’Does he even know what he’s talking about? What an absurd boast!’

They were almost certain the kid was just trying to show off in front of his crush and the company chairman, forcing himself into the spotlight!

Meanwhile, Professor Gongtan still wore his cheerful smile, but a shrewd, almost imperceptible glint flashed in his narrow eyes.

Yan Feifei and Zhu Jianqing exchanged a look. She even found herself subconsciously wondering if she hadn’t explained something clearly, simplifying the problem and giving this young man the false impression that it was simple.

Zhu Jianqing, however, maintained his steady smile and simply made a "please continue" gesture toward Chen Lin.

"I’m all ears."

"Well, about that..."

A perfectly timed embarrassed look appeared on Chen Lin’s face. He scratched his head and said, "Chairman Zhu, my solution is a complete concept that’s ready for immediate implementation. If I were to lay it all out right here and now, that would constitute a formal technical consultation for your company."

At these words, the conference room fell silent once again.

No one had expected him to make such a demand at this critical juncture.

The mockery on You Lie and Lv Yi’s faces deepened. ’There it is! He’s showing his true colors now,’ they thought. ’He doesn’t know anything at all and is just trying to be mysterious to find a way to back down!’

However, before Zhu Jianqing could speak, Professor Gongtan, who was sitting to the side, burst out laughing.

He pointed at Chen Lin and said to Zhu Jianqing, overcome with mirth, "Old Zhu, listen to him! The kid is finding a roundabout way to ask you for money!"

Zhu Jianqing was taken aback for a moment, then he too erupted in laughter, his hearty chuckles echoing throughout the conference room.

"Hahaha, interesting! Very interesting!"

With a grand wave of his hand and the magnanimous air of someone for whom money was no object, he declared decisively, "No problem! Dr. Yan and Professor Gong are both here as witnesses today. As long as your solution gets a nod of approval from them, I’ll pay you on the spot!"

"Perfect."

That was exactly what Chen Lin wanted to hear.

Wasting no more words, he stood up decisively, walked to the large electronic whiteboard at the front of the room, casually picked up a black marker, and uncapped it.

In that instant, his entire demeanor changed.

The relaxed, casual air of a university student vanished, replaced by an extreme, calm focus.

Without the slightest hesitation, he wrote the core title of the solution at the very top of the whiteboard.

[Modeling "Dynamic Enrollment Threshold Adjustment" as a Constrained Markov Decision Process (CMDP) with Probabilistic Constraints]

This title alone was enough to make both Yan Feifei’s and Professor Gongtan’s eyes light up.

Following that, Chen Lin began to write, his movements as smooth as flowing water.

He didn’t get bogged down in a single theoretical difficulty like You Lie and Lv Yi had. Instead, he approached it directly from a top-level design perspective, presenting a single optimal approach that was "ready for immediate implementation."

"...The core method is: use a differentiable enrollment policy, with the ’posterior predictive probability of end-of-trial success’ as the efficacy objective. Treat Type I/II errors as hard constraints using a Lagrange multiplier, and find the optimum for the entire system via a two-timescale dual optimization..."

As Chen Lin wrote, he provided a verbal explanation in concise language.

His pace wasn’t fast, but every word was perfectly clear, and his chain of logic was seamless.

At first, the dozen or so people in the conference room could just barely follow his train of thought, their faces etched with concentration.

But as the formulas and symbols on the whiteboard grew increasingly complex, more and more people started to fall behind.

The researchers from Huanrun Pharmaceutical were the first to show looks of bewilderment.

Next were You Lie and Lv Yi.

The mockery on their faces had vanished without a trace, replaced by a deepening shock and a growing paleness.

They realized that every concept Chen Lin mentioned, every module he constructed, struck precisely at the core of the problem. Furthermore, his problem-solving approach was far beyond the scope of their understanding!

By the time Chen Lin was halfway through, the only ones in the entire conference room who could fully keep up with his line of reasoning were Dr. Yan and Professor Gongtan.

And when Chen Lin began to explain how to use "primal-dual safe reinforcement learning" to jointly optimize the entire decision-making process in one go, even Yan Feifei’s brow furrowed tightly, her face showing a look of intense and strained concentration.

Finally, by the time Chen Lin had listed out the entire solution’s "minimum implementation checklist," the only person in the room who could still effortlessly follow every detail of his derivations was Professor Gongtan.

SQUEAK... SQUEAK...

The sound of the marker gliding across the whiteboard was the only sound in the entire space.

Time passed, second by second, minute by minute.

Finally, after nearly fifty minutes, having filled both the front and back of the entire whiteboard, he made his final stroke.

CLICK.

He capped the marker, tossed it aside, and turned to face the somewhat stunned Zhu Jianqing. "All done," he said lightly.

Zhu Jianqing snapped back to his senses. He didn’t look at the incomprehensible symbols on the whiteboard; instead, his gaze immediately shot to the two experts beside him.

He saw that the faces of both Yan Feifei and Professor Gongtan wore expressions of unprecedented gravity and seriousness.

"Well?" Zhu Jianqing’s voice held a hint of barely perceptible tension.

Dr. Yan took a deep breath and slowly shook her head. A wry smile touched her lips as she admitted frankly, "Chairman Zhu, forgive my bluntness, but the theoretical depth and computational complexity of this solution are beyond what I can immediately assess... I’m not confident I can."

HISS—

A collective gasp echoed through the conference room.

If even Dr. Yan, Huan Run’s number one technical expert, wasn’t confident, then the value of this solution was simply unimaginable!

Everyone’s gaze finally converged on the last and most authoritative judge—Professor Gongtan.
