Chapter 125 How the hell is this possible?
After leaving the club, Su Hao did not return to his dormitory, but went straight to the information science section of the school library.
What an absolutely fascinating language!
Having completely mastered programming, his terrifying logical reasoning ability...
He already knew precisely which areas of knowledge he needed to acquire in order to perfectly solve this multi-objective laundry room game problem.
He wandered among the bookshelves, pulling out three thick volumes without hesitation:
Operating Systems and Process Scheduling
Computer Networks
Game Theory and Algorithm Design
Go back to dorms.
As night fell, only the faint chirping of insects could be heard outside the window.
Su Hao laid out the heavy books and densely packed draft notes on his desk and opened the laptop screen.
hum-
The cooling fan emitted a soft buzzing sound.
"Alright, let's begin. Let me see how far you can go." Su Hao's eyes narrowed slightly.
Tap tap. Tap tap.
Fingers tapped on the keyboard, producing a crisp rhythm.
First, we build the overall framework of the underlying algorithm.
In his mind, those vast and complex mathematical theories, like stars in the night sky, kept flashing and appearing...
He then precisely removed it and transformed it into lines of highly ordered code on the screen.
Tap tap, tap tap, tap tap tap...
As night deepened and all was quiet outside the window, the sound of typing on the keyboard became more and more continuous and frequent.
"Having a basic framework isn't enough; what other conditions are needed to restrain the students' hooligan behavior?"
He began to try to integrate several ingenious ideas he had gleaned from books directly into this small laundry room app.
To prevent a large number of students from making appointments during peak periods, which could cause server crashes and permission conflicts, he directly introduced a [random delay simulation module] based on Poisson distribution at the underlying level.
To deal with the "ghost calls" that were causing a lot of complaints on the forum—calls that were scheduled but never showed up—he manually created a cold and ruthless set of "instant response event handlers."
"Punishment alone isn't enough; we also need to introduce a compensation mechanism!"
Su Hao became more and more excited as he wrote, and his typing speed increased.
He established a "credit score model" in the background, using the incentive mechanism principle in game theory to subtly regulate and guide the behavioral choices of all students in the school.
Not coming to wash? Credit score deducted!
Washing late at night? Earn credit points!
Credit scores directly affect the weighting of the queue allocation!
After completing the final line of code for the preliminary design, Su Hao breathed a sigh of relief and smiled with satisfaction as he looked at the perfectly running simulation program on the screen.
......
three days later.
"Bit Forge" event room.
Su Hao seemed like a completely different person.
If a week ago he was a newbie staring blankly at code, now he's a tyrant on the keyboard!
Tap tap tap tap tap tap—!
The rapid clatter of keyboard keys, like a violent storm, relentlessly echoed throughout the room.
On the screen, dazzling code modules cascaded down like a waterfall.
Standing behind him, Li Xiangyu was staring intently at Su Hao's screen, cold sweat dripping down his forehead. He was completely dumbfounded!
Although Li Xiangyu may appear to be just an unkempt teenage student, he is, after all, a veteran with many years of practical development experience and has won numerous national-level Olympiad awards in informatics!
But at this moment, facing the algorithm logic written by Su Hao, he actually felt a kind of despair, as if his intelligence was being brutally rubbed into the ground!
"Holy crap! Holy crap!! How the hell is this possible?!"
He only learned what Python was a week ago!
Li Xiangyu felt that his worldview was collapsing.
Su Hao's long, slender, and fair fingers danced nimbly across the mechanical keyboard, each keystroke executed without the slightest pause or hesitation, his posture resembling that of a conductor performing a grand symphony on the black and white keys of a piano...
That kind of sophisticated and oppressive aura was so overwhelming that even the "veteran" Li Xiangyu didn't dare to breathe.
squeak-
The door was pushed open.
"Are you ready? How far along are we?"
Fang Jun and Liu Jie walked in, their foreheads covered in sweat, their voices filled with anxiety.
Upon hearing the sound, Su Hao stopped what he was doing, turned his chair around, and faced the people in the room who were holding their breath.
Without any pleasantries or boasting, he spoke in a calm, matter-of-fact tone:
"The derivation process is a bit complicated, so to save everyone's time, let's start with the conclusion."
That calm and authoritative aura made the two student council presidents and vice presidents pause involuntarily for a moment.
Then, as if by reflex, he pulled out his notebook and prepared to take notes like a primary school student listening to a lecture.
"First of all, in the complex distribution of social resources, absolute and perfect fairness does not exist in reality."
Su Hao spoke slowly, his tone carrying a profound philosophical quality.
"However... we can adjust it through game theory algorithms to achieve a dynamic equilibrium state where 'although not absolutely equal, no one will feel obviously disadvantaged.'"
In the intersection of advanced mathematics and game theory, this is known as EF1, which stands for Envy-Freeness up to one item.
"...EF1?" Fang Jun paused, looking completely bewildered.
What alien language is this?
Su Hao turned the monitor around.
Instead of dry code, the screen displays a series of densely packed dynamic charts and big data simulation results.
"Yes. Simply put, it's due to the system's extremely fast calculations..."
If any student makes even the slightest concession under the system's allocation, such as accepting a slightly less popular time slot, the system will provide them with extra compensation in the next booking.
Through such precise calculations, the "sense of inequality" between people tends to be smoothed out in mathematical models.
In the long run, everyone has an absolutely equal chance of getting the prime time slot!
At the same time, because the conflict is eliminated, the washing machine's operating efficiency can be maintained at its peak, preventing situations where the machine is completely empty at night and people are scrambling to buy it during the day.
Li Xiangyu's pupils suddenly contracted. He jerked his face closer to the screen, almost pressing it against the charts, his voice cracking with shock:
"This...this level of academic theory, can it really be implemented on an app in our run-down laundry room?"
He felt like he was going crazy.
Others might not know, but how could a seasoned competitor like him not know?
This is clearly an incredible problem that even top university professors and their teams might struggle to solve when writing a top-tier paper!
The boy in front of me was talking about what to order for lunch with such nonchalance!
"What's so difficult about that?"
Su Hao shrugged, his Versailles-esque nonchalance only driving people crazy.
"So-called fairness can be dynamically adjusted at the underlying level through probability weighting functions and credit compensation structures."
By combining these two elements using a specific matrix, we can naturally balance efficiency and fairness under rational conditions. It's very simple.
It's very simple.
It's very simple...
Li Xiangyu was so angry that she burst out laughing, and tears of despair even welled up in her eyes:
"Dude, you actually used the god-level EF1 algorithm to manage a dilapidated laundry room with only ten washing machines?!"
What's the difference between this and using a nuclear bomb to kill a mosquito?!
The male student next to him, who had been slumped in his chair with headphones on for the past few days, suddenly sat up straight as if electrocuted, his headphones falling onto his collarbone.
"Holy crap... if this scheduling model really works, we could just slap on some fancy shell and enter it into national or even global programming competitions, winning the grand prize would be a piece of cake!"
"From an engineering perspective, it is indeed extremely difficult, but as long as the logic is sound, it is entirely feasible and has great practical significance."
Of course, this is all predicated on the developers of this algorithm possessing mathematical mastery that surpasses everyone else's; ordinary people shouldn't even dream of it!
Zhang Man, sitting in the corner, pulled up the brim of her hat, her face filled with the fanaticism of a believer witnessing a miracle, staring intently at Su Hao, who was sitting in a chair glowing.
The room fell into a deathly silence.
Only the whirring sound of the host fan echoed.
Fang Jun and Liu Jie, completely dumbfounded, were staring blankly at the complete set of visual simulation charts prepared by Su Hao.
In the accelerated simulation, 10 washing machines and 12 dryers are operating in perfect synchronization and high efficiency, like precise clock gears.
The bar chart next to it, representing the queuing sequence, is being precisely cut, divided, and rapidly shortened by the algorithm, much like a scalpel.
Meanwhile, the scarlet block in the lower right corner of the screen, representing the "unfairness resentment index," is rapidly dissipating and dissolving under the suppression of this algorithm, eventually stabilizing at an extremely low level close to zero.
"After the rectification... the overall average waiting time was reduced by a whopping 45%?"
Liu Jie stared at the glaring data, his voice echoing in the silent room.
The surroundings were completely silent.
No one answered him, because everyone's defenses had been completely shattered by this number!
"As expected of our Duck God!!"
Zhang Man crossed her arms and exclaimed in utter admiration.
