Chapter 34 Algorithms for 9-Digit Values
Gu Feiyu crushed the chalk in his hand. "I hope you'll still be this confident on the day of your defense."
Xia Zijing sat beside her, flipping through the requirements on the project outline, and lowered her voice. "The amount of data is enormous. Your algorithm model has only run the core logic so far; it still requires a lot of engineering code to implement it. I can only calculate physical quantities; I don't know how to write this kind of low-level engineering architecture."
"I know."
Lin Yu stood up and walked out of the classroom. "So we need to hire someone for manual labor. The computer science students should really like this kind of thing."
Two weeks later. Physics Department, Jinghua University, Defense Room No. 1.
The audience was filled with students. The judges included the department head, three senior professors, and Gu Feiyu, as a student representative, was responsible for recording the scores.
The first few freshmen presentations were rather conventional, showcasing standard mechanics models or thermodynamic calculations. The professors were starting to drowsiness.
"Next group, Lin Yu and Xia Zijin."
Gu Feiyu gripped his pen tightly, staring intently at the two people walking onto the stage. He had specially invited several professors known for their strictness today, precisely to thoroughly critique Lin Yu.
Lin Yu walked onto the podium. He didn't bring a heavy paper report or a fancy PowerPoint presentation.
He only had a black USB drive in his hand.
"Let's begin."
The department head tapped on the table. "Regarding the compressed transport of massive amounts of microscopic particle states, where is your model located?"
Lin Yu directly plugged the USB drive into the computer on the podium.
The large screen lit up. There were no formulas, no derivations, only an extremely rudimentary black-framed user interface.
"I didn't write a model."
Lin Yu leaned on the podium with one hand, speaking steadily, "Theoretical derivation is a waste of time. I just made something."
Gu Feiyu immediately retorted, "Lin Yu! This is a physics final defense, not a computer class assignment! You haven't even written out the basic physics equations; are you trying to fool the judges?"
Lin Yu didn't even glance at him. He typed a few words on the keyboard.
"This is a raw data package of particle collisions that the Large Hadron Collider in Europe released last year."
Lin Yu pointed to the file properties on the screen, "The size is 500GB. It contains the motion trajectories and quantum states of hundreds of billions of particles."
The professors in the audience frowned. 500GB of data would crash an ordinary computer just trying to read it.
Lin Yu opened the black program box, which was less than 2MB in size, and dragged the 500GB data package directly into it.
"Start compression."
Press the Enter key.
The progress bar on the screen didn't climb forward little by little, but rather seemed to teleport. Ten seconds. Just ten seconds. The progress bar was full.
The original 500GB data package disappeared, and a new file with the .qd extension appeared on the desktop.
Size: 4.8GB.
The defense room was so quiet you could hear a pin drop.
"That's impossible!"
Gu Feiyu suddenly stood up, pointing at the screen, "Compression rate over a hundred times? And that's without damaging quantum state information? You've absolutely brute-forced data deletion! This kind of forgery is too low-level!"
Several professors also looked doubtful. The current limit for lossless compression is only a few times; a hundredfold compression violates the basic law of information entropy.
"Whether it's fake or not, you'll know once you unzip and verify it."
The door to the defense hall was pushed open. Academician Zhang Chengzhi strode in; he had been passing by but was drawn in by the commotion.
Zhang Chengzhi walked directly to the front of the class, staring at the screen: "Unzip it. Run a hash value verification."
Lin Yu shrugged and pressed the decompression button.
Two minutes later, the file size was restored to 500GB. A hash value comparison result pop-up window appeared: 100% match. Zero packet loss, zero distortion.
Gu Feiyu's face instantly turned pale, his legs went weak, and he fell heavily back into the chair.
"What...what mathematical tools did you use?"
Zhang Chengzhi grabbed Lin Yu's wrist, his voice trembling. He had figured it out; this was definitely not any existing algorithm.
"Topological manifold folding".
Lin Yu spoke calmly, as if he were talking about what he had eaten that day, "Think of data as particles in a higher-dimensional space. You compress volume in three-dimensional space, I fold the distances between them in eleven-dimensional space. The amount of information is not reduced, it's just that the space they occupy is reduced in dimension."
Zhang Chengzhi gasped.
He whirled around, looking at the department head and judges below the stage: "Full marks! Give him full marks for this course!"
He turned back, his eyes burning with fervor as he looked at Lin Yu: "You organize the theoretical foundation of the core code! No need to write the experimental procedures, just put my name on it and get it published in Nature's main journal! No, this is enough to win the Turing Award!"
The entire freshman class erupted in uproar. A freshman's final project—an academician was practically begging him to publish it in a top-tier journal?
Gu Feiyu was completely devastated. His academic achievements, which he was so proud of, were trampled into nothingness in front of Lin Yu.
Lin Yu, however, reached out and unplugged the USB drive in full view of everyone, then stuffed it back into his pocket.
"Not publishing papers."
Lin Yu looked at the shocked Zhang Chengzhi and said, "Once the theory is made public, it can no longer be monopolized."
"What...what do you want to do?" Zhang Chengzhi was stunned.
Lin Yu put one hand in his pocket and walked off the stage.
"If this algorithm were sold to one of the major internet streaming media giants in China with high bandwidth costs, it would be worth at least nine figures."
Lin Yu didn't turn his head, his voice echoing in the defense hall.
"This weekend is the National College Student Challenge Cup. I'm going to use it to raise my first angel investment."
Computer Science Department, Jinghua University, Underground Computer Room No. 9.
The air was filled with a mixture of instant noodle smells and the smell of computer case cooling.
Lin Yu pushed open the door to the server room and walked straight to the workstation in the far corner. Xia Zijing followed behind, carrying a backpack and two cans of chilled Red Bull.
The workstation was piled high with empty soda cans. A slightly chubby guy wearing thick-rimmed glasses was frantically typing on the keyboard, which was filled with red error messages.
Wang Lei. A well-known programming fanatic among freshmen in the Computer Science Department, he almost never communicates with anyone except when writing code.
"The concurrent processing interface is not aligned, causing the thread to lock up."
Lin Yu stood behind him, one hand in his pocket, glanced at the screen, and said in a calm tone, "If you change the request queue in line eight to asynchronous call, the latency problem will be solved."
Wang Lei's fingers, which were typing on the keyboard, suddenly stopped.
He turned his head, looked at the stranger who had suddenly appeared, and frowned: "Who are you? Don't you know the rules? Don't look at other people's code."
"Lin Yu. Physics Department."
Lin Yu pulled a black USB drive from his pocket and tossed it next to Wang Lei's keyboard. "Looking for a laborer. Help me write an engineering package."
Upon hearing the words "Physics Department," Wang Lei became even more impatient.
"What are you physics students doing here? I don't have time to make those free-fall simulation programs for you guys. Leave me alone."
He turned his head, ready to continue working on his code.
Xia Zijin placed a can of Red Bull on the table and pulled the tab.
