"This is an algorithm that I put together on the basis of a mathematical model, you can take a look."

In a café on Binjiang Road outside the South Campus of CUHK, Lin Meng looked at Lu Yi for a while, and then opened a document on his laptop and displayed the algorithm he had sorted out.

This is almost the source code, the ideas and conversion algorithms are included in it, and the only difference is the use of program programming.

Compression algorithm is an algorithm that narrows data storage and transmission through data encoding and storage rules.

For example, "hahahaha" 4 Chinese characters, in the computer storage and transmission needs to occupy 8 bytes, through the compression algorithm conversion encoding, can be stored as "haha4" for storage or transmission, this sub becomes 3 bytes of data.

When used or after the transfer is completed, the compression algorithm is used to reverse restore, and the data is restored to the original "hahahaha".

There are not many cores of the algorithm, more than 200 lines, and only more than 400 lines with annotations.

But Lin Meng is studying mathematics, and he needs to understand the coding rules and rules of information coding before he can sort out this algorithm, coupled with the logical verification and error detection of the algorithm, it can be seen how much effort Lin Meng has spent on this algorithm.

"What is the lossless compression ratio of this algorithm?"

Looking at the faint dark circles and bags under Lin Meng's face, Lu Yi did not point out this situation, but asked about some information about this algorithm.

In the description of the system, the compression algorithm created based on the advanced mathematical model can have a lossless compression ratio of up to 5%, which means that 100k data can be directly converted into 5k after compression, or lossless compression.

"If you do the math, it's about 7 percent."

Lin Meng shook his head regretfully and said, "I feel that I can further optimize it, but I can't find a clue in a short time, it seems that I haven't fully understood this mathematical model." ”

"It's already pretty good."

Lu Yi showed a hint of surprise on his face, and his psychological bottom line was to reach 10 percent, that is, 10 to 1.

After all, this is lossless compression, and it is destined to be impossible to achieve the compression ratio of tens of lossy compression.

"No, I'll study it again when I get back." Lin Meng flattened his mouth and was unwilling to give up.

At this time, the two waiters also brought a cup of coffee and a cup of milk tea that Lu Yi had just ordered, including some desserts.

"Let's eat something first, if you want to continue research, I'll use a USB flash drive to copy a copy of the mathematical model to you."

"Thank you Lu Yi."

Lin Meng picked up her cup of milk tea and took a sip of the straw, the mellow and sweet taste made her smile happily.

"By the way, have you found the person responsible for compiling the program?" After taking a sip of milk tea, Lin Meng asked with some curiosity.

"I found a female classmate in the class, who has a younger brother who is studying computer science on the East Campus."

Lu Yi stretched out his hand to put the dessert in front of Lin Meng, maybe it was the demon's brain that needed to consume a lot of blood sugar, or maybe it was the general nature of girls, after a few meals, Lu Yi had already seen Lin Meng's love for desserts.

"Female classmates?"

Lin Meng blinked, looked at Lu Yi and asked, "How is her brother's programming level?" ”

"I heard that it's very powerful, tomorrow he will come from the East Campus, and I will talk to him."

A trace of doubt flashed in Lu Yi's eyes, and he reached out and put a matcha cake in front of Lin Meng.

"Here, try this matcha cake, the matcha cake in this shop is very good."

"Uh-huh." Lin Meng nodded obediently, picked up the cake with a fork and tasted it.

"System, are you secretly deducting my points?"

Lu Yi watched Lin Meng finish eating a small piece of matcha cake, but he still didn't receive the prompt for the points to be credited, and immediately questioned the already inflationary system, suspecting that it was secretly deducting his points.

Please foodies eat delicious food but there is no satisfaction index? This simply doesn't make sense!

"The system will not arbitrarily deduct host points, please self-review your own behavior."

The skeptical system replied calmly, at this moment it was wondering if it was looking for the wrong host, IQ and thinking mode were not up to standard, and it was impossible to become a scientist, but I didn't think that even EQ seemed to be flawed.

"Lu Yi." After eating the cake, Lin Meng suddenly asked, "Will your classmate come out with her brother tomorrow?" ”

"Yes."

"Then call me when you go out tomorrow, I'm afraid that brother doesn't understand this algorithm."

After Lin Meng finished speaking, he picked up the milk tea and bit the straw and drank it, with no strange expression on his face.

......

At seven o'clock in the evening, Lin Meng was sent back to the downstairs of the dormitory, Lu Yi went back to the dormitory and put away the laptop, took out the plan that had been sorted out and analyzed in the past few days, and said to Brother Zao, who was reading a book: "Brother Zao, do you have any spare funds to lend me some?" ”

Brother Zao raised his head and asked curiously, "What's wrong?" How much? ”

"About 1 million." Lu Yi roughly estimated it and reported a number.

"1 million!"

Xu Jiajun, who was reading the novel next to him, subconsciously exclaimed, and walked over with a somewhat anxious expression and said, "Lu Lu, has something happened to you?" ”

"You're going to start a business?" Compared with Xu Jiajun's concern, Brother Zao was calmer and probably guessed Lu Yi's purpose.

Putting down the book, Brother Zao said with a serious face: "I can't take out 1 million for the time being, Lu Lu, you tell me about your project, if it's feasible, I'll give it to my father." ”

Lu Yi walked to the door and locked the dormitory door, and then took the sorted out and analyzed project plan to Brother Zao.

"This week, Lin Meng and I studied a mathematical model, which is very suitable for application to the compression algorithm, and the core of the algorithm has been sorted out, which can be compressed to 7% losslessly."

"Shhh...... Lossless compression to 7 percent! ”

Xu Jiajun next to him couldn't help but take a breath, and anyone who has a certain understanding of the Internet understands what this means.

"Compress and restore, data can be 100% lossless?"

Brother Zao roughly looked at the project plan and asked, this project plan only has the general information of the compression algorithm and the preliminary project development plan, and does not involve specific data.

"100 percent damageless." Lu Yi nodded.

"You're going against the sky."

Brother Zao closed the notebook with Lu Yi's preliminary project plan in his hand and said, "How about 10 million, 2 percent of the shares?" ”

The excellent business sense made Brother Zao see the potential value of this compression algorithm, and did not hesitate to give a valuation of 500 million yuan to invest.

The underlying technology is difficult to break through, but once it breaks through, it is destined to be unstoppable, and others will beg grandpa to sue grandma for door-to-door money.

For industries with huge bandwidth and traffic, such as live broadcast, short video, and video, this compression algorithm is a sword of Shang Fang, and whoever wants to live can live, and whoever wants to die.

"Ten million, 0.1 percent of the shares."

In business, when it comes to interests, Lu Yi did not have too many personal feelings, but increased the valuation by 20 times according to his actual plan.

This is still the current valuation, and if it really develops according to plan, then this valuation will be fine to increase by another 10 times.

"The valuation of 10 billion is too high, you must know that the algorithm cannot be patented, and once it is cracked, it is equivalent to losing all the chips."

The compression algorithm cannot be patented, and it can only rely on encryption to ensure that its own interests are not violated, but no matter how good the encryption is, it cannot resist the cracking and analysis of others.

Even cracking a compression algorithm is easier than cracking other algorithm programs, because comparing the data before and after compression, a lot of valuable information can be analyzed, and then targeted cracking.

"I don't plan to apply it in the network field, you said that it will be burned into the chip, the software and hardware will be combined to register a patent, and then applied to the field of communication, so will the value be increased geometrically?"

Lu Yi reached out and took out the phone and put it in front of Brother Zao.

"You mean?"

Brother Zao's face showed shock, and then he shook his head: "This is impossible, it can't be done, the 5G communication standard has already been determined, and the communication network has almost been fully upgraded."

We don't have the strength to change global standards, and we can't get operators to upgrade their networks before 5G starts to recoup their investment. ”

"I made an appointment with Yashan to meet tomorrow, and her brother was responsible for the compilation of the algorithm, and I asked her if she was interested in becoming the CEO."

"Yashan? Li Yashan? Brother Zao frowned and fell into deep thought.

As a qualified rich second generation, he has a concern for some special classes of students in his school, and he doesn't dare to say that the whole school knows them, but he still knows who these students are in the class, and Li Yashan is one of them.

"If you can make Li Yashan the CEO, it will be 0.1 percent, if not, then 1 percent, and the valuation will be increased to 1 billion as a prospective investment applied to the communications field."

Brother Zao thought for a while, and finally agreed to agree to the valuation of 10 billion.

It's really too tempting to have this idea, if Li Yashan joins, even if this idea is not realized, then with this partnership with Li Yashan, it will not be a loss in the end.

The most important thing is that Lu Yi's thoughts pointed him to a path, a road with the expectation of breaking away from his father's aftermath and the title of the rich second generation.
