The past two months have been a 'bleak period' for the Rubik's Cube computer and source code.

The publication of the paper on "effective and irrelevant carry screening", coupled with the lecture at Yanhua University, many people have a feeling that there will definitely be a lot of "free version" of the Rubik's Cube calculator on the market, and "effective and irrelevant carry screening" will also be quickly applied in many fields.

Two months later, there is still only a fragmented version of the 'Rubik's Cube Calculator' on the market, and there is still no breakthrough application in other fields for 'effective and irrelevant carry screening'.

Many in the industry came to their senses.

'Valid vs. irrelevant carry screening' is indeed a novel and very practical method, but in order to achieve applications in other fields, it is essential to have a sufficient understanding of it.

It's like some mathematical calculations, such as trigonometric functions, and you can't even figure out which angle corresponds to which side, and there will definitely be a lot of problems when you want to apply the calculation.

At this time, many people finally understood why Zhao Yi said that the proof of the 'Kakutani conjecture' was obtained in the process of studying the 'effective and irrelevant carry screening method', compared to the 'effective and irrelevant carry screening method', the proof process of the 'Kakutani conjecture' is just a bit of a brainstorm, most of it is the analysis of binary data graphs, and it only takes time for an undergraduate to study and figure it out.

'Valid vs. irrelevant carry screening' is completely different.

Liu Hemin is a top computer researcher in China, focusing on the research of artificial intelligence algorithms, and also guided Zhao Yi to write papers, and watched Zhao Yi's speech, and also came to Zheng Yang to communicate with Zhao Yi face-to-face, and then completely understood.

Other people want to read a lecture or a paper, and they need to fully understand it from beginning to end, but it takes a short time, and it is not easy to understand it and then apply it to other fields.

Actually, it's also normal.

The 'effective and irrelevant carry screening method' solves the problem of the Rubik's Cube algorithm that has plagued scientists for decades, and it must be quite difficult.

After two months, many teams that are conducting related research, or who want to use the 'effective and irrelevant carry screening method' to solve some data mining, screening and other problems, have fully understood, and the solution they have come up with is--

Buy the source code!

The core algorithm of the Rubik's Cube computer is the 'effective and irrelevant carry screening method', and there must be some related important algorithms, and the source code must be very valuable for research.

In addition, the source code itself is also very valuable, and if it can solve the calculation problem of the Rubik's Cube, it can further solve the fourth-order Rubik's Cube, and develop a variety of functions from it.

Only the latter point is valuable.

Many companies at home and abroad hope to contact and purchase the source code.

Zhang Zhen received quotations one after another, at first it was one million yuan, two hundred thousand dollars, and later it became five or six million yuan, and there was a foreign laboratory, which was quoted at one million dollars.

A million dollars!

Zhang Zhen couldn't help but tremble when he heard this, he is the manager of the interactive technology department of Zhouyu, and he is well-informed, but the development of domestic computers has just started, and it cannot be compared with other industries.

For example, the amount of a round of financing of Zhouyu Interactive is only 46 million yuan.

One million US dollars is equivalent to 8 million yuan, and such a large amount of transaction is really ......

"Zhao Yi, sell it or not!"

Zhang Zhen's voice on the phone was a little trembling.

Zhao Yi was also very excited when he heard it, and when he heard that it was a foreign research institution, he hesitated and asked, "Recently, how is the sales of the Rubik's Cube computer?"

"It's stopped abroad, but it's not bad at home!"

Zhang Zhen spoke.

The source code of the Rubik's Cube calculator has become popular, and the sales of the Rubik's Cube calculator have also reversed.

This may be related to the rumors that the Rubik's Cube calculator has stopped being sold abroad and will soon become 'out of print'.

'Out of print', it's always fascinating!

Although the Rubik's Cube calculator has various problems, such as the production is relatively simple, the function is relatively simple, but the 'out of print' is always different, it is not installed on the computer, and it is impossible to install it if you download the software later, because out of print does not mean that it is free.

That's why a lot of people download, buy, and install.

"Recently, it's about 10,000 or 20,000 a day, and it's estimated that it can last for a while, but I don't know ......."

"Then don't sell it yet!"

Zhao Yi still can't make up his mind, the main buyers are foreign laboratories, which sounds a little weird, "I'll think about it." ”

"Actually, it's okay not to sell it. ”

Zhang Zhen calmed down and suddenly said, "Don't talk about foreign countries, the domestic Internet industry is so big, and the future development must be tilted towards large companies, and now many companies want to buy, and whoever they sell to will offend other companies, and the follow-up is very troublesome, and you have to sign a lot of agreements to sell the source code, and it will be affected if you do something in the future." ”

"Okay, I'll think about it. ”

Zhao Yi touched his head with a headache.

In the past two days, Xu Chao simply lived in his house, and while studying the 'dynamic color discrimination' code written by Zhao Yi, he had not completely decided to do it together, and he also knew the confidentiality of the source code.

Zhao Yi still showed him the 'dynamic color discrimination' code.

This code is also thanks to Xu Chao, the copy of the 'dynamic color discrimination' execution program, the input and output information, is equivalent to giving most of the conditions.

And then.

He wrote the new code with ease.

Xu Chao was quite moved, he couldn't help it, 'dynamic color discrimination' is a laboratory thing, most of it is made by him, and it is not exactly his thing.

He's a lab worker.

At this time, Xu Chao turned around and asked, "What did you just say, eight million?"

Zhao Yi explained casually, "Just now, an institution wanted to buy the source code of the Rubik's Cube and bid eight million, but I refused." ”

"You want to buy my source code for this little money?"

"Thinking too much!"

He shook his head and walked to the bathroom, leaving Xu Chao with his mouth wide open in surprise, and kept muttering in his heart, "Eight million, eight million, eight million......"

The next day.

Zhao Yi also began to receive information.

Some people found his phone, penguin number, and email address, some still wanted to buy the source code, and some asked for other things.

For example, some university professors call and ask him if he can make detailed annotations to the content of the paper, on the one hand, it is convenient to understand, and on the other hand, they also want to use the content of the paper to explain the advanced algorithm to the students.

He was also contacted by three publishers to see if they were interested in writing a book on the subject.

Zhao Yi was moved.

A publishing house contacted him before to discuss the issue of publishing a book, but he directly refused.

Things are different now.

At that time, Zhao Yi still had to study hard, how could he have time to spend writing books? Now he has to study hard, but he has a personal hard worker--

Xu Chao!

"So, Brother Chao, are you interested in helping me write this book? ”

"I think it has great potential to annotate the steps with the core code of the Rubik's Cube calculator!"

"A publishing house said that as long as the writing is written, there will be two universities and a training institution, and they will definitely order it as a textbook, and it will definitely sell well abroad!"

On the way to see Xu Chao leave, Zhao Yi asked with sincerity on his face.

Xu Chao was stunned for a long time, "You brought me to start a business together, just let me help you write a book?"

"This is also entrepreneurship!"

Zhao Yi explained, "Think about it, I take the initiative, how can I sign ten points, earn five or ten yuan for a book, and sell 100,000 copies, which is 500,000 or 1 million." ”

"You can sell it at home, and you can sell it abroad!"

"We're out in both Chinese and English, and it's okay to write briefly in English, anyway, the copyright must be occupied. ”

This is the method that Zhao Yi thought of.

It's a bit of a pit to sell the source code directly, and you have to sign a lot of agreements, and you may also have trouble using the source code if you develop something in the future.

It's better not to sell.

'Effective vs. irrelevant carry screening', no matter how complicated it is, is just a method, and it is only a matter of time before other people fully understand it, just like a fruit company, they think that there are a lot of talents, as long as they are sure that the research direction is correct, sooner or later they will completely figure it out, and the source code just helps them understand faster.

In the explosive age of the Internet age, time is money, not just talk.

That's why so many companies buy source code.

Zhao Yi simply made the code public.

Anyway, the papers have already been written, the speeches have been made, and the source code is simply not sold, and it may be possible to make more money by finding someone to help write a book and sell it.

Selling code is just a transaction, and the income from selling books is endless!

For example, if a certain university orders his book as a textbook, won't it order it every year?

Zhao Yi continued, "Writing a book is starting a business, and the income is endless! The purpose of starting a business is not to make money, let's do research while writing a book, and we will give you a commission......

He gave a slap in the face.

"Fifty percent?" Xu Chao widened.

Zhao Yi took a deep breath, simply stopped, and pointed to the taxi on the side of the road, "Goodbye, go slowly, don't send it!"

Xu Chao smiled and nodded, "Okay, I'll think about it, and I'll give you an answer tomorrow and the day after tomorrow!"

......

Five points, no less.

On the way Xu Chao took the train, he carefully calculated the accounts, and the sales of professional books were not good, but the algorithm books involving 'monopoly technology' would definitely be robbed by the industry in the early stage.

Plus, there will definitely be some college ordering.

The largest group of buyers of this kind of books is universities and institutions, and universities and institutions will definitely buy some and put them in the library if they do not offer relevant courses or carefully study the content of the books.

Meantime.

Professional technical books are not afraid of piracy, because the buying group is fixed, and pirated copies used to be bought by ordinary people, and there was no way to sell them at all.

The sales volume of 100,000 copies that Zhao Yi said can be said to be the most basic, and the domestic and foreign markets are put together, and the sales volume will definitely not be less.

Then the commission of five points will not be less, and it may be higher than his current salary in one year.

Xu Chao was moved.

He is not only interested in 'writing and selling books', but also about real entrepreneurship.

Zhao Yi gave him a basic salary of 10,000 yuan, as well as five points of technical equity, and then converted the technical equity into actual equity when the company was really opened in the future.

Technology equity is the direct benefit of technology.

At present, they only have technology, and the company will not be the same when it opens to expand its operation, because it involves a certain amount of investment, and it will also bring investment and income in other aspects.

Five points of technical equity does not sound like much, but Zhao Yi has almost studied the core content, he is just 'selling coolies' to improve, which is similar to the work done in the laboratory.

"A dignified doctor, selling coolie ...... to a high school student"

Xu Chao felt very sad when he thought about it, but before the train arrived in the capital, he had already decided.

Resign!

Compared with the days when I worked hard in the laboratory, waited for the evaluation of the title for a long time, and didn't make much money, I still had a head start doing research with Zhao Yi.

That's the job he loves.

The essential......

There's still a lot of money!
