From University Lecturer to Chief Academician

Efficient and don't care carry arithmetic.

This algorithm is designed to solve the "number of God". Reverts get further away.

For example, there is a Rubik's Cube that requires eight steps to solve.

When doing the next step of the Rubik's Cube rotation, there are sixteen possible transformation methods. Calculate and evaluate the overall state of the Rubik's Cube, and analyze each of them. If it will make the Rubik's Cube become more chaotic, then give up this step. Twist to continue calculating other rotation schemes.

The reason why we calculate the steps of 'putting the Rubik's Cube into a more chaotic state' instead of calculating the steps of 'making the Rubik's Cube closer to restoration' is because the latter requires a huge amount of calculation, which is equivalent to directly solving the problem, which is not practical at all. .

That's why the name of the algorithm is "effective and irrelevant carry". Whether it is effective or not, it can be "calculated and evaluated" to enter the next step of calculation.

Use the algorithm to perform reverse calculation, that is, when using a restored Rubik's cube to make the "become more chaotic" state carry on, you can find out the "rubik's cube requires the most steps to restore" and the "most chaotic" state, naturally' God's number' was cracked.

Since the algorithm is designed 'to solve the number of God', it is of course suitable to be applied to the calculation of Rubik's Cube reduction.

As long as the algorithm is applied, the minimum steps of Rubik's cube restoration and the detailed rotation and twisting methods can be directly calculated. No matter it is third-order, fourth-order, fifth-order, or higher-order Rubik's cube can be restored, and the amount of calculation is compared with other methods. There has been an exponential decline.

For the third-order Rubik's Cube, when the most steps are required, an ordinary thousand-yuan mobile phone only takes one second to calculate it.

The fourth-order Rubik's Cube is about ten times more complicated, requiring a high-end computer for one second.

The fifth order is more than ten times more complicated than the fourth order.

"Can you make an app that calculates the Rubik's Cube?" Wang Hao thought carefully, "The third and fourth-order Rubik's Cube can realize instant calculation and restoration. Maybe there will be a market for this small function?"

Wang Hao thought about it all night, and felt that there is still a market for Rubik's Cube restoration. The most important thing is that there is no and impossible app with similar functions on the market, and it may be able to make a lot of money.

It is not required to make too much money. It is enough to have tens or millions of dollars. It is considered as selling a patent.

After completing the research so hard, it turns out that there is not even a patent, so I share the algorithm principle and let other technology companies use the improved technology. I feel that it is a loss...

"Yes! Just do it!"

After Wang Hao made his decision, he started to write the core code the next day, and he also studied it by the way, making APP, putting it on the shelf, charging and other issues, and then he felt a little headache.

These are not advanced knowledge, and there is no difficulty in understanding them, but the content involved is too much and too complicated.

It's a bit troublesome!

Seeing Wang Hao pressing his forehead hard, Zhang Zhiqiang asked, "What's wrong?"

Wang Hao raised his chin and pointed to the computer screen, "There is a new research, and I am writing the core code."

Zhang Zhiqiang asked suspiciously, "Aren't you writing a paper?"

"Writing a paper?" Wang Hao was a little confused.

"It's the most current research mentioned yesterday!" Zhang Zhiqiang reminded, "You have analyzed so much, summed it up, you can definitely write a paper, and it's no problem to submit to SCI."

"oh!"

Wang Hao suddenly realized, and then shook his head indifferently, "It's just an idea, and it can't solve the most current problems. It doesn't make much sense to write it out, and there is no time."

He really didn't think it was necessary.

An idea about the maximum flow, but it will definitely not solve the problem in the end, it just provides an idea to solve the problem...

has no meaning?

Even if you patiently make a summary and write an eye-catching paper, you still can't solve the problem, and it takes a lot of energy to just submit to SCI.

It's not that he doesn't like ordinary SCI papers, the main thing is that he is too busy.

"Task 1" has accumulated more than 300 points of inspiration for the D-level difficulty research on nonlinear partial differential equations. He has never had time to use or think about it. He is thinking about when he will be free and then summarize the paper. Write it down.

As for the "idea for solving the maximum flow problem", we can only queue up slowly and wait for the time to be "free again".

"..."

After Zhang Zhiqiang heard Wang Hao's words, he didn't know what to do for a while. Thinking about his own research that has never made a breakthrough, it is not easy to write an SCI article, but the other party... doesn't like it?

With a long sigh, he picked up a small tomato and threw it into his mouth with precision.

Matt, so sour!

Wang Hao continued to read the knowledge of APP making, and scratched his hair hard with some headaches, and suddenly thought of the bald head in his previous life... No way!

Absolutely not!

He quickly turned his head to look at Zhang Zhiqiang, and asked in a low voice, "Brother Zhang, are you interested in making money?"

Zhang Zhiqiang was stunned for a moment, and quickly moved a chair over, "You say this, and I'm refreshed. How do you make money?"

Wang Haodao, "Let me tell you my idea first, you can see if it is feasible, it is like this, I want to make a simple mobile APP, and the function it realizes is also very simple, that is, to restore the Rubik's Cube."

"Use a simple input method, such as taking a photo, to extract the state of the Rubik's Cube, and the APP can calculate the entire process of how to use the smallest steps to restore the Rubik's Cube."

"Uh-huh."

Zhang Zhiqiang nodded as he listened.

"Do you think there will be a market for this kind of app? I want to make a fee. I don't want to make too much money, just a few hundred thousand." Wang Hao asked. He is not an expert in making a fee app, and he can even be said to be a layman. , the opinion of others is also very important.

Zhang Zhiqiang moved the chair back, sat down calmly again, and said seriously after a long silence with no expression on his face, "Wang Hao, in fact, I also have an idea of ​​making money, and I also make an app. My app can realize the interconnection of people's hearts. "

"Just open the APP, no need for video, call, or typing, just click on a person in the communication list, your thoughts can be directly transmitted to the other person's mind in an instant, and the other person can also send you information through thinking. "

"How about it? Do you think there will be a market for this app? I don't ask for more money, just a few million..."

"What the hell am I..."

Wang Hao's face was so dark that he almost uttered dirty words. He found that Zhang Zhiqiang had the potential to be a joker, so he simply looked at Luo Dayong.

Substitution!

Wang Hao called Luo Dayong into the corridor, and said his thoughts seriously.

Luo Dayong also had the same doubts as Zhang Zhiqiang, "Are you sure you can realize this function?"

"My latest research."

"That will definitely make money!" Luo Dayong nodded affirmatively, "Don't say that there is no market, this function and this gimmick can attract many users to order and download."

"But, is it really possible?"

"I said yes."

"Sincere?"

"right!"

"Done!" Luo Dayong said earnestly, "Wang Hao, I believe in you. You can write the core code, but you need someone's help in making APP, launching it, and making money later, right?"

"If you have the core code to realize the function, you can find a template to nest it. Others are interface, icon, photo extraction and input. I know a little about OC, java and other programming languages, and I can be responsible for writing other codes. But a person I still can't do it, why don't I call Zhu Ping?"

"Zhu Ping has a very high level of drawing, and there is no problem in writing basic design codes, which can be of great help."

"sure."

Wang Hao said, "Then it's settled. Let's go to the teaching and research section of the Faculty of Science after get off work hours. There will be no one there for a long time. Let's discuss it together."
