Valid vs. irrelevant carry algorithms.

This algorithm is designed to crack the 'number of gods', and the principle of the algorithm is not difficult to understand, that is, in the fixed state of the Rubik's Cube, calculate and analyze whether each 'possible rotation in the next step' will make the state of the Rubik's Cube farther away from the restoration.

For example, there is a Rubik's Cube that needs to be restored in eight steps.

When doing the next step of the Rubik's cube rotation, there are 16 possible transformation methods, and the overall state of the Rubik's cube is used to calculate and evaluate, and for each of them is analyzed, if it will make the Rubik's cube 'more chaotic', then give up this step of twisting and continue to calculate the other rotation schemes.

The reason why we calculate the steps of 'making the Rubik's Cube more chaotic' instead of the steps of 'bringing the Rubik's Cube closer to reduction' is because the latter requires a huge amount of computation, 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 carrying', whether it is valid or not, it can be 'evaluated through calculation' to enter the next calculation.

Using the algorithm to perform reverse calculation, that is, when the Rubik's Cube is restored to the 'more chaotic' state to be carried forward, you can find out the state of 'the most restored steps of the Rubik's Cube' and 'the most chaotic', and naturally the 'number of gods' is cracked.

Since the algorithm is designed to 'crack the number of gods', it is of course very suitable to apply it to the calculation of the Rubik's cube reduction.

As long as the algorithm is applied, the minimum steps of the Rubik's cube restoration and the detailed rotation and twisting method can be directly calculated, whether it is the third-order, fourth-order, fifth-order, or higher-order Rubik's cube can be restored, and the amount of calculation has decreased exponentially compared with other methods.

In terms of the third-order Rubik's Cube, when it takes the most steps, an ordinary thousand-yuan mobile phone can be calculated in just one second.

The fourth-order Rubik's cube is about ten times more complicated, and it requires a level of one second higher than that of a computer.

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 about it carefully, "The third- and fourth-order Rubik's cubes can realize instantaneous calculation and restoration, and this small function may have a market?" ”

Wang Hao thought about it for a night and felt that there was still a market for the Rubik's Cube restoration, and the most important thing was that there was no and could not have an APP with similar functions on the market, and it might be able to make a wave of money.

Don't ask to make too much money, just a few dozen or millions is enough, and it is regarded as selling a patent.

After so hard work to complete the research, the result is not even a patent, so I share the principle of the algorithm and let other technology companies use the improvement technology, which feels very bad when I think about it......

"That's right! That's it! ”

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

This is not advanced knowledge, and there is no difficulty in understanding it, but there are too many and complex things involved.

It's a bit of a hassle!

Zhang Zhiqiang saw Wang Hao pressing his forehead hard, looking distressed, and asked, "What's wrong?" ”

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

Zhang Zhiqiang asked suspiciously, "Don't you write papers?" ”

"Writing essays?" Wang Hao was a little puzzled.

"It's the biggest stream of research I said yesterday!" Zhang Zhiqiang reminded, "You have analyzed so much and summarized them together, you can definitely write a paper, and it is no problem to submit a SCI." ”

"Oh!"

Wang Hao suddenly realized, and then shook his head indifferently, "It's just an idea, and it can't solve the problem of the biggest stream, and it doesn't make much sense to write it, and there is no time." ”

He did feel unnecessary.

An idea about the maximum stream, but certainly not in the end does not solve the problem, just provides an idea to solve the problem......

What's the point?

Even if you patiently summarize and write a dazzling paper, it still doesn't solve the problem, and it takes a lot of energy to just cast a SCI.

It's not that ordinary SCI papers can't be looked at, 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, and he has never had time to use or think about it, and is thinking about when he will be free to summarize and write the paper.

As for the 'maximum flow problem solving idea', we can only wait in line slowly and wait for the time to be 'free again'.

“……”

Zhang Zhiqiang listened to Wang Hao's words, and he didn't know what to do for a while, thinking that his research had not made a breakthrough, and it was not easy to write a SCI, but the other party was ...... Can't afford it?

He let out a long sigh, picked up a small tomato, and threw it into his mouth with precision.

Mader, so sour!

Wang Hao continued to read the knowledge of APP production, grabbed his hair with some headaches, and suddenly thought of the baldness 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 the chair over, "If you say this, I will have energy." How to make money? ”

Wang Hao said, "I'll tell you my thoughts first, you see if it's feasible, it's like this, I want to make a simple mobile phone APP, and the function is very simple, which is to restore the Rubik's Cube." ”

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

"Uh-huh."

Zhang Zhiqiang listened and nodded continuously.

"Do you think there will be a market for this kind of APP? I want to do a fee, don't ask to make too much, just hundreds of thousands. Wang Hao asked, he is not an expert in making a paid APP, and he can even be said to be a layman, and other people's opinions are also very important.

Zhang Zhiqiang moved the chair back, sat down indifferently, and was silent for a long time with a expressionless face, and said seriously, "Wang Hao, in fact, I also have an idea of making money, and I am also making an APP, which can realize the interconnection of people's hearts and minds." ”

"As long as you open the APP, you don't need video, no calls, no typing, click on a person in the communication list, your thoughts can be instantly transmitted directly to the other party's mind, and the other party can also send you information through thinking."

"How? Do you think there can be a market for this APP? I don't want to make more, I just need to make a few millions......"

"I'm ......"

Wang Hao's face was dark and he almost got dirty when he heard it, 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 to the corridor and said his thoughts very seriously.

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

"My latest research."

"That's sure to make money!" Luo Dayong nodded affirmatively, "Don't say that the market is not a market, this function and this gimmick can attract many users to order and download." ”

"Really, though?"

"I said yes."

"Really?"

"Yes!"

"It's done!" Luo Dayong said seriously, "Wang Hao, I believe you." You can write the core code, but you just need someone to help you in APP production, listing, and follow-up money, right? ”

"If you have the core code to implement the function, you can find a template to nest, and the rest is to do the interface, icons, take pictures and extract input, etc., I know some programming languages such as OC and java, and I can be responsible for writing other code. But one person still can't do it, why don't you call Zhu Ping? ”

"Zhu Ping's drawing level is very high, and there is no problem in writing basic design code, which can help a lot."

"Absolutely."

Wang Hao said, "Then it's decided." In this way, after the end of work, we will go to the teaching and research department of the Faculty of Science, and there will be no one there for a long time, so we can discuss it together. ”
