They were done using a Rubik's cube calculator, and a little too late.

After Professor Liu Hemin's team stood up, the number of God has been nailed to '20'. They just cover and complete the calculation, and they can only be reduced to a small news.

Of course.

The team's research has merit.

All possible states of the third-order Rubik's Cube are about 4.3×10 to the 19th power.

This number is scalp-numbing, each state only calculates simple addition, and the amount of calculation for full coverage is also an astronomical figure.

They use the mathematical technique of "group theory", through the symmetry of different faces of the Rubik's Cube, and then divide it in the form of sets, and finally divide the initial state into tens of billions of state combinations.

It's much easier with numbers.

After releasing the research report, Kent State University mathematician Murray Davidson, in an interview with the media, praised the Rubik's cube calculator, "It is more useful than we thought, and through continuous calculations, we are now very sure, Rubik's cube calculator results are accurate."

Davidson's statement played a decisive role.

Many people in the academic circle questioned the Rubik's cube calculator before, because there are countless possible situations, as long as the exact algorithm is not announced, the result of the Rubik's cube calculator may be inaccurate.

Now the doubts are gone.

Davidson also talked about the algorithm of the Rubik's cube calculator, "I heard some Chinese colleagues say that the maker of the Rubik's cube calculator, Zhao Yi, is writing a paper on the core algorithm and will publish it publicly. He is really a great person. Algorithmic genius, we're all looking forward to that."

"I believe his algorithm can solve many problems and be applied to many fields."

Davidson showed 'can't wait'.

Other members of the research team were interviewed and expressed the same meaning. They all looked forward to Zhao Yi's paper.

Zhao Yi was a little bored after reading the report.

Now what he hates to hear the most is that it has something to do with the word 'thesis', and it's nothing more than someone in the country urging him to 'hand in homework'.Abroad, is there anyone urging?

It made him feel like going to school, reading, relaxing, or doing something else was not doing his job.

do-of!

I just don't 'do my homework'!

Open the algorithm package sent by Zhang Zhen, take a few breaks to relax first, and don't work too easily without thinking.

Compared with publishing papers, he is more interested in the blank robot used in experiments.

Chapter 96 The Hardcore Hacker

Zhao Yi made four algorithm packages sent by Zhang Zhen in one go, and felt that his fingers were more tired than his brain. When he had a coffee break, he took the time to look at the algorithm packages sent by Professor Liu for help.

These algorithms were placed in the computer without even moving them. He wanted to take a look at them patiently, but he never took the time.

Plus, it's mostly hard to read.

Professor Liu's research on artificial neural networks has reached the world's top level. The algorithms he uses in his research are all related to the top research and will definitely involve some advanced mathematical methods.

As the leader of the research, the main job is to formulate the framework, and there is definitely no time to write detailed algorithms one by one. The algorithm packages are all written by the doctoral students led by Professor Liu.

These algorithm packages can be debugged and run, but because the data involved is too complicated, the calculation amount of the program operation is a big problem, the output data is not perfect, etc., so we can only continue to make modifications, and the modification is also very difficult .

The important reason why Professor Liu asked other people for help is that the doctoral student who wrote the algorithm package has graduated and will not continue to do research with Professor Liu.

This is normal.

Doctoral students are working on projects with their supervisors. Whether the project is completed or not has nothing to do with them. They are equivalent to working part-time in the company. If they do well, they may choose to stay, and if they do not do well, they will leave.

The "National Academy of Sciences" is not something that ordinary people can stay if they want to.

Zhao Yi looked very seriously, there is an algorithm package whose theme is related to data analysis and differentiation, that is, to judge what the main content of the picture is based on some specific data information.

It sounds simple, but it is not easy to do.

For example, the simplest is to distinguish between cats and dogs.

Cats and dogs have similar shapes, and their body composition is the same. With a single data, it is impossible to make a distinction.

When using data to analyze cats and dogs, it can be distinguished based on 'similarity', that is, 'how much similarity is the target to cats', 'how much similarity is the target to dogs', and then compare the two data to see which similarity Whichever is higher will be determined.

The premise of the above judgment is that the computer already has the characteristic data of cats and dogs.

This is the easiest.

For the algorithm package sent by Professor Liu, the content of data analysis is much more complicated.

Zhao Yi looked at it for a long time, and then simply went to the "mathematics reference book". His advanced mathematics knowledge is too lacking, and mathematics is the theoretical support of computers, and advanced algorithms need to use advanced mathematics. The two are closely related of.

……

Going to school the next day was easy.

As long as it is time to go to school, don't think about computer and algorithm problems, but focus on learning.

Zhao Yi enjoyed his time in high school very much. The reason why he felt relaxed was also related to his test scores. He got 660 points in the midterm exam. As long as he worked hard to get into Mizuki, there would be no problem.

In this way, I will have a bottom in my heart.

Before Zhao Yi was anxious about his studies, the main reason was that his grades were too poor, and the admission scores of Shuimu University were too high, which ordinary students would never even dare to think about. It's much smaller.

of course.

Pride is not okay.

Zhao Yi is still working very hard. His two scoring subjects are Chinese and comprehensive science. To be precise, they are Chinese, chemistry, biology and physics.

To put it bluntly, the subjects of comprehensive science and mathematics are almost the same as mathematics. They all have fixed answers. Some questions that they don’t know are equivalent to pulling points. In contrast, Chinese questions are more active, and some questions are deducted. There is no way to score. The questions with fixed answers require a lot of accumulation and memorization. The ability of the system cannot help improve memory.

This is a very helpless place.

For example, the dictation of ancient poems will become a deduction point every time.

Zhao Yi still spent most of his time on the three subjects of science and comprehensive science. With fixed answers and no need for a lot of memorization, the efficiency of improvement is obviously higher.

after school.

The students also talked about grades, college entrance examinations and the like.

While the students in the third year of high school feel the urgency of their grades, they also have to start thinking about the future.

Zhao Linlin gritted her teeth and said angrily, "Yesterday, when my aunt told me about the college entrance examination, she kept talking about being a teacher and being a teacher. It really pissed me off! I will definitely not take the normal university entrance exam!"

"Then what are you taking?" Zhao Yi asked.

"I didn't think about it, maybe I will study medicine?" Zhao Linlin said with interest, "In the future, I may be an attending doctor and perform operations on the operating table." She said with a smirk, "When you get sick in the future, I will treat you Knife..."

Zhao Yi trembled all over, and began to imagine in his mind that he was suffering from appendicitis or something, and Zhao Linlin was the chief surgeon to perform the operation, and the knife went down...

Cut to the left!

All the way down!

Zhao Yi took a deep breath, quickly shook his head and said, "If you apply for medical school, I suggest you study gynecology."

"Why?" Zhao Linlin was puzzled.

Zhao Yi said seriously, "Then I will never meet you when I go to see a doctor."

"Die-go!"

Zhao Linlin pouted dissatisfiedly and asked Lin Xiaoqing, "Xiaoqing, what about you?"

"Should be able to test for national defense, military or police-related schools!"

Lin Xiaoqing's goal is much clearer.

Zhao Yi couldn't help but take a deep look at her, there are not many people in high school who can decide to take the "advance approval" exam.

"why?"

Zhao Linlin was puzzled, "Is that kind of school tiring?"

"I have had a dream since I was a child." Lin Xiaoqing's opening words are so great that Zhao Yi, Zhao Linlin and even Sun Liang, who just walked over, have a feeling of awe, "When I grow up, I must be my father. Leader, superior!"

"..."

"..."

"..."

Collective shame.

Lin Xiaoqing curled her lips, "If I apply for a school that is 'approved in advance', I may be able to become a cadre in the future, and then be promoted. My dad probably won't be able to get promoted in this life, and I have a good chance."

The three nodded collectively.

Makes sense!

However, this dream sounds very weird.

"What about you? Zhao Yi." Zhao Linlin asked.

Several people looked over at the same time.

"Mizuki!" Zhao Yi finally said it confidently, "My goal is Shuimu University."

Because he got into the top ten in the city in the midterm exam, others thought that Zhao Yi was very promising to be admitted to Mizuki, and Mizuki and Shouda University were the dreams of most high school students. It was normal for Zhao Yi to say that he would take the Mizuki exam.

Lin Xiaoqing asked with interest, "What major do you want to study? Computer?"

"Absolutely no computer test!"

Zhao Yi is very sure, but when it comes to specific majors, in fact, he has not thought about it carefully, "It should be related to science, right? Mathematics, physics, etc..."

His tone was uncertain.

Zhao Yi once had the experience of going to university. He clearly knew that the most important thing to apply for a major is to be interested in the major. Otherwise, it is no different from going to high school or junior high school. They are all under the pressure of graduation pressure and employment pressure. '.

It's hard to say that you can learn well.

To really talk about hobbies, it is difficult for him to connect himself with science subjects such as mathematics and physics.

On the contrary, biology is very interesting.

Some time ago, he read biology books and chemistry books, and found that he was very interested in biology, and he could read it seriously without using learning coins. The content of biology is really fascinating, such as cells, the structure of the human body, and art General genetic structure, xy chromosome...

and many more.

Finally it was Sun Liang's turn, and he said in confusion, "Should be the same as Zhao Yi, majoring in science, I don't know, my only hobby is playing games, maybe I can learn computers?"

"Then what university are you planning to take?"

"Isn't it too early to say this now?" Sun Liang shook his head and said, "The college entrance examination is still more than half a year away."

"Makes sense."

Zhao Yi spoke in support of Sun Liang, "If you want to go to university, you should ask Gao Yuan to see what she is going to and which city she is going to. If you separate, when you go home later, you will find that she has become someone else's daughter." That's a sad thing, my friend." His mouth was sad, but his face was gloating.

"Makes sense!"

Sun Liang nodded approvingly.

Lin Xiaoqing looked at Zhao Yi with vivid eyes, she pouted for some reason, and hummed lightly at him in disdain.

Turn your head.

Unhappy written all over his face.

Zhao Yi looked at it a little inexplicably, and even more than ten years of memory could not help him understand the woman's heart.

What's going on here?

Why are you angry!

……

At night, after nine o'clock.

Students left the school one after another.

Zhao Yi followed the crowd out of the school gate. When he saw a Land Rover police car passing by, he immediately pedaled his bicycle vigorously, and his speed suddenly increased a lot.

Sun Liang complained and shouted from behind, "Zhao Yi, slow down, what are you doing so fast!"

"You-sister!"

Zhao Yi cursed depressedly, and the next moment he heard a shout, "Student Zhao Yi, wait a minute."

It's Lin Xudong.

Zhao Yi turned and rode over full of resentment.
