Chapter 332

Just as Cheng Nuo was about to upload and submit his paper on CNKI, he suddenly stopped moving his mouse.

Because, in that moment, he suddenly realized a problem.

This modeling paper of his ...... It's not perfect!

To be precise, it is his mathematical model of "shredded paper splicing and restoration" that has not reached the level of perfection.

Of course, the mathematical model modeled by Cheng Nuo is enough to solve the three problems given in the question, but this makes Cheng Nuo frown even more.

You must know that the three questions in question B are all discussed in the case of shredded paper being cut horizontally and vertically.

It's really ...... Too idealistic!

As we all know, when a whole piece of paper is shredded, it is impossible to shred it in two ways: crosswise and longitudinal.

Nor will it be said that when the criminals shred up enough paper to be used as physical evidence in court, they would take a ruler and tear it in a straight direction.

The tangential texture of the shredded paper is certainly very complex and diverse, not that there are very few, but there is simply no completely straight tangential texture.

And, in reality, the shredded pieces of paper that make up a piece of paper are not complete, and it is common for them to be missing or damaged.

To put it simply, the situation given in the title is too ideal and absolute, and it is a situation that is impossible to occur in actual operation, and even if the problem is solved, it will hardly play any role in promoting the recovery of shredded paper in the process of real judicial evidence.

If you just want to deal with this problem, this modeling competition, Cheng Nuo can submit the paper in front of him now.

Don't dare to say anything else, Cheng Nuo thinks that he is still safe and secure when he wins an award from one country.

But Cheng Nuo obviously wouldn't do that.

Because that would be pointless.

Cheng Nuoke will not allow himself to submit an unsatisfactory answer.

Especially...... On the premise that you have the ability to write a satisfactory answer.

Just do it when you think of it, Cheng Nuo is not a hesitant person.

Although this may overturn most of the work he did in the previous eight hours or so, Cheng Nuo did not have any regrets in his heart.

Mathematics is like this, and there is no guarantee that your research will always be in the right direction. Even Cheng Nuo can't guarantee it.

Looking for a general method of reducing shredded paper.

This is the work that Cheng Nuo needs to do at the moment.

The cases discussed before, which only exist in cross-cutting and longitudinal cuts, and where shredded pieces are not missing, can only be discussed as a special case within a special case.

First of all, the first step is to construct the algorithm.

It's just that this time the algorithm will be more complex and obscure.

As for the restoration method of shredded paper, Cheng Nuo plans to use the combination of three methods: facet texture comparison, written font stitching, and information content into the frame, so as to minimize the error rate as much as possible.

In addition, considering the absence and blurred handwriting, Cheng Nuo constructed another more complex algorithm to solve such problems.

Cheng Nuo lowered his head and meticulously listed the equations:

【...... Construction matrix Ai(m*n),Ai(m*n)=[a11,a212......]

Number of feature groups x1=4.25,x2=8.02,x3=4.20......】

............

Dusk is fading into night.

Ten o'clock in the evening.

Seventy-two hours of competition are often fourteen hours in the blink of an eye.

In the dim light of the computer room, almost half of the people were still working on their desks.

In fact, it is not so easy to participate in the modeling competition, except for a perverted guy like Cheng Nuo, normal students, if they want to complete a modeling paper in seventy-two hours, almost all of them must be ready to burst their livers.

For three whole days, if you want to get a good score, the real sleep time may not even be guaranteed for ten hours.

"It's so late, you two should go back first. Cheng Nuo typed down a string of code on the computer, looked up at the dark sky outside, and said to the two women behind him.

Until now, the two women standing behind Cheng Nuo have also yawned again and again.

Liu Qing yawned as he spoke, "Then the great god, let's go back first?"

"Well, go ahead. Cheng Nuo smiled and nodded, "By the way, besides, you two won't be using it tomorrow morning." ”

"Huh?!" Liu Qing was obviously stunned, and said pitifully, "Great God, do you dislike the trouble between the two of us?"

"That's not what I meant. Cheng Nuo smiled bitterly and waved his hand repeatedly, "I mean, I can finish this modeling problem tonight, and I won't come tomorrow." And the two of you, naturally there is no need to come. ”

After listening to Cheng Nuo's explanation, Liu Qing's mouth opened slightly, and there was a faint flush on his face, "Great God, you are so fast!"

Cheng Nuo always felt that Liu Qing's words were a little uncomfortable.

Man, how can you say fast!

He laughed and said, "It's not fast, more than ten hours, it's my normal level." ”

For more than ten hours, the man who drank the kidney treasure lasted so long!

"Goodbye, great god!"

"Goodbye!"

Seeing off Liu Qing's two daughters, Cheng Nuo turned the seat and continued to type the code.

Bang Bang Bang ~~

Boom~~

In the entire computer room, only the sound of fingers tapping on the keyboard and the sound of the pen tip rubbing against the paper remained.

......

Late at night, two o'clock in the morning.

Qiu Qi finally couldn't stand it anymore, stretched his waist, saved the things he had written, and put on his schoolbag to go back to the dormitory to squint for a while.

He subconsciously glanced around.

At this point in time, there are not many people who are already busy, only a few are scattered.

Qiu Qi's eyes saw the figure of Cheng Nuo, who was still busy, and muttered to himself, "This guy, although he is a belt two, is he still quite diligent?"

After chuckling, Qiu Qi packed up his things and left.

An hour later......

Cheng Nuo logged in to CNKI again and entered the modeling paper submission portal.

This time he didn't hesitate and pressed the "OK" button directly.

Submitted successfully!

The version he submitted, of course, was the one that had been revised in an afternoon and an evening, a set of mathematical models capable of solving almost any type of shredded paper recovery.

This marked the end of his journey in mathematical modeling.

When he left, Cheng Nuo took a special look, and in the computer room, there were still two or three classmates who continued to burst their livers, and there was a momentum of a decisive battle until dawn.

"Sure enough, he is young and hardworking!" Cheng Nuo sighed softly.

Cheng Nuo, who didn't need to continue to burst his liver, returned to the dormitory easily, then climbed to the top bunk and fell asleep.

............

The next day, early in the morning.

The modeling team members who didn't sleep enough walked into the computer room one after another in a daze.

Qiu Qi was no exception, he had only slept for more than three hours, and after smearing wind oil essence on his eyes and forcing himself to wake up, he subconsciously glanced in the direction of Cheng Nuo's seat.

"Huh? I haven't come yet, so I stayed up too late yesterday. Qiu Qi thought so in his heart, lowered his head and continued to busy his own business.

By the time he looked up again, it was ten o'clock in the morning.

Looking in the direction of Cheng Nuo again, seeing the empty seat, Qiu Qi was full of doubts.

This is...... What's the situation?
