Omnipotent Data

Chapter 332

When Cheng Nuo was about to upload his paper on CNKI, suddenly he stopped moving his mouse.

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

His modeling paper... is not perfect!

To be precise, the mathematical model he constructed on the "recovery of spliced ​​pieces of shredded paper" did not reach perfection.

Of course, the mathematical model that Cheng Nuo modeled is sufficient for solving the three problems given in the title, but it makes Cheng Nuo frown even more.

You know, the three questions in question b are all discussed when the shredded paper is cut horizontally and vertically.

It is...too idealistic!

As we all know, when a complete piece of paper is shredded, it is impossible to cut it in two ways: horizontal cutting and longitudinal cutting.

Nor will it be said that when criminals tear up paper that is enough to be used as physical evidence in court, they will tear it up in a straight direction with a ruler.

The tangential texture of the shredded paper must be very complex and diverse, not to say that there are few, but it is impossible to have a completely straight tangential texture.

Moreover, in reality, the shreds of paper that make up a piece of paper are not complete. Missing and damaged are common.

To put it simply, the situation given in the title is too ideal and absolute. It is a situation that is impossible in actual operation. Even if the problem is solved, it is almost impossible to recover the broken paper in the actual judicial evidence process. To any impetus.

If only to deal with this topic, Cheng Nuodake will submit the paper in front of him now.

I dare not say anything else. Cheng Nuo thinks it is safe to win a National One award.

But Cheng Nuo obviously wouldn't do that.

Because it makes no sense.

Cheng Nuo would not allow himself to submit the last unsatisfactory answer sheet.

Especially... if you have the ability to write satisfactory answers.

Cheng Nuo is not a hesitant person.

Although this might overthrow most of the work he had done in the previous eight hours, Cheng Nuo didn't feel any pity in his heart.

Mathematics work is like this, and no one can guarantee that his research direction will always be correct. Even Cheng Nuo could not guarantee it.

Look for a universal method to restore shredded paper.

This is what Cheng Nuo needs to do now.

The previous discussion only exists in cross-cutting and longitudinal cutting, and the shredded paper is not missing. It can only be discussed as a special case in a special case.

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

However, this time the algorithm will be more complicated and obscure.

As for the recovery method of shredded paper, Cheng Nuo intends to use the three methods of cross-section texture comparison, written font stitching, and information content boxing to reduce the error rate as much as possible.

Coupled with the consideration of missing and illegible handwriting, Cheng Nuo constructed another set of more complex algorithms to solve such problems.

Cheng Nuo lowered his head and meticulously listed the formula:

[……Construction matrix ai(m*n), ai(m*n)=[a11, a212……]

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

…………

The dusk gradually entered the night.

Ten p.m.

Seventy-two hours of games are often, in the blink of an eye, fourteen hours have passed.

Under the dim lights of the computer room, almost half of the people were lying on their desks and working.

In fact, it is not so easy to participate in the modeling competition. Except for a perverted guy like Cheng Nuo, normal students who want to complete a modeling paper in 72 hours will almost have to do a good job. ready.

For three full days, if you want to get a good result, 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 a string of codes 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 are also yawning again and again.

Liu Qing said while yawning, "The god, shall we go back first?"

"Well, go." Cheng Nuo smiled and nodded, "Yes, and also, you two won't use it tomorrow morning."

"Huh?!" Liu Qing was obviously taken aback, and said pitifully, "Great God, do you dislike our two troubles?"

"I didn't mean that." Cheng Nuo smiled bitterly and waved his hands again and again, "I mean, I can finish this modeling topic tonight, and I won't come tomorrow. And you two, naturally there is no need to come. ."

After listening to Cheng Nuo's explanation, Liu Qing opened her mouth slightly, her face flushed, "Great God, you are so fast!"

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

Man, how can you say fast!

He chuckled, "Not fast, more than ten hours, it's my normal level."

For more than ten hours, the man who drank the kidney treasure is so lasting!

"Great God, goodbye!"

"Goodbye!"

After sending away the two daughters of Liu Qing, Cheng Nuo turned the seat and continued to code.

Pop~~

唰唰唰~~

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

...

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

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

He glanced around subconsciously.

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

Qiu Qi's gaze saw Cheng Nuo who was still busy, and he whispered to himself, "This guy, although he is one and two, is he still very hardworking?"

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

after an hour……

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

This time he didn't hesitate to press the "OK" button.

Submitted successfully!

The version he submitted is naturally a revised version after one afternoon and one night, and a set of mathematical models that can solve almost all types of shredded paper recovery.

At this point, his journey in mathematical modeling has officially ended.

When he left, Cheng Nuo took a special look. In the computer room, there were two or three classmates who continued to explode, and there was a momentum for a decisive battle until dawn.

"Sure enough, young and hardworking!" Cheng Nuo sighed softly. UU reading www. uukanshu.com

Cheng Nuo, who did not need to continue to explode his liver, returned to the dormitory with ease, then climbed to the upper bunk and fell asleep.

…………

The next day, early morning.

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

Qiu Qi is no exception. He has only slept for more than three hours. After putting wind oil 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. Could it be that I stayed up too late yesterday." Qiu Qi thought in his heart, bowing his head and continuing to work on his own affairs.

When he raised his head again, it was already ten o'clock in the morning.

Looking in Cheng Nuo's direction again, Qiu Qi was full of doubts when he saw the empty seat.
