Chapter 330

The award allocation rules for the National College Student Modeling Competition are:

All competition areas awards are divided equally among questions A and B.

All the national prize quotas are distributed equally to the two questions A and B according to half of the quotas, and half of the quotas are distributed according to the number of questions A and B selected.

Whether from the competition area awards or the national award quota allocation mechanism, if you choose the question that fewer people choose among the two questions A and B, the chance of winning will increase to a certain extent.

Therefore, those teams that think they are not at their level or are hovering on the verge of winning should not only consider whether they are suitable for their group, but of course, they should also consider whether the competition for this topic is fierce.

Under normal circumstances, within three days of competition, it takes almost a morning to choose the question.

After all, the participating teams must have a full and comprehensive understanding of the two questions before they can make careful choices. Otherwise, when they are halfway through the question, they will find that it is not suitable for their group. Wouldn’t they have no place to cry?

No one glanced at the question a few times, and the specific modeling ideas all appeared in his mind, except for Cheng Nuo!

Others need a morning to choose the questions, but Cheng Nuo doesn't have to be so troublesome.

After hesitating for a moment, Cheng Nuo chose the B question that many people would probably choose - splicing and restoration of shredded paper.

Each modeling question contains 3 to 4 questions, and the splicing and restoration modeling of this piece of shredded paper is no exception.

Question 1: [For a shredder crushed paper (only cut vertically) given a paper shredder printed text file from the same page, a shredded paper splicing and restoration model and algorithm are established, and fragmented data of one page of the files given in Attachment 1 and 2 are spliced ​​and restored. If the restoration process...]

Question 2: [For the case where the shredder is both vertically and horizontally cut, please design a shredded piece splicing recovery model and algorithm, and splice and restore the fragment data of one page of the Chinese and English pages given in Attachment 3 and 4...]

Question 3: [The above-mentioned fragment data are all single-sided printed files. From the actual situation, there may also be a problem of shredded paper splicing and restoration of double-sided printed files that need to be solved. Attachment 5 gives the fragment data of a one-page English printed text double-sided printed file. Please try to design the corresponding shredded paper splicing and restoration model and...]

Let’s summarize. In fact, the difficulty of the three problems is incremental in sequence.

The first question is just to restore the shredded paper slices that are cut vertically on one side. The second question is to restore the shredded paper slices that are cut horizontally on one side and are cut horizontally on the same time. The third question is to discuss the shredded paper slices that are cut horizontally on both sides and are cut horizontally on the same time.

What Cheng Nuo thought about was not to build a model step by step in the order of the problem, which would be boring and boring for him.

According to his philosophy, to address these three questions, you only need to model one model to solve three problems at the same time.

In other words, as long as the built mathematical model can solve the third problem, the first two problems will naturally be solved.

After having an idea in his mind, Cheng Nuo turned his head and spoke to the two women behind him, "I'm going to start working, it's not time to eat, don't bother me!"

After saying that, Cheng Nuo turned around, shook his mouse, and clicked on the matlab software and a word document at the same time!

Modeling, programming, and papers should have been the work of three people, but now they are all on Cheng Nuo. This may be a difficult task for other modeling thighs, but it is much simpler for Cheng Nuo.

In three-in-one, the entire team is full of Cheng Nuo's voice, and there will be no conflict of ideas at all. Besides, no one said that the three tasks cannot be carried out at the same time, right?

Do it as soon as you say it!

Cheng Nuo chose to start with modeling, skip the current two questions, and directly model the third question.

First, the imread function of matlab software is called to read 24 pictures in Attachment 5. Cheng Nuo obtained a 24 grayscale matrix Ak(i,j), (k∈【1,24】, i∈【1,n】,j∈【1,m】).

Next, Cheng Nuo took out a stack of draft paper and excerpted the obtained grayscale matrix formula.

The next step is to transform the grayscale matrix using the binary method. Through calculation, the binarized image w(x,y) formula can be obtained:

w(x,y)=1,Th≤g(x)

w(x,y)=0,Th>g(x)

...

Cheng Nuo maintained his high efficiency as always.

Each formula is as easy as if it has been stored in my mind.

In fact, modeling is not very complicated. As long as you have the right ideas in your mind and a smart enough brain to successfully build a mathematical model, it won’t take much time.

On this side, Cheng Nuo lay on the computer desk and calculated carefully. On the other side, the two sisters Liu Qing and Gu Feifei can really be described as boring...

Originally, the two of them wanted to come up to help Cheng Nuo, but when they saw the large string of formulas on the paper that looked like ghost drawing talismans, they stuck out their tongues and swallowed the words with great self-knowledge.

"Fefei, do you think the master can do it alone?" Liu Qing swept through the other teams in the computer room and found that three people were gathering together to discuss and do it. On the other side, Cheng Nuo was lying on the table alone, and the two of them were paddling here.

No, they can’t even beat the water. Others’ paddlings are symbolic, and the two of them are really here to be the melon-eating crowd.

Gu Feifei replied, "It should be OK. It should be true. It's clear that the great god is so confident. Besides, even if we don't win the prize in the end, we won't lose much, right?"

"Well, that's right. Then let's continue to eat snacks."

"Yeah, I also brought a few bottles of kidney treasures to the master, and I will give them to him when I eat later."

After saying that, the two women who had nothing to do started to chew on the snacks again.

…………

"Huh, since that's the case, then we'll choose question B!"

"I have no objection."

"No objection."

It was ten o'clock in the morning. After two hours of discussion, a team in the computer room finally decided on the topic.

As a member of this team, Qiu Qi looked around the computer room for a week and wanted to observe the progress of other teams.

Suddenly, when Chiu Qi's eyes fell on a corner of the computer room, his sight no longer moved.

"Qiu Qi, Qiu Qi, what's wrong with you? Why are you stunned? Let's discuss this question quickly!" One of his team members next to him was calling him.

Qiu Qi looked unmoved, raised his finger and pointed in one direction, "Look at that."

The man looked along Chiu Qi's gaze, "Hey, isn't that the team of one man and two women just now?"

"Yes, then look at what the two girls in that team are doing?" Qiu Qi said.

The man looked at it and saw Cheng Nuo sitting at the computer desk, lowering his head to write and draw, which was nothing unexpected.

The key is that the two girls were sitting side by side with a pack of spicy strips each holding each other.

On the stool in front of them, there is an ipad that is standing up with a stand.

The two women stared at the iPad with relish.

With his 1.5 vision, if you read it correctly, the TV series that is now popular - Fuyao!

What is this doing?!Aren’t we modeling competitions?!

Qiu Qi and his teammate looked at each other, and they were all confused!
