Chapter 330

The award distribution rules of the National College Student Modeling Contest are:

All regional awards will be divided equally between A and B.

All the national award places are divided equally between the two questions A and B according to half of the places, and half of the places are allocated according to the proportion of the number of questions A and B.

No matter from the perspective of the regional awards or the allocation mechanism of the national awards, if you choose the question that fewer people choose among the two questions A and B, the chance of winning the award will increase to a certain extent.

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

Under normal circumstances, the selection of topics during the three-day competition takes almost a morning.

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

No one casually glances at the topic, and the specific modeling ideas all appear in their minds, except for Cheng Nuo, of course!

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

After just hesitating for a moment, Cheng Nuo chose the splicing and restoration of the b-question shredded paper that is estimated to be chosen by many people.

Each modeling problem contains 34 questions, and this piece of paper is no exception.

Problem 1: For a given shredder shredded paper from the same page of printed text documents only longitudinally cut, establish a shredded paper splicing recovery model and algorithm, and perform splicing and recovery for the fragmented data of one page of the Chinese and English documents given in Annex 1 and Annex 2. If the recovery process ......

Question 2: For the case that the shredder is both longitudinal and cross-cutting, please design the shredded paper splicing recovery model and algorithm, and perform the splicing and restoration of the fragment data of one page of the Chinese and English documents given in Annex 3 and Annex 4......

Problem 3: The fragmented data given above are all single-sided printed documents, and from the actual situation, there may also be the problem of shredded paper splicing and restoration of double-sided printed documents that need to be solved. Annex 5 gives fragmented data for a double-sided printed document in English in printed English. Try to design the corresponding shredded paper splicing restoration model and ......

To sum it up. In fact, the difficulty of the three questions is increasing in turn.

The first question is just for you to restore the shredded paper that was cut longitudinally on one side. The second question is to restore the shredded paper that has been cross-cut and longitudinally cut on one side. The third question is to discuss the double-sided, cross-cut and longitudinally cut pieces of paper at the same time.

Cheng Nuo's idea is not to build a model step by step according to the order of the questions, which would be boring and boring for him.

According to his philosophy, only one model is needed to solve three problems at the same time.

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

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

After speaking, Cheng Nuo turned around, shook the mouse, and clicked on the MATLAB software and an ATLAB software imread function at the same time to read the 24 pictures in Annex 5, and Cheng Nuo got a 24 grayscale matrix aki,j,k1,24,i1,n,j1,m.

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

The next step is to use the binary method to transform the grayscale matrix, and through calculation, the binary image x,y formula can be obtained:

x，y1，thgx

x，y0，thgx

......

Cheng Nuo maintained his high efficiency as always.

Formulas come at your fingertips as if they've been stored in your head for a long time.

Actually, modeling is not that complicated. As long as you have the right ideas in your head, coupled with a smart enough brain, it doesn't take much time to successfully build a mathematical model.

Here, Cheng Nuo was lying on the computer desk, calculating carefully and carefully, and over there, the two sisters, Liu Qing and Gu Feifei, could really be described as boring......

Originally, the two wanted to get together to help Cheng Nuo, but as soon as they saw the large string of formulas like ghost drawings on the paper, they stuck out their tongues and swallowed the words very self-consciously.

"Fei Fei, do you say that the great god can do it alone?" Liu Qing swept through the other teams in the computer room and found that the three of them were all together to discuss. And only on their side, Cheng Nuo was lying on the table alone, and the two of them were paddling here.

No, they're not even paddling. Others paddling is a symbolic performance, and the two of them really started eating melons here.

Gu Feifei replied, "It should be possible." Seeing that the great god is so confident, he should be confident. Besides, in the end, even if we don't win the prize, we have nothing to lose. ”

"Well, that's right. Let's continue to have snacks. ”

"Well, I also brought a few bottles of kidney treasure for the great god, and I will give it to him when I eat later. ”

After saying that, the two women, who had nothing to do, hugged the snacks again and nibbled on them.

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

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

"I'm okay with that. ”

"No comment. ”

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

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

Suddenly, when Qiu Qi's gaze fell on a corner of the computer room, his gaze stopped moving.

"Qiu Qi, Qiu Qi, what's wrong with you, why are you stunned, let's discuss this topic again!" one of his team members next to him called him.

Qiu Qi looked unmoved, raised his finger, and pointed in one direction, "Look over there." ”

The man followed Qiu Qi's line of sight, "Eh, isn't that the team of one man and two women just now?"

"yes, what are the two girls on that team doing?" said Cliff.

The man fixed his eyes and saw that in the field of vision, Cheng Nuo was sitting at the computer desk, bowing his head and writing and drawing, which was not surprising.

The point is that the two girls are sitting side by side with a pack of spicy strips in their arms.

On the stool in front of them, there was an iPad held up by a stand.

The two women stared intently at the ipad with relish.

With his 1.5 eyesight, if you are not mistaken, what is playing on the ipad is the TV series Fuyao that is now popular!

What are we doing?!Aren't we in a modeling competition?!

Qiu Qi and his teammate looked at each other, both of them looking confused!
