Son, how did you become the richest man in elementary school?

What should be depressed in my heart is still depressed.

Gu Xiu could tell that she was depressed, but he didn't say much. Although Zhou Ying had low self-esteem because of her family conditions.

But her heart is still strong.

The self-healing speed is very fast.

That was the case. When the two of them came to the computer room, Zhou Ying's expression had already recovered, at least she couldn't see any sadness.

Now it was close to the start time of the game, many students had already found their seats and sat down, and some instructors also came, explaining to their teams.

Zhong Zhenming also came, and came directly to Gu Xiu and the two, with a cheerful smile on his face, and explained to them:

"Have you had a good rest last night?"

"Don't be nervous, just treat it as an experience experience, don't put too much pressure on yourself."

"The two of you have fewer people, and the workload must be greater than that of other teams, so pay attention to the reasonable allocation of time."

"When choosing a topic, try to choose what you are sure of. Once you make a choice, you must be good at looking up information..."

After explaining some precautions and things that need attention, Zhong Zhenming left directly and continued to work on his own affairs.

After all, in this kind of competition, the instructor can't talk to guide or anything, let alone participate in it himself.

At eight o'clock, the bell rang on time.

All the students immediately operated the computers in front of them, started to log in to the competition website, and downloaded the test questions.

Although it is not a unified national competition this time, it is still in accordance with the standards of the national competition. There are three questions in total, namely A, B, and C, which are divided into undergraduate groups and specialist groups.

Among them, undergraduates can choose one of A and B.

The specialist group can choose one of B and C.

Each group needs to choose its own topic as the goal, and then complete the work within the next 72 hours.

The timing of the competition is really tight.

After all, reviewing questions, solving questions, discussing, modeling, programming, and dissertations all take time, and three days is a little too much for three people.

Therefore, everyone chooses to reduce the time for reviewing questions as much as possible, hoping to select the topic as soon as possible.

But soon, the faces of the participating teams in the computer room changed.

"This question... is this question too difficult?"

"It's over, how can these two questions be so perverted!"

"The previous competition questions were not so difficult. Why are we so unlucky this year?"

"It's over, it's over, I can't even read the title!"

"Question A, under the conditions of safe operation of the power system, pursue the minimum cost of power generation, including the busbar system... What the hell is this?"

"Problem B is not easy, the [-]D reconstruction of pipeline slices..."

"How to do?"

"..."

Countless students discussed it.

The entire computer room was full of noise at this moment. Looking up, I could see many students frowning, feeling as if a catastrophe was imminent.

It was really the first time I saw the title, I was disappointed.

Zhou Ying's face was also pale.

difficult!

too difficult!

Although there were also problems in previous years, this year's questions are a bit too rare, and the difficulty of both questions is very high.

The first question is related to physics, and the main research is electricity storage and stable maintenance of power stations.The second question is related to biological genes, mainly discussing biological slices.

For most of the students in the Department of Mathematics and Programming, this is simply the beginning of hell.

Of course, although both have relevant professional requirements, there are still some differences between the two, and the difficulty is naturally different.

"Choose B." Zhou Ying suggested:

"B's words seem to be more difficult, but the main core problem is still in mathematics. The gene slice is only dabbled in, and we should be able to find relevant information."

This was her first thought.

In fact, it is also the first thought of most people after seeing the title.

But Gu Xiu shook his head: "Choose A."

"A?" Zhou Ying was surprised.

Gu Xiu nodded: "If I remember correctly, the scoring is based on the choice of questions. You see, many people are choosing question B now. We can try question A. It is relatively easier to get a good ranking."

"But in order to get a good ranking, choose a more difficult and uncertain topic..."

"Will it be thankless?"

"This question is too difficult. It mainly involves electricity, and it still needs electricity storage and electricity transmission. These things are not easy."

"Even if it's the information to check, I'm afraid it's not that easy."

Zhou Ying said with some worry.

Gu Xiu shook his head: "It's not necessary at all, and, in fact, I am sure of the two questions, so there is no question of whether it is difficult or not."

what?

Zhou Ying froze for a moment, then looked at Gu Xiu with astonishment.

what did he say?

He said that he was sure of both questions?

Just kidding!

Even though she had seen Gu Xiu's strength before, when the situation came to an end, Zhou Ying inevitably still had some doubts.

After all, in the entire computer room, the [-] participating teams are all frowning, and no one like Gu Xiu is sure of it.

This……

Could it be that all the college students present are inferior to a primary school student?

"Gao Shan and the others seem to have chosen question A as well." At this moment, Gu Xiu suddenly spoke.

Zhou Ying took a subconscious look, only to find that Gao Shan, Li Niu, and Luo Hantao were sitting opposite them. At this time, Gao Shan and Li Niu were discussing, while Luo Hantao was beside them...

Paint your nails!

"Well, let's choose A!" Zhou Ying made a decision almost subconsciously.

The children of the poor are in charge early.

So she seldom argues with others, even if she is bullied by others, she has always been submissive, and the patience passes.

But that doesn't mean she has no temper.

Since you can't compare with others in terms of family background, then compare them in other aspects.

And learning is her forte!

Now that the topic has been chosen, the next step is to seriously analyze the topic...

Chapter 240 Is This a Team Member?Are you sure it's not the ancestor?

Zhou Ying is a person who devotes herself to studying and can guarantee 100% concentration. After making a decision at this moment, she immediately discarded the messy thoughts in her mind.

Start reviewing directly.

As for Gu Xiu, he didn't have too many thoughts. It's not that he loves learning so much, but that he hopes to solve it as soon as possible.

At the moment, it is better to understand the requirements of the topic before talking.

Current science and technology cannot effectively store electricity, so electricity production and consumption must be equal at any time, otherwise it will threaten the power security system.

Therefore, it is necessary to predict the future power load to arrange the start-stop plan of the generator set, and to pursue the minimum cost of power generation under the condition of satisfying the safe operation of the power system.

Question 3: There is a 4-bus system with two units, one load and three transmission lines. Given the four-hour load and system backup requirements, it is requested to calculate the optimal unit combination plan for four hours, which ultimately needs to include Total cost, status of each unit by hour...

Question [-]: On the basis of Question [-], consider the constraints of the physical characteristics of the generator set, the constraints of the stability range, output, operating time, minimum operating time, etc., and re-establish the optimal unit combination plan...

Both of them are looking at the question carefully.

But after getting serious about it, Zhou Ying had a better understanding of this question in her heart, and at the same time understood a general idea.

At least, understand the current problems.

"Optimized combination of units and optimized start-up and shutdown are to optimize the selection of units operating at each time period under the condition of constraints, and find out the best operation plan of the units, so as to achieve the minimum cost of starting point."

"But the unit combination is a multi-variable, nonlinear programming and dynamic programming, there are obvious deficiencies."

"Shall we try the simulated annealing algorithm?"

"No, this algorithm converges slowly." Gu Xiu shook his head.

"What about fuzzy optimization?"

"Fuzzy optimization belongs to functions and fuzzy inference rules, and it is difficult to determine."

"This...then what to do?"

Zhou Ying frowned, her brain was already running at high speed, and it was good to be able to think of these two ideas, but she didn't expect to be rejected as soon as she proposed it.

For a while, I felt like I didn't know how to start.

But Gu Xiu smiled: "This is simple, just like typing codes."

"what?"

But Gu Xiu said: "Matrix real number coding genetic algorithm!"

This……

Zhou Ying was stunned for a moment, then she suddenly reacted and gave Gu Xiu a thumbs up:

"Great!"

"It's nothing great or not, let's start directly, time waits for no one, and you have to start writing your thesis as soon as possible."

"Okay, don't worry about this, I will definitely not let you down!"

Gu Xiu nodded without any hesitation.

Let's do it!

……

And when Gu Xiu and Zhou Ying had already determined their goals and began to quickly advance the model.

The Gao Shan trio sitting opposite them are still in the discussion stage at the moment.

"Your algorithm is not good, it is too thankless."

"Then your tabu search algorithm is fine, this dependence on the initial solution is too strong, we will waste a lot of time on it."

"Why waste time, aren't you programming? Your programming is fine, and it can save a lot of boring calculations."

"you……"

There must be quarrels, after all, there is a big beauty sitting next to her, although this big beauty is basically a vase.

But everyone wants to behave in front of this beauty, and everyone wants the other party to obey their arrangements.

But that's what it brings.

Their group didn't finally come to a consensus until it was almost time for lunch.

"It has been delayed for too long. We have to start as soon as possible, otherwise we will not be able to make it in the next time."

"That's right, student Luo, can you help us cook?"

The two boys spoke.

"What?" Unexpectedly, Luo Hantao, who was always sitting next to her, applying lipstick, doing manicure, and playing with the mirror, frowned:
