Xueba: The knowledge I taught will be returned by crit

The next day, Saturday.

Gu Bai did not sleep late, and actually agreed to Professor Luo Shifei to participate in the ‘National College Student Mathematical Modeling’ competition, Gu Bai did not care whether the ‘Thank you for your patronage’ award or not, he just did his best, and the rest was handed over to Providence.

After breakfast in the cafeteria, Gu Bai came to the 201st floor of the 3rd floor of the graduate student of the School of Mathematics.

Push the door in, and there is no one.

The room was small, empty and without a desk, and there was a blackboard erected in the center of the room.

A question was scribbled in chalk on the blackboard, and there were several mathematical formulas below.

The title is probably as follows: [Three merchants each bring a retinue across the river, and the boat accommodates 2 people at a time.] The entourage made a secret agreement that on either bank of the river, if there were more entourage than the merchants, they would kill people and cross the goods, and the plan for crossing the river by boat was decided by the merchants. Q: How safe did 3 businessmen cross the river without being murdered by their entourage? 】

em……..

Glancing at the topic, Gu Bai smiled, this should be the ‘merchant crossing the river problem’ of the golden code in mathematical modeling?

Do you want to say difficulty?

For the current Gu Bai almost nothing.

As for building mathematical models, it should not be difficult.

Although no systematic study of mathematical modeling but… Gu Bai of the mathematics Lv4 level can solve it easily as long as he is facing a mathematical problem.

Picking up the chalk of Diuro on the side, Gu Bai slowly added under the blackboard: “If you use the many-independent decision model, and set that each crossing of the river is a state-connected transfer process, it can be represented by a three-digit vector (m, n, z). ”

“where m takes the value range: {0,1,2,3};”

“Range of values of n: {0,1,2,3};”

“z denotes {1: denotes rowing to the other side of the river; 0 means rowing to this bank of the river; Then its state quantity is expressed as (1) when m=0 or 3, n={0,1,2,3}, when m=1 or 2, m=n…..”

“…. By analogy, if the value position of the merchant m and the value of the entourage n are also substance, the final state of the kth river crossing yields S(k+1)=SK+(-1)*dk…”

Looking at the model that had come out, Gu Bai smiled.

Sure enough, the mathematical Lv4 level self, even if there is no mathematical modeling similar topic returned by the system crit, as long as you push a little, there is no topic that cannot be done.

This classic mathematical model of a merchant crossing the river on the blackboard is 80% complete.

As for the next 20%, that is to use computer programming, but this step is no longer Gu Bai’s concern.

His computer level is still LV0, and he only masters word documents, even excle forms, let alone express these mathematical formulas in programming language.

But fortunately, Gu Bai still has two teammates.

“If memory serves, one is Xue Jiabao from the junior computer science department, and the other is Li Mengfan, a junior in the mathematics department.”

“This simple programming logic, Senior Xue Jiabao should have no problem, right?”

Gu Bai secretly thought that Gu Bai was not worried about mathematics, the only thing he was worried about was whether the team could write these mathematical models with computer programming.

After a while, the door of the room was pushed open again.

A senior wearing glasses and unkempt hair walked over, saw Gu Bai stunned, and then said with a smile: “You are the new teammate introduced by Professor Luo Shifei, right?” ”

“Hello, Gu Bai.” Gu Bai smiled and said hello.

“Xue Jiabao.” The man smiled and stretched out his hand to shake Gu Bai.

However, when he saw the mathematical model that had been written densely on the blackboard, he was stunned, and then looked at Gu Bai and asked: “This…. You wrote this stuff? ”

“Oh, I couldn’t help but write some just now with itchy hands.” Gu Bai said with a smile.

“Lying groove, awesome.”

“This question, yesterday I studied with Li Mengfan for half a day, you will solve it in this meeting?”

Xue Jiabao was a little incredulous.

“Is it hard?” Gu Bai was a little speechless, and he probably understood the mathematical strength level of his teammates in his heart.

Erm…..

This sentence suddenly made Xue Jiabao stunned, isn’t this thing difficult?

If it is just 3 businessmen with 3 entourage, it is really not difficult, and the final answer can be picked out with a little bit of the head, but the difficulty is that if m businessmen bring n entourage, the problem is completely different.

“I lean, you… You’re that freshman Gu Bai, right? After glancing at Gu Bai a few more times, Xue Jiabao suddenly slapped his thigh with a look of excitement.

“If there is no duplicate name, it should be.” Gu Bai smiled lightly.

“Xueba, luck will be lucky, !!!” Saying that, Xue Jiabao once again held Gu Bai’s hand, and then introduced himself again: “Xue Jiabao, junior computer department, height 178cm, weight 108 pounds, no girlfriend yet, like lol, Warcraft, don’t like sports, oh, and I’m good at JavaScript, PHP, C and other programming languages…”

Listening to Xue Jiabao’s self-introduction, Gu Bai touched his nose helplessly.

This guy, a proper super straight man.

After a while, another senior, Li Mengfan, also came, but fortunately, Senior Li Mengfan was more normal, but his mathematical ability was really average, or perhaps the level of mathematics students at Lin Hai University was like this.

However, Gu Bai did not force anything, and the 3 members of the National Mathematical Modeling Competition formed by Lin Hai University met for the first time.

As for whether he can achieve results, Gu Bai does not know, but: Do all in one’s power.

Fortunately, the competition is more than a few points in September, and there are still several months before now, during this time, Gu Bai can also teach Li Mengfan’s mathematical modeling problems, as for computer programming, Gu Bai’s hopes are only placed on senior Xue Jiabao.

………

Time passed day by day, and Gu Bai’s days became regular.

In addition to the usual library brushing books and classes, it is live teaching at night, and now there is another mathematical modeling team for the usual training.

em……..

Said to be training, in fact, that is, Gu Bai said on stage, Li Mengfan learned below, and Xue Jiabao edited on the computer.

This day, May 1st.

Yangcheng No. 1 Middle School ushered in their last mock exam before the college entrance examination.

Different from the previous ‘Jiangnan Ten Schools Joint Examination’, this mock exam is not large-scale, just a joint examination of more than a dozen high schools within Yangcheng.

But after all, it is the last mock exam for high school seniors, and all the school leaders of Yangcheng No. 1 Middle School still attach great importance to this.

And… This time, the difficulty of the test paper will not be too large, similar to the college entrance examination, so this basically represents the final score of the college entrance examination.
