Xueba: The Knowledge I Teach, The Crit Is Returned

The next day, Saturday.

Gu Bai didn't sleep in either. He even promised Professor Luo Shifei to participate in the "National Mathematical Modeling Competition for College Students". Gu Bai didn't care whether he received the "Thank you for your patronage" award, he just did his best and left the rest to the will of God.

After having breakfast in the cafeteria, Gu Bai came to Room 201, 3rd Floor, Graduate Student, School of Mathematics.

Pushed the door to enter, and no one was there.

The room is not big, there is no desk, and there is a blackboard in the center of the room.

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

The title is probably: [Three merchants each take one entourage across the river, and the boat can accommodate two people at a time. The followers made a secret agreement that on any bank of the river, once the number of followers outnumbered the merchants, they would kill and overtake the goods, and the plan to cross the river by boat was decided by the merchants. Q: 3 merchants safely crossing the river without being murdered by their followers? 】

em........

Glancing at the title, Gu Bai smiled, this should be the "businessman crossing the river problem" in the mathematical modeling?

Difficulty?

Almost nothing for the current Gu Bai.

As for building a mathematical model, it shouldn't be difficult.

Although he has never systematically studied mathematical modeling,... Gu Bai, who is at the level of Mathematics Lv4, can solve it as long as he is faced with mathematical problems.

Picking up Luo's chalk, Gu Bai slowly added under the blackboard: "If a multiple decision-making model is adopted, and each river crossing is a state-connected transition process, it can be represented by a three-dimensional vector (m, n, z)."

"The value range of m: {0,1,2,3};"

"The value range of n: {0,1,2,3};"

"Z is expressed as {1: means 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....."

".... and so on, if the value position of the merchant m, the value of the follower n is also a material, record the kth time to cross the river and finally get the state S(k+1)=SK+(-1)* dk..."

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

Sure enough, even if the math Lv4 self, even if there is no problem similar to mathematical modeling that the system crit returns, there is no problem that can't be done with a little effort.

This classic businessman crossing the river mathematical model 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 level, and he is not familiar with word documents or excle tables, let alone expressing these mathematical formulas in programming language.

Fortunately, Gu Bai has two other teammates.

"If I remember correctly, one is Xue Jiabao, a junior in the computer science department, and the other is Li Mengfan, a junior in the mathematics department."

"Senior Xue Jiabao should have no problem with this simple programming logic, right?"

Gu Bai thought to himself, Gu Bai is not worried about mathematics, the only thing he is worried about is whether the team can write these mathematical models with computer programming.

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

A senior with glasses and disheveled hair came over and was stunned when he saw Gu Bai, then smiled: "Are you the new teammate introduced by Professor Luo Shifei?"

"Hello, Gu Bai." Gu Bai smiled and said hello.

"Xue Jiabao." The man smiled, stretched out his hand and shook Gu Bai.

However, when I saw the mathematical models that had been written on the blackboard, I was stunned, then looked at Gu Bai and asked: "This.... This thing is written by you?"

"Oh, I just couldn't help but write something because my hands were itchy." Gu Bai laughed.

"Fuck you, you're awesome."

"This question, I studied it with Li Mengfan for a long time yesterday, you can solve it in a while?"

Xue Jiabao was a little unbelievable.

"Is it difficult?" Gu Bai was a little speechless, and he probably understood the mathematical strength of his teammates.

Forehead.....

This sentence suddenly made Xue Jiabao stunned. Isn't this thing difficult?

If there are only 3 merchants with 3 followers, it is really not difficult, and the final answer can be found with a little bit of digging with the head, but the difficulty is that if there are m merchants with n followers, the problem is completely different.

"Damn it, you...you're that freshman Gu Bai, right?" After taking another look at Gu Bai, Xue Jiabao suddenly patted his thigh with a look of excitement.

"If there is no duplicate name, it should be." Gu Bai smiled faintly.

"Xueba, it's a pleasure to meet you!!!" Saying that, Xue Jiabao once again held Gu Bai's hand and introduced himself again: "Xue Jiabao, a junior computer science major, is 178cm tall and weighs 108kg. I don't have a girlfriend yet, I like lol, Warcraft, I don't like sports, oh, and I am good at programming languages ​​such as JavaScript, php, c..."

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

This guy is a super straight guy.

After a while, another senior Li Mengfan also came, but fortunately, senior Li Mengfan is more normal, but his math ability is really average, or maybe the standard of Linhai University's mathematics department is just like that.

However, Gu Bai did not insist on anything. The three members of the National Mathematical Modeling Contest formed by Linhai University met for the first time.

As for whether it can get results, Gu Bai doesn't know, but...do his best.

Fortunately, the competition is more than September, and it is still several months away. During this time, Gu Bai can also teach senior Li Mengfan's mathematical modeling problems. As for computer programming, Gu Bai's hope is only on senior. On Xue Jiabao.

.........

As time passed, Gu Bai's days became regular.

In addition to the usual library brushing books and classes, live teaching at night, and now there is a daily training of a mathematical modeling team.

em........

Speaking of training, in fact, Gu Bai is speaking on stage, Li Mengfan is studying below, and Xue Jiabao is editing on the computer.

Today, May 1st.

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

Different from the last "Jiangnan Ten Schools Joint Exam", this time the mock exam was not large, it was just a joint exam for a dozen high schools within Yangcheng.

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

And... the difficulty of the test paper this time is not too difficult, it is similar to the college entrance examination, so this basically represents the final result of the college entrance examination.
