Chapter 204

At 11 o'clock in the evening on the 22nd, Bi Qi and the others finally finished the first question of question A.

However, this is only a small step.

Question a, there are three questions in total.

The difficulty of the three questions gradually increases.

Now, they have just finished the first question.

There are two mountains behind waiting for them to climb.

For the first question, it took Bi Qi and the others fourteen hours to solve it.

Second question, according to Bi Qi's estimate, it may take at least twenty hours.

Bi Qi continued to ignore what was going on outside the window and worked hard.

Two o'clock in the morning on the 23rd.

Chen Liang yawned loudly, patted Bi Qi on the shoulder, and said sleepily, "Biqi, I can't hold it anymore, go back to bed first! Don't be too late, see you tomorrow morning.

"

Bi Qi nodded.

After a while, Fang Yunlong couldn't hold on anymore and staggered back to the dormitory to sleep.

Bitsy still persists.

Opening a bottle of Shenbao, Bi Qi drank it down in two or three gulps, threw the can into the trash can, his eyes were bright, and he continued to work energetically.

"...Next, calculate the electromagnetic wave moving distance, and the value obtained is...the earth's curvature factor! In this case, you can easily find the longitude and latitude of the transmitting point and the receiving point!"

"Yes, that's it. Haha, I am indeed a genius!"

Bi Qi's brain was in an extremely excited state, and coupled with the blessing of Shen Bao, he directly transformed into a njilang overnight, and his combat effectiveness was quite long-lasting.

So, when Chen Liang came to the computer room at around six o'clock in the morning on the 23rd, carrying soy milk and fried dough sticks, what he saw was Bi Qi with a pair of dark circles under his eyes, but his eyes were bright.

She looked like she was mumbling something.

"Biqi, you, you didn't sleep all night?" Chen Liang opened his mouth wide and asked in surprise.

"No, I am a cultivator, why should I sleep?" Bi Qi shook his head.

Chen Liang helplessly held his forehead, took out the fried dough sticks and soy milk from the bag and handed it to Bi Qi, "Hey, eat your breakfast quickly and go back to catch up on your sleep."

Bi Qi was eating fried dough sticks and drinking soy milk. He looked up at Chen Liang with bright eyes, "But I think I can still have liver! I want to be 007!"

Bi China has all the good employees!

"No, you don't want to!" Chen Liang still had a tough attitude and asked Bi Qi to go back and catch up on his sleep.

If he continues like this, Chen Liang is worried that Bi Qi will really shatter the void and become an immortal!

At that time, I didn’t get the award, but I also passed it on to a teammate, which was a huge loss!

Under Chen Liang's tough attitude, Bi Qi reluctantly stopped what she was doing and went back to her dormitory to catch up on her sleep.

And before leaving, he gave Chen Liang a task.

That is to make a program that can calculate the BP neural network algorithm.

After thinking all night last night, Bi Qi has found some clues to solve the second question of question a.

The second question is that Bi Qi needs to construct a sky wave transmission model.

Sky waves are radio waves that return to the ground after being reflected or refracted by the ionosphere in the air.

The BP neural network algorithm is a tool used by Bi Qi to construct a sky wave transmission model.

Chen Guangming nodded, accepted the task assigned by Bi Qi, then turned on the computer and began to enter the daily life of a programmer - typing code!

…………

Nine o'clock in the morning on the 23rd.

Exactly twenty-four hours have passed since the US Open started.

Different teams have different topics, different task arrangements, and different levels of members, resulting in vastly different progress.

The team that chose question A is now in mourning.

Originally, they thought that the difficulty of question A was probably the highest among the six questions, ranking in the middle.

However, after twenty-four hours passed, they no longer thought so.

I thought that for this question, I only needed to find the laws of physics and then I could work in an orderly manner.

But I never expected that this engineering question would turn out to be a big pit, trapping countless students in it and finding it difficult to climb out.

Marine electromagnetism is a specialized small subject. However, there is not much work in this field in China, and there are only a handful of established textbooks.

Most of the relevant literature is in English, and there are even a few in Japanese!

This is so fucking painful!

As for Japanese, most people have never studied it systematically. With many years of film reading experience, they only know a few specific Japanese words.

If you carefully check the information in this area, you will find that the earliest documents in the famous work can be traced back to 1951, and the formulas are like a sea, which is enough to make people's scalp numb and intimidating!

Students who are not majoring in mathematics spent this day almost with tears in their eyes while trying to understand the vast sea of ​​formulas.

Many students are even desperate.

Other questions, no matter how extreme, are just compilation of data.

But they chose question A very well, even the formula documents were compiled.

It simply doesn’t give people a way to survive.

Many teams that chose question A began to consider changing questions after a day of torture.

…………

10 a.m. on the 23rd.

After resting in the dormitory for more than three hours, Bi Qi appeared in the computer room in high spirits.

He first came behind Chen Liang and asked, "Have you finished the program of the bp neural network algorithm?"

Chen Liang raised a finger and said, "One minute, give me one more minute."

A minute later, Chen Liang sent the BP neural network algorithm program to Bi Qi.

Bi Qi moved his fingers and started modeling the second question of question a.

The transmission of sky waves is a quite complex process.

In addition, as stipulated in the question, the terrain for sky wave transmission is in hilly areas.

There are both mountains and rivers and trees.

Bi Qi's brain was running rapidly, while recalling the modeling techniques taught by Professor Gu Lu, he was perfecting the model bit by bit.

Bi Qi was completely focused, and all external disturbances were dismissed by Bi Qi.

He felt as if he had entered a mysterious and mysterious state.

My brain is clear and I don’t feel tired.

Bi Qi maintained this state for a full twenty hours.

At six o'clock in the morning on the 24th, Bi Qi sent the constructed model and data to Chen Liang and Fang Yunlong, and then he lay down on the table and fell asleep.

When Bi Qi woke up again, he glanced out the window drowsily and found that the sky had darkened.

He wiped the saliva from the corner of his mouth, raised his head and asked Chen Liang not far away, "What time is it now?"

Chen Liang answered while typing the code with his fingers, "It is now six o'clock in the afternoon on the 24th, and you have slept for a full twelve hours."

"How is your progress?" Bi Qi asked, rubbing his drowsy eyes.

"The first two questions are basically 90% completed! The third question has not started yet," Chen Liang replied.

"Then I'll ask the third question right away!" Bi Qi held on to the armrests of the chair and stood up, but sat down directly on the ground.

Chen Liang hurriedly helped Bi Qi up, "You haven't eaten for almost two days and your body is too weak. I bought the food a long time ago. You eat first and then continue after eating."

There are still more than twenty hours left before the modeling competition ends.
Chapter completed!
