Chapter 204

At eleven o'clock in the evening of the 22nd, the three of Biqi finally finished the first question of question A.

It's just a small step.

Question A, there are three questions in total.

The difficulty of the three questions is gradually increasing.

Now, they're just done with the first question.

There are two more mountains to climb behind.

The first question was, and it took them fourteen hours to get it done.

The second question, in Bizzie's estimate, I am afraid that it will take at least twenty hours.

Bi Qi continued to ignore what was going on outside the window and buried himself in hard work.

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

Chen Liang yawned heavily, patted Bi Qi's shoulder, and said with a sleepy face, "Bi Qi, I can't hold it anymore, go back to sleep first! Don't be too late, see you tomorrow morning." ”

Bizzie nodded.

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

Bizzy is still holding on.

Open a bottle of kidney treasure, Bi Qi drank it in two or three sips, threw the can into the trash, his eyes lit up, and he continued to work energetically.

“…… Next, calculate the distance traveled by the electromagnetic wave, and the resulting value is...... In this way, the latitude and longitude of the transmitting and receiving points can be easily obtained!"

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

Bi Qi's brain is in a state of extreme excitement, coupled with the blessing of the kidney treasure, it directly transforms into a night N Jiro, and his combat power is quite long-lasting.

So, when Chen Liang came to the computer room at six o'clock in the morning on the 23rd, he saw Bi Qi with a pair of dark circles under his eyes, but his eyes were shining, and he was writing formulas on scratch paper while babbling about something.

"Bi Qi, you, you haven't slept all night?" Chen Liang said in surprise as his mouth opened wide.

"No, I'm a person who wants to cultivate immortals, what kind of sleep do you sleep!" Bi Qi shook his head.

Chen Liang helplessly held his forehead, took out a copy of the fritters and soy milk in the bag and handed it to Bi Qi, "Oh, let's eat breakfast quickly, go back and make up for sleep after eating." ”

Bi Qi ate fritters and drank soy milk, looked up at Chen Liang, his eyes lit up, "But I think I can still have a liver! I think 007!"

Bi - China's good employees - Qi!

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

If he continued like this, Chen Liang was worried that Bi Qi would really shatter the void and become an immortal!

At that time, I didn't take the award, and I pasted a teammate into it, which was a blood loss!

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

And before leaving, he gave Chen Liang a task.

That is to get a program that can compute BP neural network algorithms.

After a night of thinking last night, Bizzie had found some eyebrows to solve the second question of question A.

Second, Bizzy needs to construct a transmission model of skywaves.

The so-called sky wave is a radio wave that returns to the ground after being reflected or refracted by the ionosphere in the air

The BP neural network algorithm is a tool for Biqi to construct a skywave transmission model.

Chen nodded and took 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.

Twenty-four hours have passed since the start of the competition.

Different teams have different progresses due to different topics, different task arrangement sequences, and different levels of members.

And the team that chose question A was full of mourning at this time.

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

Twenty-four hours later, though, they didn't think so at all.

I thought that this problem only needed to find the laws of physics to work in an orderly manner.

But I never expected that this engineering question was actually a big pit, trapping countless students in it but it was difficult to climb out.

Marine electromagnetism is a specialized small discipline, however, there is not a lot of work in this area in China, and there are only a handful of textbooks in shape.

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

This is a real pain!

As for Japanese, most people have not learned it systematically, and with many years of experience in reading films, they only know a few specific Japanese.

A careful inquiry of this information will reveal that the earliest documents in the famous work date back to 1951, and the formulas are like a sea of formulas, which is enough to make people's scalp tingle and daunting!

Non-math majors, this day, almost with tears in their eyes, while trying to understand the vast formula.

There are even quite a few students who are already desperate.

Other topics, even if they go too far, are just compiling data.

And they chose the A question well, and even the formula literature was compiled.

It's simply not a way to live.

After a day of torture, many teams who chose question A began to consider changing questions.

…………

At ten o'clock in the morning on the 23rd.

Bi Qi, who had rested in the dormitory for more than three hours, appeared in the computer room in good spirits.

He came behind Chen Liang first and asked, "Is the program of the BP neural network algorithm finished?"

Chen Liang held up a finger, "One minute, one more minute for me." ”

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

Bi Qi moved his fingers and began to model the second question of question A.

The transmission of skywaves is a rather complex process.

In addition, it is stipulated in the title that the terrain of the skywave transmission is in a hilly area.

There are mountains and rivers, as well as trees.

Bi Qi's brain was running rapidly, and while recalling the modeling skills taught by Gu Lu, he perfected the model little by little.

Bi Quanquan was engrossed, and all the disturbances of the outside world were eliminated by Bi Qi.

He felt as if he had entered a state of mystery.

The brain is clear and tireless.

In this state, Bi Qi maintained it for twenty hours.

At six o'clock in the morning of the 24th, after Bi Qi sent a copy of the built model and data to Chen Liang and Fang Yunlong, he slammed it and fell asleep directly on the table.

When Bi Qi woke up again, he looked out the window in a daze and found that it was already dark.

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

Chen Liang replied while crackling his fingers on the code, "It's six o'clock in the afternoon on the 24th, and you've slept for a full twelve hours." ”

"How's your progress?" asked Bizzie, rubbing his confused eyes.

"The first two questions are basically 90% done! The third question hasn't started yet," Chen Liang replied.

"Then I'll get the third question right away!" Bi Qi struggled to hold on to the armrest of the chair, but sat directly on the ground.

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

There are more than 20 hours left before the end of the modeling competition.

Bizzie felt like he was going to speed up!
