Chapter 205

At seven o'clock in the evening of the 24th, Bi Qi officially began to overcome the third question of question A.

At ten o'clock in the evening, Biqi deduced the formula through the formula to determine the skywave scattering formula.

At one o'clock in the morning on the 25th, Biqi used the simulated fading algorithm to officially start building the model.

At five o'clock in the morning, the model was successfully built and the data began to be calculated.

At seven o'clock in the morning, through the data obtained by calculation, Bizzy determined the reflection of electromagnetic waves in the ionosphere.

At nine o'clock on the 25th, there were only twelve hours left before the end of the American race.

Biqi and their team, all three models of the three questions of question A have been built.

However, mathematical modeling does not mean that everything will be successful when the model is successfully built.

The final result is a complete paper in front of the judges, not a jumble of models and programs.

So the final burden was on Fang Yunlong, who was in charge of the thesis work.

He needed to present the model built by Bi Qi and the program programmed by Chen Liang in the form of a written paper in front of the judges.

And be as clear and concise as possible.

While being able to understand it yourself, it makes it easier for the judges and teachers to understand.

After all, there are more than 20,000 teams participating in the American competition this year.

The number of pages of the paper submitted by each team is generally twenty or thirty pages.

If you want to read a twenty or thirty page paper seriously, no half day is not enough.

But the judges didn't have time to spend half a day reviewing a modeling paper.

They pay attention to speed and efficiency, so at this time, of course, the more simple and easy to understand the paper, the more it will increase the favorability of the judges and teachers who review it.

At this time, Fang Yunlong also followed the progress of Bi Qi and Chen Liang to write papers.

By now, the entire paper has almost 70 percent complete.

Only the first abstract, the models and data for the third question, and the references and appendices at the end have not yet been obtained.

"I'll write the abstract, Chen Liang, you get the references and appendices. Yunlong, you only need to be responsible for the thesis part of the third question with peace of mind. Bizzie commanded as the captain.

Chen Liang and Fang Yunlong nodded in unison.

I participated in the American competition, so the modeling paper was naturally all in English.

Among the three, of course, Fang Yunlong has the best English, this is a super boss who has scored more than 690 points in the sixth-level test.

However, Bi Qi and Chen Liang's English proficiency is not bad.

Writing a simple summary is a good idea for Bizzie.

“Based on the properties of the ionosphere and some laws of physics， we

have established a complete mathematical model named MHPM that can well

simulate the refraction and reflection in the propagation of multi-hop high-

frequency radio waves......”

In ten minutes, Bizzie finished writing a short summary.

And Chen Liang, on his side, also finished the references and appendices.

The rest is only waiting for the part that Fang Yunlong is responsible for.

............

At five o'clock in the afternoon of the 25th, there were only four hours left before the deadline for the United States.

However, in the entire computer room, there is no team to submit a paper yet.

"How much is it missing?" Bi Qi asked Fang Yunlong as he forced himself to hold on to the sleepiness that came to his face.

Fang Yunlong's fingers kept tapping on the keyboard, wiping the fine sweat oozing from his forehead from time to time, "Come on, give me another half an hour." ”

Half an hour later, Fang Yunlong clicked Save, leaned back in his chair, and exhaled lightly.

"I've got it!" Fang Yunlong said with a bright smile.

When Bi Qi and Chen Liang heard this, they immediately came over.

Bi Qi took out his phone and looked at the time, "I don't have three and a half hours left, there is enough time, check it." ”

Bizzy split the paper into three parts, which the three of them examined separately.

One is to check for typos, and the other is to see if there are any arithmetic errors, or what are not perfect.

More than two hours have passed since this inspection.

The main reason is that Bi Qi felt that there was a place where the description was not clear enough, so Chen Liang wasted a lot of time by getting two pictures and inserting them.

At eight o'clock in the evening of the 25th, there was only one hour left before the end of the American competition.

"Is it okay?" Bizzy looked at his teammates.

"No problem!"

"I don't have that part either. ”

Chen Liang and Fang Yunlong replied successively.

Bizzie nodded and proceeded to the penultimate step of converting the paper to PDF format.

Finally, the paper will be uploaded in PDF format.

Seeing the words "upload successful" displayed on the computer screen, the three of them looked at each other and laughed happily.

"It's finally over!" Bizzie stretched widely.

"No, I'm sleepy, I haven't slept for more than 20 hours, and I'm floating when I walk now!" Chen Liang yawned.

"I went to sleep on the plane. I booked a ticket home at 11 o'clock tonight, and I'm going to leave quickly. Fang Yunlong waved his hand to Bi Qi and the others, "Two, see you in the next year!"

"Well, see you in a year!"

So far, it can be regarded as the end of the competition.

As for the release of the awards and results, it will be at least until the start of the new semester.

After eighty-four hours of ultra-high-intensity liver explosion, Bi Qi was also physically and mentally exhausted, and he and Chen Liang supported each other back to the dormitory.

Then he fell straight into bed and fell asleep.

............

This sleep, Bi Qi slept directly from the twenty-eighth of the lunar month to the twenty-ninth of the lunar month.

Bi Qi bought a ticket for the twenty-ninth night of the lunar month, so before going home, Bi Qi went to find Gu Lu.

Bi Qi went to Gu Lu's apartment.

Having said that, it's been a year and a half, and Bi Qi is the first time to come to Gu Lu's house.

Knock knock~~

Bizzy knocked on the door.

"Right now. ”

Gu Lu's voice came from the room, and a few seconds later, the door was opened, revealing Gu Lu standing at the door, wearing ordinary men's loungewear.

Seeing that it was Bi Qi, Gu Lu raised his eyebrows and said with a smile, "Come in." ”

Sitting on the sofa in the living room, Gu Lu poured Bi Qi a glass of water and asked, "Just woke up?"

Bi Qi nodded, "I'll come over after a meal when I wake up." ”

"When are you going home?"

"Tonight's plane. ”

"Bring me a good one for your father. ”

"Teacher, aren't you going back to Haicheng?"

"Not back. I'm alone, and it's the same for the New Year. ”

"Then why don't you ......" Bi Qi hesitated, looked at Gu Lu with a sincere look in his eyes, "I'm not going home, stay here with you!"

"Ahem, cough, cough......" Gu Lu coughed violently, "No, no, you better go home with your parents." ”

"Well, actually, I'm here today, and there's another thing?" Bi Qi rubbed his hands.

"What's the matter?"

"Didn't the Meisai just end yesterday, I don't know the bottom of my heart, so I want to ask the teacher about your ......"

Before Bi Qi finished speaking, Gu Lu understood what he meant.

Gu Lu got up and motioned for Bi Qi to follow, "Go to my study." ”

Bi Qi followed Gu Lu to the study.

Gu Lu turned on the computer and clicked on a file.

There are six folders in the file, which are marked with file names such as "Meisai A", "Meisai B", and "Meisai C".

"By the way, which question did you choose?" Gu Lu asked while controlling the mouse while turning his head to Bi Qi behind him.
