When Wang Xiaodong finished the last step, he opened the data package and looked at Lu Zhou, "The iterative calculation program is completed . The coordinates for the far and close side of the moon, the speed, and the direction of Chang'e 3 are calculated . I'll send it to your email?"
Lu Zhou, who was writing, did not even lift his head, "Just send it to my QQ . "
Wang Xiaodong, "Okay, what's next?"
"… The satellite orbit around the moon and the satellite landing trajectory geometry data and parameters are all here . You'll have to do the plotting," replied Lu Zhou . He threw the fully written A4 at Wang Xiaodong's desk and began his next calculation .
Wang Xiaodong looked at the data on the paper and noticed that he had changed the MATLAB software to a more professional SAS software for data mapping . Without any expression, he answered, "Okay . "
The two collaborated quietly and were fighting in their own areas of expertise .
It was around twelve o'clock when Lin Yuxiang walked quietly into the computer room . She placed a plastic bag containing two packs of yellow chicken rice and two cans of coffee on the table .
"Geniuses, time to eat!"
Wang Xiaodong got up and took his plate . With a smile on his face, he said, "Thank you . "
Naturally, Lin Yuxiang smiled back . She then walked next to Lu Zhou and said, "This one's yours . "
Lu Zhou did not raise his head as he replied, "Put it aside . I'll eat it after I finish calculating this . "
"Okay!"
It was nine o'clock at night when Lin Yuxiang yawned and went back to the dorm . Wang Xiaodong went back at around ten o'clock . As he was the main force for tomorrow, he had to get a good night's rest .
At this point, other than Lu Zhou, there were only a few people left in the computer room .
The genius mathematics student Luo Rundong was also there with Liu Rui .
There was also a third-year genius statistics student next to Liu Rui .
Their team configuration was special . The captain was responsible for programming and part of the modeling but did not do calculations . Most of the modeling was done by Liu Rui who then directed another person to do the thesis .
The third-year genius statistics student asked, "Is that guy in your dorm?"
Liu Rui nodded, "Yeah . "
The genius statistics student said casually, "That guy is insane . I briefly looked at him when I went to the bathroom . He chose question A . They'll have a lot fewer competitors than us . "
Liu Rui asked curiously, "Then why didn't we choose question A?"
Liu Rui has been solving question B for a while now and he did not feel like it was easy at all .
The genius statistic student said impolitely, "Because I have you guys for this year . Do you think I wanted to choose question B?"
Liu Rui: "…"
The other guy in his team: "…"
At three o'clock in the morning, only five people were left in the computer room .
At four o'clock in the morning, Lu Zhou was the only person still sitting in front of a computer .
By the time the sun started to shine through the window, Lu Zhou finally finished writing the last line of calculations .
When Wang Xiaodong opened the computer room door and walked in, he asked, "Finished?"
"Finished…" said Lu Zhou . He sighed in relief before saying, "The basic modeling is completed . The rest is programming, plotting, and sensitivity analysis by observing changes in the simulation . When you're done, I'll start writing the thesis . "
Wang Xiaodong nodded his head and said, "I got this . Go and rest . "
"Okay . "
Lu Zhou pinched his eyebrows, shook his head, and stood up before he walked out of the computer room .
Compared to his all-nighters during the summer, this was nothing .
Lu Zhou could not remember how he got back to the dorms . He just remembered that he opened the door and without even taking his clothes off, he went to sleep .
When he woke up, it was already dusk .
Lu Zhou sat up in bed and rubbed his messy hair as he took out his phone from his pocket to take a look at the time .
He recalled that he got back to the dorm around six in the morning .
"I slept for twelve hours…"
The next time he could sleep would be after the competition .
Lu Zhou went to the bathroom and cleaned himself up before heading towards the computer room .
When he arrived at the computer room, Wang Xiaodong was already writing the last line of the program .
Lin Yuxiang was away but she had brought food . The food was still hot . She probably left recently .
Lu Zhou opened the plastic bag and was about to grab a pair of chopsticks when he saw a piece of paper in the bag .
He slowly unfolded the paper .
[Try your best ~ ^ . ^ ~]
Lu Zhou: "…"
Lu Zhou crunched the paper and threw it in the rubbish bin before opening the disposable chopsticks to begin eating .
When he finished eating his dinner, he went to the bathroom and along the way, he threw the takeaway box away .
When he came back, Wang Xiaodong pushed his glasses . He stood up and started talking, "I've already finished writing the program . The code I've used for the three questions have been sent to your QQ . I'll come back at three in the morning . You'll have to do the thesis . "
"Ok, set an alarm . Don't forget . "
"I know," said Wang Xiaodong as he nodded his head and left .
Lu Zhou was the last relay runner . He sat in front of the computer and stretched .
It was seven o'clock at night and they still had 37 hours till the thesis submission time .
Within the next 37 hours, he had to summarize all of the calculation processes, modeling ideas, procedures, and answers to the three questions, all into a 20-30 page thesis .
No matter how exquisite the model or how ingenious the program, the judges would only judge by the thesis presentation . If the thesis could not be understood by the judges, then there was no hope for the prize .
Therefore, this last step could not be done sloppily!
Lu Zhou went into his working mode and he had completely forgotten about the time . His attention was entirely concentrated on the computer screen and his typing and thinking were operating at the speed of light .
The abstract and keywords had to be written in one page according to format requirements . Lu Zhou edited his abstract and even then, he barely made the cut .
No one knew his model thought process better than him . Therefore, this stage was easy to do .
The next was the cumbersome process of proof and reasoning . This was the main part of the entire thesis . Although it did not take up too much space, it was the most time-consuming part to complete .
The main reason was that not only did it involve mathematical modeling ideas, it also involved programming .
Lu Zhou was comfortable with mathematics but he needed to communicate with the coder for the program part .
Time slowly past by and the sun fell down and rose again . Once again, it shined across the horizon .
When the night was over, Lu Zhou had finished the last part of the question answering section .
He stretched and started at the thesis with his sleepy eyes before yawning as he started to talk to himself .
"… Next up is the reference and appendix . Finally, it's almost done . "
Lu Zhou placed his hands on the keyboard and he copied the title of the cited documents .
[
. . . Moon soft landing gravity turning track design and analysis (C), Huaguo Aerospace Association deep space exploration technology professional committee second academic conference . 2005 .
. . . Research on the detection and evasion scheme of manned lunar surface obstacles, Space Return and Remote Sensing . 2014, 35: 11-19
…
]
In total, he cited six Chinese theses, and one English thesis .
For the final step, Lu Zhou copied Wang Xiaodong's code into the appendix .
Wang Xiaodong stood behind Lu Zhou . As he pushed his glasses, he looked at the texts on the screen and asked, "Finished?"
"Yeah, all finished . Help me check for errors . If there are no errors, convert it to PDF format," said Lu Zhou while standing up from his chair . He shook his groggy brain and said, "I'm going to sleep . I'll delegate the md5 hash check and uploading work to you . "
"Go rest," said Wang Xiaodong . He paused for a second before saying with a concerned voice, "Be careful on the road . Don't trip . "
"Ok," said Lu Zhou as he nodded his head before he walked out of the computer room .
