Chapter 295 Am I a godfather?
Chang Haonan has been struggling for a while about what program to run on China’s first university-operated supercomputer.
What he is best at is of course programming to calculate numerical solutions to partial differential equations, which is also the essence of all numerical analysis and computational simulation processes.
But on the one hand, this kind of procedure is generally complicated. On the other hand, it is impossible for all those attending the ceremony to be industry insiders, and outsiders will certainly not be able to understand it, and they may not think that this kind of thing that will output a bunch of dry parameters in the end is very powerful.
So he finally decided to change his mind.
The most simple way is to run a helloworld.
This is the first demonstration program in the book “C Programming Language”, which is extremely classic and can be called the programming bible.
Affected by this, almost all programming teaching around the world will use the output helloworld as a starting point for students to get started.
Any programmer may not use C language, or may not like C language, but he has basically written a program with similar functions.
However, in 1997, computers had not yet become a required course for college students across the country, so basically only experts knew the ins and outs of it.
Even if this program is written in assembly language, it only takes about twenty lines, and high-level languages such as Java and Python (Note 1) can be completed in one line.
Succinct and powerful.
Experts will only smile knowingly when they know you are making fun of it, and will not dislike the simplicity of this program. However, although laymen do not understand, but just from the perspective of watching the fun, they will also feel that this is very consistent with China’s current development theme towards the world. .
very perfect.
Chang Haonan, who finalized the plan, quickly wrote a simple unveiling ceremony process based on his previous life experience and handed it to Tang Lintian—
Although Du Yishan has been dealing with Chang Haonan on this matter, if it really comes down to the administrative work of providing money and people, it is best to have Dean Tang handle it.
As for the details after the general framework is in place, Chang Haonan does not need to worry about it.
Although it is not yet possible for the school to assign him a secretary in a big way, there will always be someone responsible for these things.
According to the original plan, in the next three days, Chang Haonan only needs to prepare a slightly more formal suit (paid for by the school, of course), and then read the script of his speech on the day of the unveiling, so as not to get stuck on the spot or read the wrong words into the script. .
As for the rest of the time, I mainly work with Fang Zhen to optimize the design of the stratospheric airship that is being developed with Zhejiang University.
Of course, Chang Haonan no longer needs to do this kind of work himself. He only needs to give guidance on the key points of some algorithms.
Although it has only been a short year since they were reborn, many people’s abilities and destinies have already been changed by Chang Haonan.
Just like Fang Zhen, at this time last year he couldn’t even figure out the dipole grid analysis of a beam-type wing. But this year, although it seems that Chang Haonan and Yao Mengna are falling further and further behind, they have actually already fallen behind. He has become one of the top experts in aerodynamic analysis and optimization.
Otherwise, Zhejiang University would not have crossed half of China to find him as an airship.
This feeling, for a person like him who has experienced two lives, is simply not a good feeling.
At five o’clock that night.
“Brother, please be busy first, I’m going home.”
Chang Haonan looked at the wall clock on the wall and confirmed that it was time to get off work. He quickly closed the lid of his laptop, stood up, put on his clothes and prepared to leave.
Taking advantage of his free time these days, he had to experience what it was like to work a nine-to-five job that he had never experienced in his entire life.
“good…”
Fang Zhen just raised his head and said a word. Before he could say a few words, he heard a knock on the office door.
Then a timid voice sounded outside.
“Hello, is Teacher Chang Haonan here?”
This sentence stunned Fang Zhen, Chang Haonan and Xia Tian in the office.
Then they all looked at the door.
There were three people standing there, two men and one woman.
Judging from his age, he is similar to Chang Haonan and Xia Tian, but much younger than Fang Zhen.
They should all be students.
“I am Chang Haonan, but I am not a teacher yet.”
Although he was a little curious about the purpose of the visitor, he still put his clothes on the back of the seat again.
In any case, there is basically no hope of getting off work on time.
“You are looking for me…”
Perhaps it was Chang Haonan’s answer and his too young appearance that made the three visitors a little at a loss. After about ten seconds, the girl who first knocked on the door opened her mouth to explain again:
“Ah… we are students from the Department of Computer Science and Technology of Yenching University. We are here to ask you for advice on the universal application of differential evolution algorithm (DE) in constrained optimization problems. This is the responsibility of the three of us. Student ID card, and this, is the situation statement written by Teacher Yang Fuqing for us, stamped with the college seal…” The three of them took out a lot of documents and information at once.
He even caught a glimpse of two panda cigarettes, which were very popular in this era, in one of the people’s bags.
It is estimated that it was originally intended to be given as a gift to “Professor Chang Haonan”, but his real age is obviously slightly different from the expectations of the other three…
Chang Haonan didn’t care much about this. On the contrary, he didn’t know how to deal with it if the other party really wanted to show it, so he pretended not to see it and directly took the other party’s ID and the letter explaining the situation.
“Yan Da…”
It must be admitted that Beijing Airlines and Yanda are not schools at the same level.
The former is of course very important in the aviation industry system, but no matter which country it is in, industry and academia are two separate circles, and the former is generally at the lower end of the contempt chain.
So Chang Haonan was a little happy to meet three Yan university students who came here to ask for advice.
Because he suddenly had a bold idea.
Since the fate of many people and projects has been changed because of him.
What about schools?
Now there is only one year left until May 1998…
Who said that the C9 alliance cannot become the C10 alliance?
…
Of the three, the girl who keeps talking is called Lin Zhi, and the other two boys, one tall and one short, are a bit taciturn. The tall one is named Song Tingyu, and the one who is slightly shorter and fatter is called Jian Feiang, who looks a bit like Wu Yifan.
They came here because they wanted to participate in this year’s International Competition on Evolutionary Algorithms (ICEO) in Indianapolis.
Yang Fuqing, who wrote this note, should be an academician with qualifications close to that of Du Yishan, but neither she nor the three students specifically mentioned this, probably because they were afraid of being misunderstood as using their reputation as an academician to pressure others.
“This competition…if it were overseas, I would definitely not be able to attend…”
Although it was not stated explicitly in the letter, it can still be seen from the meaning between the lines that Yang Fuqing seemed to want to directly ask Chang Haonan to be their instructor.
Normally speaking, this kind of job of leading a team to compete abroad is definitely a good job. Not only can you go abroad for a tour at public expense, but if the students you lead get good grades, it will also be a huge bonus for the teacher.
But Chang Haonan’s situation is special after all. Whether it is from the perspective of confidentiality or safety, the organization will not let someone like him go abroad casually, and he himself is not worried about the situation on the other side of the ocean.
“Well… Teacher Yang said before coming here that if you have something to do and can’t leave, you can just use the name of your instructor.”
Judging from Lin Zhi’s reaction, Chang Haonan is 80% sure that this was her own temporary thought. However, in most cases, such competitions do only require the presence of instructors, but not all of them.
“Well, let’s talk about your specific problems.”
Chang Haonan has completely given up on the idea of going home from get off work.
“That’s right. In May last year, that is, before you published that paper, DE had already achieved good results in the first ICEO held in Nagoya. There were five test functions at that time, namely the ball model f (x)=∑(i=1.n)(xi-1)^2, xi∈[-5, 5], classical Griwank function (Note 2)…”
When talking about professional topics, the short Suga Feian changed his slightly dull look before and stepped forward to fluently introduce to Chang Haonan the situation of the first competition last year and the expected results of the second competition this year. Involved directions, etc.
In the three bags of information they brought, there was a box of floppy disks containing the complete algorithms submitted by all the contestants last year.
“Um…”
Chang Haonan inserted a floppy disk into the floppy drive.
While reading the tape, he casually asked the question he was curious about just now:
“Why do you think of coming to me? And the proposer of the DE algorithm should be at Berkeley. Are you so confident in defeating their local students?”
Two men and one woman looked at each other, with strange smiles on their faces.
“often…”
“Just call me Chang Gong or Dr. Chang.”
“Dr. Chang, although Professor Stern and Professor Price are indeed the fathers of the DE algorithm, after all, they are only preparing to determine the coefficients of the Chebyshev polynomial. It is you and Researcher Xu who really popularized this algorithm. , so now in the industry, especially in the circle where we are preparing to participate in the second ICEO, you are generally called the godfather and godmother of the DE algorithm…”
This answer almost made Chang Haonan stop.
Hey guys, have I become a godfather?
1: These languages are called high-level languages just by convention, and it does not mean that they are more powerful than assembly language and machine language.
As the saying goes:
Having studied real variable functions for ten times, I feel disheartened by functional analysis.
The random process passes randomly, and assembly language cannot compile it.
It can be seen that assembly language is still difficult to learn
