As for what program to run on the first supercomputer operated by a university in Huaxia, Chang Haonan really struggled for a while.

What he is best at is of course programming the numerical solutions of partial differential equations, which is the essence of all numerical analysis and computational simulation processes.

But on the one hand, this kind of procedure is generally more complicated, and on the other hand, it is impossible for all the people attending the ceremony to be insiders, and the layman must not understand it, and may not think that this kind of thing will output a bunch of dry parameters in the end is very powerful.

So he eventually decided to think differently.

The road to simplicity and running a hello world is done.

This is the first demo program in the classic C Programming Language book, which is the programming bible.

Influenced by this, almost all the world's programming teachings will also use the output of hello world as a starting point for students to get started.

Any programmer may not use C or may not be interested in C, but he has basically written a program with similar functions.

However, in 97, computer science has not yet become a compulsory course for college students across the country, so basically only insiders know the ins and outs of this.

The program only takes about 20 lines to write in assembly language, and even more in high-level languages such as Java and Python (Note 1).

Concise and powerful.

Insiders know that you are playing a stalk, they will only smile, and will not dislike the simplicity of this program, while although laymen do not understand, but only from the perspective of watching the excitement, they will also feel that this is very suitable for the development theme of Huaxia now going to the world.

It was perfect.

Chang Haonan, who finalized the plan, quickly wrote a simple unveiling ceremony process based on the experience of his previous life and handed it to Tang Lintian-

Although Du Yishan has always been docking with Chang Haonan in this matter, if it really wants to implement the administrative work of paying for people, it is still necessary to get Dean Tang's side.

As for the details after having the general framework, there is no need for Chang Haonan to worry about it.

Although it is not possible for the school to give him a secretary with great fanfare at present, there will always be someone in charge of these things.

According to the original plan, in the next three days, Chang Haonan only needs to prepare a slightly more formal suit (of course, the school pays for it), and then read his speech on the day of the unveiling, and don't get stuck on the spot or make mistakes in the script.

As for the rest of the time, the main thing is to work with Fang Zhen to optimize the design of the stratospheric airship that was engaged in with Zhejiang University.

Of course, now this kind of work does not need Chang Haonan to get started in person, as long as he points out the key points of some algorithms.

Although it has only been a short year since he was reborn, many people's abilities and fates have been changed by Chang Haonan.

Just like Fang Zhen, at this time last year, he couldn't even figure out the analysis of the dipole grid method for a beam wing, and this year, although it seems that Chang Haonan and Yao Mengna are getting farther and farther away, he has actually become one of the best experts in aerodynamic analysis and optimization.

Otherwise, Zhejiang Provincial University would not have crossed half of China to find him as an airship.

This feeling is simply not too pleasant for a person like him who has experienced two lives.

Five o'clock that night.

"Senior brother, you are busy first, I'm going home."

Chang Haonan looked at the wall clock on the wall, and after confirming that it was time to get off work, he buckled the lid of his laptop at the speed of light, got up and put on his clothes and prepared to slip away.

Taking advantage of these few spare days, he has to feel what it's like to work from 9 to 5 that he has never experienced in his life.

"Good ......"

Fang Zhen just raised his head and said a word, and before he could say a few words, he heard a knock on the office door.

Then a somewhat timid voice sounded outside.

"Hello, is Mr. Chang Haonan here?"

One sentence made Fang Zhen, Chang Haonan and Xia Xia in the office stunned.

Then Qi Qi looked at the door.

There were three people, two men and one woman.

looks at the age similar to Chang Haonan and Summer, for example, Fang Zhen is much younger.

They should all be students.

"I'm Chang Haonan, but I'm not a teacher yet."

Although he was a little curious about the purpose of the visitor, he put his clothes back on the back of his seat.

In any case, getting off work on time is basically hopeless.

"...... you are looking for me"

Perhaps it was Chang Haonan's answer, as well as his somewhat too young face, that made the three visitors a little at a loss, and after about ten seconds, the girl who knocked on the door at the beginning spoke again to explain:

"Ah...... We are students of the Department of Computer Science and Technology of Yenching University, and we are here to ask you about the universal application of differential evolution algorithm (DE) in constrained optimization problems, which is our three student IDs, and this is the ...... that Yang Fuqing wrote to us, stamped with the college seal.

The three of them pulled out a large pile of documents and materials in one fell swoop.

He even caught a glimpse of two panda cigarettes, which were very popular in the era, in one of the men's bags.

It is estimated that he was originally intended to be given to "Professor Chang Haonan" as a gift, but his real age is obviously slightly different from the expectations of the other three......

Chang Haonan didn't care much about this, but he didn't know what to do with it when the other party really wanted to take it out, so he pretended not to see it, and directly took the other party's documents and the explanation of the situation.

"Yan Da's ......"

It must be admitted that compared with JA and Yan University, they are not schools at the same level.

The former is of course very important in the aviation industry system, but in any country, industry and academia are two separate circles, and the former is generally downstream in the chain of contempt.

So Chang Haonan was still a little happy to meet three Yan college students who came over to ask for advice.

Because he suddenly had a bold idea.

Since the fate of many people and projects has changed because of him.

And what about schools?

Now there is only one year left until May '98......

Who says the C9 alliance can't become the C10 league?

……

Among the three, the girl who has been talking is called Lin Zhi, and the other two are tall and short and a little taciturn, the tall one is called Song Tingyu, a little short and fat, and Wu Yifan is a little similar to Kan Feiang.

They came here to participate in the International Evolutionary Algorithm Competition (ICEO) in Indianapolis this year.

Yang Fuqing, who wrote this note, should be an academician with qualifications close to Du Yishan, but neither she nor the three students specifically mentioned this, probably because they were afraid of being misunderstood as an academician.

"This contest ...... If I were abroad, I wouldn't have been able to attend......"

Although it was not explicitly stated in the letter, it can still be seen from the meaning between the lines that Yang Fuqing seems to want to directly ask Chang Haonan to be their instructor.

Normally, this kind of work of leading a team to compete abroad is definitely a beautiful difference, and you can go abroad to play a lap at public expense, not to mention, if the students you bring out the results, it is also a huge plus for the teacher.

But Chang Haonan's situation is special after all, whether it is from the perspective of confidentiality or security, the organization will not let a person like him go abroad casually, and he himself is not worried about the situation on the other side of the ocean.

"Is this...... Before I came, Mr. Yang said that if you can't leave if you have something to do, you can just hang the name of the instructor. ”

Judging from Lin Zhi's reaction, Chang Haonan can be sure that this is her own temporary idea, but in most cases, this kind of competition does only require the presence of instructors, but does not require all of them to be present.

"Okay, let's talk about your specific problems."

Chang Haonan has completely given up the idea of going home from work.

"In May last year, before you published your paper, DE had already achieved good results in the first ICEO in Nagoya, and there were five test functions at that time, namely the spherical model f(x)=∑(i=)(xi-1)^2,xi∈[-5,5], the classical Griwanck function (Note 2), and ......."

When it comes to professional topics, the short Kan Feiang changed his previous slightly wooden appearance, and stepped forward to fluently introduce Chang Haonan to the situation of the first competition last year, as well as the direction that the second competition this year is expected to involve.

Among the three schoolbags they brought was a box of floppy disks, which contained the complete algorithms submitted by all the contestants last year.

"Hmmm......"

Chang Haonan stuffed a floppy disk into the floppy drive.

Taking advantage of the time to read the plate, he casually asked the question that he was a little curious about just now:

"Why did you think of coming to me? And the proposer of the DE algorithm should be in Berkeley, right, are you so confident that you can beat their native students? ”

The three of them, a man and a woman, glanced at each other, and a somewhat strange smile appeared on their faces.

"Constant ......"

"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 going to be used to determine the coefficients of the Chebyshev polynomial, and it is you and Researcher Xu who really popularize this algorithm......

This answer made Chang Haonan almost untenable.

Good guys, I'm a godfather?

1: Just because these languages are called high-level languages is conventional, it doesn't mean that they're better than assembly language and machine language.

As the so-called:

The real variable function has been studied ten times, and the functional analysis is cold.

The random process is random, and the assembly language is not programmed.

It can be seen that assembly language is still difficult to learn
