The military-industrial scientific research system of the academic master.

As the general manager of Torch Group, Chang Haonan is not only the financial sponsor of this conference and competition, but he is also well-known in numerical calculations and the entire field of mathematics.

Therefore, his decision to invite someone specially can indeed be used as a direct reason.

Moreover, the conference communiqué is only issued as a summary after all the agenda items have been completed.

Given Professor Harold Huang's level, even if he just reorganized the paper published in JCAS last year and gave a report, it would be enough to cause a big enough response at the conference.

Besides, although the other party has been silent for nearly a year, it is impossible for him to have completely stood still.

Even Chang Haonan was looking forward to whether the other party had any new results that had not been published during this period.

As far as he knew, Professor Huang's research direction did not seem to be very popular in the United States.

This meeting can also be a chance to strengthen our relationship.

When the conditions are ripe, we will consider digging it over.

Nowadays, there are many foreigners who come to China with unknown reputations to cheat people, but there are very few of them who have real talents and skills.

Torch Group can definitely set an example in this regard.

On the other side, Song Jingming quickly wrote down Chang Haonan's request in his notebook, and then stuffed everything in his hand back into his briefcase:

"Then Mr. Chang, I have nothing to do today. Just don't forget to set the questions. If there is an extra round of preliminary competition, we should add another round of question bank..."

"Don't worry about the questions."

Chang Haonan replied:

"I have already prepared the topic for the finals. As for the preliminary round... I think we can let the special guests of this conference, including myself, come up with a question each, and then randomly draw from them."

"fair enough……"

As the main person in charge of the entire conference including the competition, Song Jingming naturally knew that Chang Haonan was going to set a trap for COMSOL in the final.

But he didn't understand the technology and didn't know how Chang Haonan operated specifically, so he could only follow orders when it came to the questions.

……

After dealing with the matters at the Aviation Power Group, Chang Haonan finally got what he wanted and slipped away early.

But on the way, he asked Zhu Yadan to stop by the Torch Laboratory.

In fact, there was no such arrangement originally, but just now when Song Jingming was leaving, he suddenly mentioned the competition test questions to Chang Haonan.

After the latter finished giving the questions, he just put the floppy disk in the laboratory.

After thinking it over, he decided to just go and get it.

After all, according to the schedule, once the annual holiday is over, it is time to enter the preparation stage for the preliminary competition.

Therefore, the matter of setting questions really has to be done during the holidays.

Fortunately, for Chang Haonan, who is now experienced in battle, it is not difficult.

The finals questions are difficult to set because they require special design of subject areas related to the questions, and even some specific numerical values, so that the calculation process involves high calculation weight problems, which can trigger the BUG of the finite volume method.

You don’t have to consider these in the preliminary rounds.

Just pick two simpler projects from Liu Hongbo and abstract the problem a little bit.

About an hour later, two cars drove into the gate of the Torch Laboratory one after the other.

It was already the beginning of 2002, and the laboratory's new site outside the Fifth Ring Road had been fully completed and put into use.

Since the laboratory's testing center is a national basic science research platform, in addition to the teachers and students of Chang Haonan's research group, there are also many technical personnel from other units such as the Ministry of Science and Technology, Beijing Municipal Science and Technology Commission, and the Chinese Academy of Sciences working here.

Therefore, even though it was already the 29th day of the twelfth lunar month and Beijing University of Aeronautics and Astronautics had already started its winter vacation, there were still many people coming and going in the laboratory compound.

"Professor Chang, Happy New Year..."

"Mr. Chang, Happy New Year!"

"Teacher Chang..."

From the moment he got off the car, Chang Haonan received New Year greetings from almost everyone he met.

Although he could hardly recognize any of them, he at least nodded in response to their enthusiasm.

As he walked all the way into the main building, he even felt a little sweaty.

The Torch Laboratory implements a system of separate access to different areas, among which the above-ground part of the main building has the highest authority. Almost only people in his research group and a few people from the Torch Group and the Academy of Sciences can enter directly.

Everyone else needs to apply in advance.

Therefore, unlike the situation outside, this place seems deserted.

"I covered it so tightly, how come everyone can still recognize it..."

Chang Haonan took off his hat and scarf and complained helplessly.

Zhu Yadan, who had been following behind silently, showed an expression that he couldn't bear to look directly at it:

"I think it would be strange if they didn't recognize you, Commander..."

"And you've been wearing the same outfit since the beginning of winter this year... No, this includes every winter. Even if you're someone you don't know well, you should be able to remember them after seeing them a few times..."

"Uh……"

Chang Haonan stopped in his tracks and looked down at the hat and scarf in his hands.

Although I don't want to admit it, it seems to be the case.

If Zhu Yada hadn't mentioned it specifically, he wouldn't have even noticed it.

"Actually, I have many sets of the same clothes to wear in rotation, I don't always wear this one..."

"Of course I know."

Zhu Yadan replied:

"But I can't control what others think..."

This answer made Chang Haonan a little worried——

In other people's eyes, I wouldn't be the kind of sloppy person who doesn't change clothes for a month...

But soon, he suddenly thought of another more important thing:

"Speaking of which, if I wear the same clothes every day, will it affect your security work?"

"Like being able to be recognized from a distance or something like that."

In fact, Chang Haonan didn’t understand these things. He just watched some movies about assassination in his previous life, and similar things seemed to be mentioned in them.

"That won't happen. If it really had an impact, I should have reminded you a long time ago."

Zhu Yadan immediately shook his head:

"After all, you are in a generally safe big city, not on the front line, so the focus of security is still on your schedule and itinerary. As for when you get off the car... even if you change your clothes every day, it is easy for others to find your key target in the crowd just by looking at your position."

"Or in other words, if someone really pulls out a weapon at a dangerous distance, then the security work has already failed..."

After this explanation, Chang Haonan felt a little relieved.

If you think about it carefully, it makes sense. When I am speaking on stage or attending an event, even my name tag is written and placed in front of me, so I don’t need to rely on clothes to identify my identity.

Besides, there is no security guard who can really let someone set up a sniper within 200 meters, right?

No way?

……

While chatting with Zhu Yada, the two of them had already arrived at Chang Haonan's office and found the floppy disk box buried deep in the drawer.

In fact, early forms of USB flash drives have begun to appear on the market, but their application range is relatively small and their stability is still relatively poor, so they have not yet been fully promoted.

When storage pressure is not great, floppy disks still occupy a relatively mainstream market.

In fact, when Chang Haonan was just reborn, he thought about whether he should set up a company in advance to register the USB flash drive and then make a fortune from it.

However, before he had the chance to start doing this, he had already taken off within the Science and Technology Commission system.

In the next two years, he even became the chief planner of Aviation Power Group.

Considering that the USB interface flash drive patent ultimately belongs to a Chinese company, if it were to compete with its own people for it now, it would inevitably look ugly.

And there is also the suspicion of bullying others by taking advantage of power.

So, in the end, it was left unresolved.

"Professor Chang...?"

Just as Chang Haonan was reminiscing about the past while looking at a box of floppy disks, a familiar clear voice suddenly came from the door.

Chang Haonan, who was awakened, looked up and found that it was Yao Mengna standing outside.

"Teacher Yao?"

Chang Haonan looked at Yao Mengna, who was wearing a beige windbreaker and slim jeans, and was a little confused:

"Isn't it already vacation time...you didn't go home this year?"

"Well... the multiphase diagram segmentation algorithm project is about to be launched, so I'm busy in the lab for a few more days..."

Yao Mengna explained:

"I had originally bought a plane ticket to go home today, but... there was a sudden snowstorm over there, so all flights were cancelled, and I couldn't buy train tickets for the time being..."

At the end of the speech, there was a hint of grievance in the ending tone.

Zhu Yada, who was standing next to Chang Haonan, didn't even raise her head, but she could tell that the tone was at least 60% fake.

Even the fact that you can’t go home may not be a real emergency.

After all, people who really want to go home should check the weather forecast in advance. How could they find out that they can’t go back when the time comes?

If we further speculate from this, even if Chang Haonan didn't come to the Torch Laboratory today, he would probably receive a phone call from the other party complaining at the latest tomorrow...

But after thinking it over, she chose to keep her mouth shut.

Judging from past experience, no matter what happens next, it has nothing to do with security work...

And Chang Haonan...

Of course not as sharp as Zhu Yada.

Looking at the senior sister at the door, he said something as if possessed by ghosts:

"How about... come to my house tomorrow to celebrate the New Year?"
