I really don't want to lie down and win

In order to fool Yang Jian's son-in-law, the principal deliberately made a fake brand for Xu Mang, so that he can maintain the database with peace of mind, don't have any dissatisfaction with the reality, and be full of hope.

The depth of the routine is simply outrageous.

Bang bang bang!

After saying please come in, Xu Mang pushed the door open and entered.

"You are?" A middle-aged man looked at Xu Mang curiously.

"I'm the honorary deputy director of the Institute of Materials Science and Computer Science, and my surname is Xu." Xu Mang said solemnly, "I'm here to ask whether the material science database and intelligent synthesis software developed by Fuda have met your expectations , is there any need for improvement?"

"???"

what?

Institute of Materials Science and Computer Science?

By the way, is there such a department?

The middle-aged man looked at Xu Mang with a confused face. He was not very old, and he exuded a smell of salted fish all over his body, especially his eyes...Pull it off and press it directly on the dead fish ,There is no sense of violation and.

"you..."

"What are you really the honorary deputy director of the Institute of Materials Science and Computer Science?" the middle-aged man asked.

"..."

"Really!" Xu Mang hurriedly took out the certificate given by the principal of Fuda University, handed it to the middle-aged man, and said, "This is my certificate, please have a look."

After getting the certificate, the middle-aged man almost died of anger.

good guy...

Is it so rough?

Liars these days dare to lie to the deputy director of the Materials Department of Tsinghua University?

He is insulting my IQ!

however,

The deputy director of the Materials Department of Tsinghua University was also a boring person. Instead of calling the security guard immediately, he played a game of cat and tiger with Xu Mang.

When the boring Deputy Director of the Materials Department of Tsinghua University meets the even more boring Xu Mang, they are destined to collide with fiery sparks.

"Deputy Institute Xu, the database and software are used very well, but... I want to make some comments." The deputy director said: "I hope the database can be more advanced, because a lot of data is garbage data and has no value at all. "

"If these data are still stored in the database, it will only take up a lot of space and waste limited resources." The deputy director said: "Deputy Institute Xu, can this problem be improved, and I want you to give me an answer in person, a Answers that solve the problem."

I go!

This...

This is quite difficult!

Xu Mang thought about it, and soon he found a very perfect solution, adding a brand new algorithm to solve this problem.

however,

How does this algorithm calculate?

"Sorry...let me think about it." Xu Mang said awkwardly but politely.

"it is good!"

"I can wait for you!" the deputy director said solemnly.

It really is a liar!

Seeing Xu Mang frowning with a cute look on his face, the deputy director directly labeled Xu Mang a liar.

no nonsense,

Call security!

The deputy director silently pressed an emergency button on the landline. As long as the button is pressed, the school security department will respond quickly and arrive at the scene of the incident within 3 minutes.

This button is set in response to emergencies. In order to protect the lives of important scientific researchers, Tsinghua University has spent huge sums of money to build this rapid response system with a professional security team.

After 30 seconds,

Xu Mang said seriously: "Deputy Director, after my thinking, I can give you an answer. I will add a data weighting algorithm to the database in the future. The calculation process is like this."

"The attenuation of the weight value usage reading volume, according to the daily operations of different users, to calculate the proportion of a certain data."

"Usage refers to the amount of data used, read amount refers to the amount of data that users have read, and attenuation refers to the amount of data that has not been used or read for a long time." Xu Mang paused, and continued: " According to the three conditions, the final value of the data is calculated, and then compared with the same kind, the data with the highest value is presented to the user."

"Of course!"

"Deeper optimization can also be carried out, and the characteristics of the user can be calculated based on the ID of each computer and the ID of the software."

"For example... a certain student is researching nanomaterials, and the database background will perform special optimization processing on the data of nanomaterials through calculations to provide this student with better services." Xu Mang said: "Deep level The optimization needs a period of research and development..."

"Because it takes about two weeks to make a special mathematical model and then calculate the data through the cosine formula..." Xu Mang said this, glanced at the astonished deputy director, and asked calmly: "You Are you satisfied with this approach?"

This...

Is the IQ of liars these days at the graduate level?

"you..."

"You..." the deputy director of the Materials Department of Tsinghua University asked cautiously, "Are you really from the Institute of Materials Science and Computer Science?"

"Yup!"

"Didn't you see the work permit?" Xu Mang asked curiously, "What's wrong? What's the problem?"

The deputy director glanced at the work pass on the table, is this really a work pass?This is [-] times rougher than the meal card ten years ago!

"This institute really exists?" the deputy director asked, "What kind of honorary deputy director are you really?"

Xu Mang: °ー°〃

Did he treat me as a liar?

Then I talk so much for nothing!

"I'm really not a liar!"
