Omnipotent Data

Located near Tsinghua University, this Internet cafe called Celadon.

Cheng Nuo took out the last "History of Modern Mathematics" from his schoolbag, and then put on a headset, turned on the computer, and created a word document in the awkward gaze of a few chicken-eaters nearby.

""Preprocessing Method for Joint Compact Difference Discrete Equations of Two-Dimensional Helmholtz Equation""

Cheng Nuo put the title of the topic on it.

Rub your hands, move your fingers, and twist your neck. Cheng Nuo was doing warm-up exercises.

On the left hand side, there is a whole stack of seven or eight reference materials.

On the right hand side is draft paper, gel pen, ruler, eraser...

Everything is ready, just start work!

Cheng Nuo didn't waste any time, according to his plan. For a whole day today, he intends to complete at least 20% of the tasks he is responsible for.

There will be classes after the November holiday, and things will get busier. There is not much time left for Cheng Nuo!

Clicking on the song "Where is the Xueba?", with the dynamic music from the headset, Cheng Nuo started his project work.

"There is a guy in our class who is very cool. Learn to dominate, who dares to block the way."

"Students have been reading books, even running to the toilet."

…………

"Xueba, Xueba, where are we going? Will we test God in the exam tomorrow?"

"Student scum, learn scum, don't read it again! You can't remember after reading it!"

Cheng Nuo hummed the lyrics in his mouth and crackled his hands on the keyboard.

Discrete one-dimensional helmholtz equation in d format to derive two-dimensional helmholtz equation, we must first understand what the one-dimensional helmholtz equation looks like this handsome little girl.

More than a year ago, there was a project that specifically studied the one-dimensional Helmholtz six-order compact difference method.

Therefore, Cheng Nuo can directly refer to that topic paper for some things about the one-dimensional helmholtz equation.

First, consider the one-dimensional helmholtz equation with dirichlet boundary conditions.

f\'\'(x)+k^2f(x)=g(x), x∈Ω=(0,1)

f(x)=0∈αΩ

k represents the wave number.

Next, divide the domain into...

Cheng Nuo's brain was spinning fast.

The seven or eight books placed on Cheng Nuo's left were flipped back and forth by Cheng Nuo, looking for the information he needed.

As for the stack of draft paper on the right hand side, Cheng Nuo would not normally use this stuff.

Because, whether it is the college entrance examination or the questions given by the mathematics teacher in the classroom, they are too simple to be worthy of Cheng Nuo's use of "draft paper", a treasure of the bottom of the box.

But it's different now.

In just one morning, Cheng Nuo had used more than ten draft papers.

Every piece of draft paper is full of formulas that make ordinary people look like ghost symbols.

The progress of the subject is also moving in a gratifying direction.

Although Cheng Nuo's brain is wider than ordinary people, it is still not free from humans.

Cheng Nuo was only a freshman, so this time, Cheng Nuo didn't do it as usual. Once he got the subject, he just handled it with ease.

With the support of the powerful computing power of the brain, Cheng Nuo is hard to say, but it is not easy.

Inside the celadon cafe.

Cheng Nuo's existence like a clear stream still attracted the attention of many people in Internet cafes.

Because Cheng Nuo was sitting in the Internet cafe near the door. So whenever a new customer comes to the door, Lu Chengnuo will notice: a young teenager in a small grade, flipping through the book quickly, while writing and drawing. His hands are still frowning, thinking hard, and sometimes smiling.

From time to time, he laughed loudly, "Wow Ka Ka, I should use this formula, I'm so embarrassed!"

? ? ?

Could it be that I... went in the wrong place.

Customers who want to eat chicken are dumbfounded.

Of course, some people were curious and walked behind Cheng Nuo to see what Cheng Nuo was up to.

As a result, when I saw the dense and complicated formulas on Cheng Nuo's computer...

Gangster! Gangster!

rbq, rbq! Really can't afford it!

Goodbye, don't send it!

Under Cheng Nuo's aura of Xueba, the scumbag automatically retreated!

…………

At noon, Cheng Nuo was too lazy to return to the dormitory, so he ordered a takeaway.

"Man, help me look at things for a while, I'll go down and get the takeaway." Cheng Nuo patted the shoulder of the man sitting next to him, and said with a smile.

The buddy sitting next to Cheng Nuo is a thin man with glasses and a sallow face.

It looks like a "friend" who has been in love for more than five years.

That buddy had been playing chicken-eating all morning, and forcibly completed a game of skydiving.

"No problem. Xueba boss!" The young man gave Cheng Nuobi an ok gesture, then touched his stomach, muttering to himself, "I'm a little hungry."

When Cheng Nuo came back with the takeaway, he saw that buddy was sucking instant noodles and was eating rightly.

Cheng Nuo sat down beside the buddy, turned his head and said painfully to the young man, "Guy, this paper bowl for instant noodles is unhealthy. Uh... I heard from an expert."

The young man laughed, while sucking the instant noodles, and was finally vague, "Healthy? Haha, does that expert know instant noodles? I am so confused about eating instant noodles and I still care about health!"

Cheng Nuo couldn't refute the young man's words.

"Stop talking, stop talking, eat, eat."

Cheng Nuo rubbed his hands, swallowed and opened the takeaway bag.

Inside... is a bucket of fragrant instant noodles~www.readwn.com~ The discrete one-dimensional helmholtz equation in format is obtained as follows: af:=……(ㄒoㄒ)/┏(゜ロ゜;)┛……”

Crackling, crackling~~

The sound of Cadence's fingers tapping the keyboard sounded throughout the Internet cafe.

It's just that some people are playing and some are learning.

"F=[f1,f2……fn]^t,f\'……"

"Huh, finally got it done!"

At seven o'clock in the evening, Cheng Nuo's one-dimensional Helmholtz equation in d format was worked out. What a sense of accomplishment!

I planned to use two days to get the one-dimensional one out, but I didn't expect it to be in good condition and cut the time by half.

So tomorrow, you can start exporting two-dimensional work.

Night had come long ago, and the streets outside were already brightly lit.

Cheng Nuo remembered that he was too involved in writing and had not eaten dinner yet.

Stretching, Cheng Nuo took off his headset. As soon as he looked up, Cheng Nuo found that almost everyone in the Internet cafe was not playing on the computer, but raised their heads one by one, looking at the big screen in the Internet cafe.

The big screen is the final of the lpl professional league.

edgvrng.

The score, 1:2.

At this point, it has come to the end of the fourth game. rng has an absolute advantage.

A perfect group of five people on the high ground, destroy the four opponents, push up the ground, and break the front teeth.

boom--!

When the blue crystal shattered, the commentator shouted in the loudest voice: "Let us..."

"Congratulations rng!"

The entire Internet cafe is boiling.

ps: Congratulations to rng for winning the 2018 LPL Spring Festival Championship!

Congratulations to uzi for winning the spring playoffs mvp!
