The metamorphosis skills are in hand, and the next troublesome tasks don't seem to be so annoying anymore.

As a result, after reading the task description, the little fifth brother was stunned.

It's not too hard, it's too easy!

[Unlock Task: Use high school mathematics knowledge to solve the following IMO problems of the International Mathematics Olympiad]

A sequence, a function, a Euclidean geometry.

It is certain that the superprogram is superordinate, but it is not supersyllabic to the extent that it needs to be partial differentiation and Fourier, for Fang Xiaowu, who can get a perfect score of 150 in mathematics in the college entrance examination, the difficulty is only trial and error.

Spread out a stretch of straw paper, start the holistic learning, and start the calculation!

A0 is a multiple of all 3s.

Because An-1 is determined only by An, it ......

Observe......

In particular......

Recursive ......

Therefore......

The conclusion was confirmed.

It was very difficult to tinker with a question for more than an hour, but it was finally proven, which made the little fifth brother feel very happy.

In a small way, it's a sense of accomplishment.

To put it mildly, there is no difference in essence between conquering the subject and conquering the woman, anyway, it is to let the brain secrete dopamine.

The little fifth brother stretched his waist, looked at the mirror, smiled, and said to himself: Handsome guy, you are a good boy with noble pursuits......

Zuo Zhesheng came back just to see this scene, and sent a bottle of peasant women's spring upside down.

"Little Wu, what are you busy with?"

Zuo Dashao sometimes can't wipe his face and call Xiao Wu Ge, especially when there is a sister present, he shouts Xiao Wu smoothly.

Of course, Fang Xiaowu didn't care about this with him, he just calmly pushed away the water bottle and asked casually, "Is there a hundred-year-old mountain?"

"Huh?!"

Zuo Dashao was stunned and muttered, "Don't you like to drink this?"

"Baisui Mountain gives a lot of advertising money. ”

Fang Xiaowu gave a concise explanation, which was so reasonable that it made people speechless.

Seeing Fang Xiaowu take out his wallet and turn over the money, Zuo Dashao's face turned white, and he turned around.

"Little Fifth Brother, you are busy first, I'll go next door to help answer the phone!"

The guy who got in the way ran away, Fang Xiaowu smiled evilly, and continued to work on the question.

Three questions, the difficulty is increasing, and the last Euclidean geometry is simply tormenting to death.

Listen to this solution -

A hunter and an invisible rabbit play a game on the Euclidean plane.

It is known that the starting position of the rabbit A0 coincides with the starting position B0 of the hunter, and after the n-1 turn of the game, the rabbit is at point An-1 and the hunter is at point Bn-1.

The following events occurred in sequence:

(1) The rabbit moves to the point An so that An-1 is exactly 1 distance from An.

(2) A positioning device feeds back a point Pn to the hunter, and the only thing that the device can ensure is that the distance between Pn and An is at most 1.

（3）……

（4）……

Ask: Is it ......

Fang Xiaowu was so annoyed that he asked a question: What kind of fucking feeling is it to be stuck in an inexplicable rabbit catching math problem?

Halfway through typing, I found that there were similar questions, more than 200 answers, all of which were various accusations.

Turning two pages and looking at the miserable situation of others, Fang Xiaowu laughed for a while, and finally used the pain of the scumbags to find the motivation to continue to climb the peak of the top students.

Let's move on......

Stuck until more than 3 o'clock in the morning, and finally solved this problem, accompanied by the surging dubbing of the system heat, dopamine secretion reached the threshold, and the little fifth brother flew cool!

[The unlocking task has been completed, and the host can choose the next reading]

After completing the task, the little fifth brother's sleepiness was drowned out by the excitement, and he immediately stretched out his claws to another long-coveted book.

A real feast.

The Beauty of Mathematics, Second Edition, People's Posts and Telecommunications Publishing House, by Wu Jun.

Mr. Kai-Fu Lee commented on Wu Jun as follows: Among the top researchers and engineers I know, Wu Jun is one of the very few people who has strong narrative ability, has a deep longitudinal insight into the development and changes in the fields of science and technology and information, and can also make effective summaries.

And Huang Erfeng is even more praised, he said: One can be removed, Mr. Wu's scientific research strength is not the top, but the ability to put into words, in the engineer does not think of the second person...... Don't talk about Da Liu, it's not the same thing.

This "The Beauty of Mathematics" was recommended to him by Huang Erfeng, and the original words were: You are already a little late in reading this book, but it is not too late to read this book.

So highly regarded, it is natural to take a look.

When Fang Xiaowu finished reading the preface and the first 20 pages, he made a decision - this book must be on the reading list!

"The Beauty of Mathematics" is about mathematics, but it is far more than mathematics, from the origin of numbers and information, to the mathematical principles behind the processing of information by search engines, to the wonderful mathematical applications in speech recognition and other fields.

A brief look at the chapter headings –

Chapter 10, PageRank – Google's democratically voted page ranking technology.

Chapter 24, Extensions of Markov Chains – Bayesian Networks (Broad Applications in Biostatistics, Image Processing, Decision Support Systems, Game Theory)

Chapter 30, Google Brains and Artificial Neural Networks.

Chapter 31, The Power of Big Data.

Why did Fang Xiaowu learn mathematics?

Isn't it just that you want to enrich your posture, find a good entry point, and participate in the tide of artificial intelligence!

There is also a small reason for wanting to use "The Strongest Brain" to gain fame and mix into Yun Zhilian to do something.

"The Beauty of Mathematics" happens to be the best combination of mathematics and information engineering problems, which is not only simple to understand, but also takes into account the interests of ordinary readers, and also takes into account the requirements of professional readers for depth, which is very magical.

Fang Xiaowu's character, if you want to play it, it will be a ...... No, that's called action...... In short, the only opportunity to "read across categories" was immediately used, and the next book was designated as The Beauty of Mathematics.

Before he officially started, he hesitated for a while.

There's still a doubling card on hand, do you want to smash it in?

The main reason is that I don't know the true gold content of this book, and the opportunity to read it across classifications is very precious......

Looking at another book "The Age of Intelligence", also written by Mr. Wu Jun, the little fifth brother gritted his teeth and endured it.

Nothing to do with the content, just, which book might be more appropriate?

I don't regret deciding it, although I was quite sleepy, Fang Xiaowu still read a full 50 pages under the lamp, and Zuo Dashao didn't know when they would come back.

Buckle up the book, it's still a little unfinished, it's a good book.

The next day, all the free time was spent reading, and most of the day was successfully completed, but this time the proficiency was extremely unsatisfactory.

[You read "The Beauty of Mathematics" once and gain 4% proficiency]

However, in contrast to the poor proficiency, the rewards are extraordinarily rich.

[Learning Talent +1, Thinking Talent +1, Language Talent +1]

It looks particularly inconspicuous, but if you convert it, you can add a total of 25 points to a single talent in the whole book, and three talents are 75 points!

You must know that Fang Xiaowu's learning talent has reached nearly 80 points, and the difficulty of growth at this time has doubled compared to before!

Theoretically, this book can make the learning talent reach the extreme, in practice it is difficult to say, but even if it can only increase to more than 90 points, it is a big profit.

Could it be that I'm so provocative, and the first full-value ability is not to flirt with girls, but to learn?!
