Fengchao listened carefully to the recording of the two, and to be honest, if it wasn't for the delay of keyboard application, he would have the potential to debut as a comedian, and his improvisation skills would throw off the electric eel man.

"It seems that you are not only stupid, but also naïve."

This is also what Fengchao wants to say to Chen Bo, the challenge letter has obviously been delivered, why is there no movement at all, excited? Nervous? Afraid? Fear?

I can't see it! Everything is as it is, as if it didn't exist.

"Where's my challenge letter?"

Maple Nest tracks the whereabouts of the challenge letter, and the thermal location is displayed in a rental house in the city.

"It turned out to be falling, no wonder."

The leaflet is made with a special pigment, and when you get it, you can't see any difference, and it takes a few hours of oxidation to gradually fade the paint on the surface before the real content is revealed.

Accidents happen from time to time, and it's not like there hasn't been a similar fork before, and it's the most frequent thing to be taken by a guy who doesn't know what to do, and thrown into the trash can on the side.

For Chen Bo's identity, Maple Nest didn't dare to play 100% of the package ticket, except for the memory that shouldn't belong to him, it was difficult to hook it up with that doctor for other actions, and Maple Nest even wondered if there was something wrong with his cognitive analysis system.

Or, the doctor has a hidden second personality, and Maple Nest knows that human nature is complex, and now with the help of a framework built up from intertwined Internet data, he can easily find out the hidden attributes of anyone.

What you say, what you think, what you say and what you do, can't escape from the palm of Fengchao.

But Chen Bo did not belong to this era after all, and the information retained at that time was very limited, and there was some bias and mistakes, which led to the omission of some key information, and then the error of judgment.

Fortunately, Chen Bo turned on the mobile phone recording function, and Fengchao was able to dig deeper, and he firmly believed that as long as it was not the real body, sooner or later there would be a time to reveal the stuff, even if it was a casual moment, it would be keenly captured.

A second challenge letter is on the way, and we are sure that we will get a response soon.

"Old Shen, the West Coast responds to network fluctuations, and the server status is unstable."

Shen Yueming understood: "I have reported to the headquarters, and the preliminary judgment is that the cause is the submarine cable, and the satellite has detected that there is submarine volcanic activity nearby. ”

"Do we need to do anything urgent?"

Shen Yueming patted his shoulder and said, "Leave it to the professionals to deal with." ”

……

"I'm telling you, I had a dream that I had eight-pack abs on me." Chen Bo danced with his hands in a daze.

Wang Xu poured cold water and said: "Eight pieces are too little, the meat on your belly, I will put a screen for you, and I want hundreds of pieces to be made." ”

After taking the preventive injection in advance, Chen Bo is not so empty, the computer is inseparable from mathematical thinking, since he can mix into an excellent code farmer, his mathematical skills are usually not bad.

As a person who barely passed the fourth level of college, Chen Bo was forced by the code to teach himself an English manual, and developed a unique accent that only he could understand.

Teacher Xu wore a polite sandalwood-framed round glass, and his eyes revealed the vicissitudes that should not be at this age, and he coughed lightly twice on the podium.

"Ladies and gentlemen, good afternoon, I am your teacher, named Xu Bowei, a senior leek, self-proclaimed proficient in mathematics, statistics, economics, in his early years, he was addicted to the stock market, lost all his family property, and had no choice but to become a university teacher to pay off his debts."

"How is it different from the usual script?" Chen Bo was stunned, "What happened between the time he lost his family property and became a university teacher?" ”

"Mr. Xu Bowei is different, and it is easier for people to publish papers in core journals than to drink water." Wang Xu helped him fill in the blanks.

Chen Bo was surprised: "Really? Many people don't necessarily get into it for a few years, and some rely on student scientific research, and they make a name for themselves, what direction Xu Shenxian is studying. ”

"Leek harvesting, I have studied the model for more than ten years, and I have successfully gone bankrupt, and I like to mention the title of millionaire."

"Didn't that theory prove to fail?" Chen Bo is a little confused.

Wang Xu commented pertinently: "The methodology is indeed wrong, but the tools for studying methodology are worth learning, and the dynamic model we used in class is the evolution of his stock trading back then." ”

Mr. Xu introduced the specifications for the use of dynamic models on the podium, and Chen Bo listened to a few words and began to study them.

The system comes with all programming software, and also simplifies the operation process.

Chen Bo knew the entry-level example questions well, and what surprised him even more was that the programming actually supported Chinese operation.

[if "keyword appears {in}"]

[then "reply {not in}"]

Chen Bo pressed the diagram and replied automatically as the demonstration of the example questions.

Chen Bo, who drew inferences from one another, made up a few paragraphs of code with different content according to this grammatical logic, and it can still run normally.

Xu Bowei felt that the students majoring in keyboard application were gifted and could learn many things without a teacher, so he skipped a lot of links and went directly to practice.

"Next, please try a practice question, 3 wins in 5 games or 2 wins in 3 games, which has a greater chance of winning."

Chen Bo thought about it roughly, and there are two ways to solve the problem, the first is to assume that the sample size is infinite, and judge the winning probability of the two according to the calculation and deduction results.

But this will ignore a serious problem, the question does not give the two of them each win rate, if one side has a 100% win rate, then it is still a calf, raise the white flag and play GG.

So Chen Bo honestly chose the second path, modeling with code.

At the beginning, the benefits of [Rattan Armor] were planted because Chen Bo did not understand the game mechanics, and there were too many uncontrollable factors, so it was difficult to intuitively judge the advantages and disadvantages between the two through a model.

However, the winners and losers are different, and only the difference in the winning rate needs to be considered, and the workload is relatively small.

If you want to be a qualified code farmer, ability is important, thinking is also the key, many times the starting point of modeling is wrong, like in the inaccessible suburbs to build a gorgeous commercial plaza, although the facilities are complete, but there are few passengers.

"If the winning rate = P first, then when P = 0.5, no matter which winning method is used, the probability of winning is 50%."

"Set P>0.5 again, and the probability of winning 2 games in 3 games is the square of C23×P × (1-P) + the cubic of C33×P."

"The probability of winning 3 games in 5 games is the 3th power of C35×P× the square of (1-P) + the fourth power of C45×P× (1-P) + the fifth power of C55×P."

"I'm such a genius, I remember the formula of the combination." Chen Bo carefully checked it, confirmed that it was correct, and threw it into GitHub to generate the model.

After the drawing of the programming calculation results was completed, Chen Bo showed a pleased smile.

"It's time to get it right now."
