Chapter 351 The Meaning of Pseudo-Random
The journey on the road was very fast, during which Jing Yu was a little tired, so she leaned in Zhang Hao's arms and took a short rest.

Looking at Jing Yu's sweet smile in his arms, the softest part of Zhang Hao's heart was suddenly touched.

Zhang Hao gently stroked the hair hanging on Jing Yu's face, at this moment, he just wanted to protect her quietly.

The car arrived in Shanghai safely, and Zhang Hao sent Jing Yu back to Fudan University. After thinking about it, he didn't enter the gate of the University of Finance and Economics, but went straight back to the training base.

"beat!"

"Up, up!"

"Nice!"

...

Zhang Hao smiled, it seems that everyone is training seriously, and he should work harder!

Seeing Zhang Hao, several people stopped what they were holding, and just pushed the crystal to relax a little.

"Ha, Ah Hao is back, how about his father-in-law and mother-in-law?"

"Xiaohao, are you engaged?"

Everyone laughed and teased Zhang Hao, and the atmosphere was peaceful. Zhang Hao cursed with a smile, and briefly talked about the situation of returning home this time. Everyone was happy for him. There is nothing happier than the approval of both parents.

But Chen Yi didn't speak, just sat silently, studying things.

"What is our big analyst doing?"

"Hey, this guy has been studying barbarians recently. He customizes himself every day, and then cuts the little soldiers back and forth. I think he is crazy!"

"Oh?" When Zhang Hao heard this, he immediately became interested. What is there for Manzi to study?It seems to be the case.

"Chenshen, what are you busy with?" Zhan Huo approached Chen Yi, and saw that the place was densely piled up with pieces of paper, all kinds of data analysis, Zhang Hao felt dizzy just looking at it, it seemed that Chen Yi's professional attitude was He is far beyond comparison!

Seeing Zhang Hao's arrival, Chen Yi smiled: "I'm studying Manzi's crit situation, in this way, as long as I control it properly, I can roughly estimate the time of Manzi's crit, and ensure that the output is maximized during duels!

When Zhang Hao heard it, he immediately understood, the barbarian's critical attack?Isn't this just a matter of probability!

"The barbarian's critical attack is completely random. Everyone knows the critical attack by looking at his face!" Er Hong also came. To be honest, he didn't understand Chen Yi's research this time, and everyone knew that he was full of anger. Barbarian, without equipment, the chance of critical strike is 35%.

Chen Yi shook his head: "No, actually Manzi's critical strike is a pseudo-random attack!"

"Pseudo-random?" Zhang Hao didn't understand. Chen Yi has always been a guy who doesn't startle and talk endlessly. I don't know what happened to the [pseudo-random] proposed this time.

辰逸倒也没有卖关子，拿出研究的数据道：“这是200刀的数据，出暴击的刀的序号是4、6、11、15、19、21、23、28、30、31、35、38、41、46、

48、52、55、57、64、66、70、71、75、76、82、83、87、90、93、94、95、97、99、103、106、108、111、113、116、118、122、127、131、134、135、142、144、147、151、153、154、156、159、161、

165、166、168、172、177、180、184、188、190、193、194、196、198”

"A total of $69, 34%. It seems that Riot's designer math was not taught by a physical education teacher. The data is not deceiving!"

"That's right, did I just say it's random! The probability must be no problem!" Er Hong was very happy as if he had discovered something.

Chen Yi shook his head again, and continued: "But after I observed it, I found something different. You look at the situation of the 69 knives, and then took out the data. Zhang Hao and others looked at it, densely packed, very detailed:
11 Knives The first critical hit after a critical hit
21 Knives The second critical strike after the critical strike
14 Knives The third critical strike after the critical strike
16 knives are the fourth critical hit after the critical hit
5 knives are the fifth critical hit after a critical hit
1 knife is the sixth critical strike after the critical strike
1 knife is the seventh critical strike after the critical strike
Chen Yi continued: "In other words, it is the following data." After speaking, he took out another table:

First knife crit, 15%

Second knife crit, 30%

The third knife crit, 20%

23th Knife Crit, 18%

Fifth knife crit, 07%

Sixth Knife Crit, 01%

Seventh Knife Crit, 01%

In other words,
15% critical strike on first strike

The first knife does not explode and the second knife explodes 36%

Third knife 37%

Fourth knife 69%

Fifth knife 71%

Sixth knife 50%

Seventh knife 100%

"Pseudo-random is a very strange thing in my eyes. Because the normal situation is the same as the normal random number according to its operating mechanism. The error will not be very large."

"In many cases, pseudo-randomness also narrows the character gap... It gives a lot of people with really bad character a slight advantage..."

"If you really want to test, then at least cut 2000 knives, and then look at the data. On the other hand, you must carefully calculate the probability and mathematical expectation of each knives on the paper. Look at the degree of matching, and then see if it is random. Didn't research it..."

"This..." Zhang Hao was speechless for a moment. He didn't expect Manzi to have so much knowledge when he cut people.

However, Zhang Hao thinks about it, many times the crit of the barbarian really feels like this. As long as a few hits fail to get a crit, the probability of a subsequent crit will really increase. In this way, the seventh hit with 100% crit Hitting rate is not unreasonable!
"Chen Shen, are you going to use Manzi to play?" Er Hong asked curiously, otherwise, why did he study Manzi so hard?
"En..." Chen Yi responded and nodded, indicating that Er Hong was right.

"The setting of LOL should be pseudo-random, so that the overall crit is balanced, reducing the outbreak of character."

Zhang Hao looked at the information in his hand and listened to Chen Yi's explanation, it seemed reasonable, at least from the point of view of the barbarians, this kind of research is still very reliable.

"Well, what is pseudo-random..." Er Hong asked weakly.

"This is very complicated, but I can make it a little simpler..."

Chen Yi continued: "First of all, let's start with random algorithms. Random algorithms are everywhere in our lives. If we regard a quantitative as an algorithm, then most things are random events."

"For example, our hair, the trees on the street, whether we can win the lottery, these are all random algorithms"

"The simplest example is those random number generators on the Internet. There is actually a formula behind these generators, which can make the range and value range from positive infinity to negative infinity, and the value range and value range are synchronized. Change, this formula is very complicated, I don’t know.”

"First of all, we need to understand that computers only calculate according to the logic designed by humans. There is no way to achieve true randomness. The randomness in the game is fake. No matter what, the randomness in the game is not real, and It's computer-controlled pseudo-random."

"There are two types of pseudo-randomness. Let me explain briefly. One is to simulate a real random situation as much as possible, such as using a computer to simulate a weather forecast. The randomness in this case is not real."

"Because we have already input specific results, no matter how random the computer is, it will only thunder and rain or whether there is a sun or not. It is impossible for the computer to simulate the weather like RMB falling in the sky, because the program does not give it such results. So while it looks real, it's actually fake, pseudo-random.)
"

"The other is pseudo-random, which contains certain specific rules. This kind of random is widely used in competitive games, which is what we usually call the critical strike rate. The critical strike rate has a fixed value."

"But it is actually random controlled by the program, it is pseudo-random. - The critical strike is not really determined by the value written on our panel as we imagined. Let's take the barbarian as an example. Every attack of his The result (whether a critical strike or not) will affect the chance of a critical strike in the next attack."

"In this way, each attack is not an independent event, because it is affected by what happened before, and for true randomness, or the former pseudo-randomness, each attack should be an independent event!"

"Specifically, for a certain random prop/skill, there is an initial probability called c. (It is different for each prop/skill) For example, the crit of the barbarian."

"The crit chance of his first attack is c. If he doesn't get a crit, then the next attack, the system will increase the crit chance to 2c. If he hasn't got a crit yet, then increase it to 3c!"

"Until there is a critical strike, then everything starts again. The probability of the next critical strike returns to the initial c. (Obviously, if there is no critical strike, then after a certain number of attacks x, x*c>1 then This time there will be a critical attack)”

Chen Yi thought for a while, and concluded: "Actually, pseudo-random is born for the purpose of balance, to prevent the cheating incident of continuous crit after crit. , You can still get a critical strike with a knife, which is terrible."

"And there will be a lot of knives that still don't crit, which will make the game very chaotic. The pseudo-random appearance is just a neutralizing patch..."

Zhang Hao thought for a while, and said, "True randomness means that each calculation of probability is an independent event and does not affect each other."

"Pseudo-random means that every calculation probability is related. The trend is to make the weighted average in the final sample pool infinitely approach the probability set at the beginning. Is this what it means?"

Chen Yi nodded in relief, very happy with Zhang Hao's understanding.

"You two, that's enough..."

Erhong has been unable to complain, this is really just a game, okay...
