After Zhang Qin left, Rococo suddenly felt cold all around.

The light tube above her head suddenly flickered, which made her feel that the atmosphere had suddenly become a little weird.

It's not that she's not bold enough, but she's not afraid of 10,000, just in case.

No wonder she felt that Tang Yu's temper was a little too good. For example, as mentioned before: Luo Li took the telescope out to play in class, and Tang Yu continued to teach with a smile. This may be because the students he taught once jumped over the building, so it left a lot of psychological shadow on Tang Yu, and now even if he sees students being naughty in class, he is not very willing to discipline him.

"What do you think?" Tang Yu suddenly appeared behind Rococo, and patted Rococo on the shoulder, which immediately startled Rococo - how could this person walk without sound! it!

When I came back to my senses, "I didn't think about anything. ”

"I have something to do temporarily, I may have to go back first, why don't you go back to work first, and I'll explain it to you tomorrow?"

"Yes, no problem!"

After listening to Zhang Qin's words, to be honest, Rococo didn't want to stay in this ghost place anymore.

Grab the test paper and pen, and as soon as you smoke it, Rococo disappears around the corner of the stairs.

"Uh......" Tang Yu was stunned. I don't know why. But when she was talking on the phone outside, she seemed to see Zhang Qin.

……

QQ battle platform, manager department.

"Xiao Qin, just now you said you had something to tell me, what is it?"

As the manager of the QQ battle platform operation, sitting in such a high position, Xiong Dawei should be high-spirited, and even if he is not high-spirited, the manager's position should be happy, but at this moment, Xiong Dawei looks a little depressed, and he scratches his hair on the top.

No, their performance this month.

Completely eaten to death by other battle platforms - especially Hao Fang. After all, Haofang battle platform has a deep historical heritage. Players think that the players who play on the Haofang battle platform are masters,Only a few players who don't care about the level,Choose to stay in their QQ。 And although the background of the QQ battle is also quite strong, with Tencent's support, if the performance has not been able to improve, Xiong Dawei himself can only resign.

"Could it be that someone wants to quit again?"

Because Xiao Qin is in charge of personnel, this is the only thing Xiong Dawei can think of, he raised his eyebrows and looked at Xiao Qin.

If that's the case, then this is the fifth time they've wanted to quit this month.

It's not because the salary is not enough, Tencent's job is still okay. Rather, many people believe that staying here will only waste their talents.

Xiao Qin also understands Xiong Dawei's difficulties, but this time, it's really not a resignation!

"Mr. Xiong, I received this in our personnel mailbox today, and I think it is necessary for you to take a look."

Xiao Qin pretended to be mysterious, which made Xiong Dawei twist his brows, and he still came to sell Guanzi at this time, I don't know if he is very worried now. Don't...... Do you see any great people applying for their positions?

No, Xiong Dawei thinks this is unlikely, because the old friends who were pulled over by him before are now almost gone, except for the only remaining technical backbone - Lao Zhou.

"What is it?"

Xiong Dawei picked up the things that Xiao Qin had printed, shook them, and looked at them like an old pedant reading the newspaper.

'Suggestions on adding Chenghai 3c ranking system to the QQ battle platform. ’

At first glance, this is a topic, huh...... The title is written very smoothly. However, after reading it thoroughly, it didn't give Xiong Dawei much shock. Or, for the time being, there has not been anything Xiong Dawei wants, naturally, of course, he will not be too interested in this thing.

But! Since Xiao Qin brought it over for him to see, Xiong Dawei also continued to watch it seriously. And in the text, immediately after that, there is also something similar to a summary.

Abstract: The so-called 'ranking system', in short, is a system used to rank players.

Nowadays, all major online games, whether they are large or small, will have level lists, PK lists, equipment lists, red lists, black lists, etc., but only in competitive online games, such as: Chenghai 3c, war3 These games, it is difficult to see a real ranking.

Hao Fang battle platform in this regard,Take the lead in seeking change,The first two years put forward the concept of game points and account level,The higher the points、The higher the account level,The more privileged it is,It's a pity that the brush is rampant,Many times we see,Hundreds of thousands of points of people,Basically, the players themselves brushed。

In order to reflect the privileges, use the privileges to pretend to be forced, which is far from the original intention of the designers of the Haofang battle platform.

To this end, the author here to Chenghai 3C as an example, put forward a new ranking system that is different from Haofang and other battle platforms to rank the strength of players, for your reference.

After reading the 'summary' and the 'background of the proposal' at the back, Xiong Dawei didn't read it, because what he said with the summary was the general meaning, and he was engaged in this line of work, didn't he know more than this 'author'?

Xiong Dawei looked directly at the more core part, 'the preliminary idea of the ranking system'.

Initial Idea of a Ranking System: Before the establishment of this ranking system, the author's idea came from the current ranking system for chess tournaments, the elo system. elo is a rating system invented by an American physicist ArpadElo, which is used to judge and distinguish the strength and ability of players. It was first used in chess activities, and after continuous practical use, it was found to be an extremely accurate evaluation system, so it was quickly recognized as the most authoritative grading system.

What is the difference between ELO and the general evaluation standards - ELO has different calculation methods in different fields, we take Chenghai 3C as an example.

If Chenghai 3C does not have elo, players generally host the game by themselves, open a room and wait for players to join the game, then the unequal competition with the strong and the weak will continue to be staged, players can deliberately choose the game or form a team to face scattered players, a player who wins more than a thousand, may just be a player who specializes in picking a novice as an opponent. He may even invite other friends who are also veterans to wait for their prey to win easily.

Unequal strength has always been the culprit that destroys the fun of competition, and the ELO system is a big secret recipe to solve this problem!

What is the ELO system? How does it work? In a nutshell, the ELO system is a system in which points are added for winning and points are deducted for losing, when a base value is determined.

We can set the initial strength of each player as a number, for example, 1200, before the player plays, we will set up a library, put all the players with the initial strength around 1200, and put it together with the player, let's say A, and then randomly draw one of the players from the pool of many people to play against A.

If A wins, it means that it is better than the players with similar strength to him, and he will get extra points; But if A loses, it means that it is slightly inferior in strength among players with similar strength to itself, and points will be reduced. In this process, the stochastic system stress keeps A's win rate at 50% during the matching process, and this reason will be explained later.

The elo system, through which players are randomly matched with opponents with similar base scores, can make the game more fair.

It can be expected that under the elo system, players who are obviously too strong will stand out from the general players because of the continuous increase in the base score, and the final score is getting higher and higher.

This is the ELO system.

Then, in order to make the elo system more intuitive, Rococo also illustrates it by drawing.

Xiong Dawei read it for the first time, and then continued to look back at it for the second time, and after reading it for the second time, he started from the topic and watched it for the third time.

When Xiao Qin saw his manager like this, he knew that their manager had also fallen into the devil, and he was deeper than him, because Xiao Qin was also like this before. In fact, at the beginning, Xiao Qin didn't want to look at this thing, after all, he didn't understand the technical things, but it didn't matter if he didn't understand, the key was that the QQ battle on their side was too boring and boring! Then, Xiao Qin treated it as an exam question, a little bit of consideration, a little bit of consideration, I wiped it, and in the end, what he didn't expect was that he seemed to have found gold.
