Many people are familiar with the word feedback, but if you really want to explain its connotation, you can only look confused.

Even if the official definition of it - "the concept of cybernetic feedback refers to the process of returning the output of the system to the input and changing the input in some way, and then affecting the function of the system, that is, the process of returning the output to the input through an appropriate detection device and comparing the input quantity", most people can only put on a question mark face and angrily rebuke "can you speak human words".

But as a basic scientific concept, feedback is not difficult to understand.

Have you ever played an online game?

The operation process of an online game is a process of continuous feedback.

First of all, think of a publicly operated online game as a system.

Its input end is the computer program used by the game's creators and operators to develop and control the game.

On the output side, there is the effect that the game presents to the player.

What is feedback?

", there's a bug in this thing, I have to complain!"

"Hey, customer service, you guys can't play this game, there's a problem with XX here. Yes, that's the problem, people are stuck on the wall, and they don't move......"

"The system has been updated, I'll click on it to see. Hey, the bug was actually fixed, it's not easy, why is it so conscientious this time......"

That's a feedback process.

According to the actual game effect, that is, the output end of the online game, the player reports the situation to the company that operates the game. Then control the game company on the input side, adjust the game's input-code program according to these situations, solve these problems, and then improve its own output-actual game effect.

Let's take it as an example.

Solving bugs is a negative feedback process.

It distills the problems that arise and the negative experiences that arise and makes them available to the decision-making body. The decision-making body then decided to draw lessons from the lessons, revise and change the original decision, and adopt a different approach than the original.

The positive feedback process is the opposite.

If the game is in the process of operation, it is found that the effect is very good, and the result continues the previous plan, and also increases the efforts. This kind of feedback that reinforces the positive effect is called positive feedback.

Similar to running an online game, Richard uses spells to control these contract beasts, and there is a lot of feedback process.

For example, riding on them and letting them walk on their behalf may have such a complex feedback chain.

Giving the command "You give me to run forward", the guy carrying him ran forward, but it just drilled into the rough road, making him uncomfortable to sit on.

A negative feedback, supplemented by a corrected command "Do not run on the path". And then it did take the main road, but the speed was fast and slow, and it made him jolt.

Then negative feedback, and then the next command, "Keep the speed, don't be unstable".

At this time, if it works well, give positive feedback - "Keep running like this, don't change it." ”

As a result, a rock suddenly appeared on the road ahead, and you can't keep him running forward, so you have to give the command - "go around".

......

Through constant feedback and adjustment, they can achieve the results they need.

But if this is the case with the actual manipulation process, it is undoubtedly laborious and laborious. It's like acting for a game full of loopholes, with a lot of bugs, and the actual scolding, and I don't know where to change it.

Why is it that with such a good means of control as the spell, the Tyrant Bear is still banished? It is because of their resistant and uncooperative mentality that it becomes extremely difficult to control them, and they can only achieve the desired effect through continuous positive and negative feedback.

If even riding and commuting are so troublesome, wouldn't it be more tiring to use them to engage in more complicated fighting activities?

In contrast, the ideal situation is for them to actively cooperate and achieve the desired effect with very few instructions.

Richard didn't have much to do about it, and after thinking about it, he could only start with "carrots and sticks". Make these bastards listen to themselves with constant rewards and punishments.

In this case, two contract beasts are estimated to be easier to control than one, because they can compete with each other, and the effect of rewards and punishments will be increased.

"I'll go, sure enough, there is a sea!"

The moment Richard walked out of the jungle, he couldn't help himself with excitement, and when he saw the golden sand and turquoise waters in front of him, his heart was about to move.

He immediately let himself go.

He took off his boots and ran barefoot on the beach, roaring and screaming all the way, like a wild child.

Following him, Xiong Da and Xiong Er couldn't look at each other.

Xiong Er, the newly promoted gangster, snorted at Xiong angrily, and his blood-red eyes seemed to be questioning, "Why did you, a guy with thick eyebrows and big eyes, rebel against the revolution and become a lackey of mankind?"

Xiong Dali ignored it.

It sat on the sand, as if to say, "The wood is already in the boat, you honestly accompany the old bear and I will suffer."

While they were sulking at each other, Richard had already noticed a shipwreck that looked small not far from the beach.

Calling Xiong Da to open the way, Richard rode Xiong Er's back and assumed a triumphant posture like a victorious general inspecting his trophies.

Poor Xiong Er, who was carrying him, had to take him to sweep his lair on the first day of his surrender.

Unlike the bear, who has his home in a cave, he chose to build his nest on a shipwreck on the beach because of the long stretch of coast in the site.

Xiong Er walked slowly, and he turned his head to look at Richard on his back, and was very stunned that he had been subdued by such a useless human.

The more I thought about it, the more angry I became, the more angry I thought, the more I trembled with emotion, and I wanted to throw Richard on a big horse. But recalling Richard's previous method of teaching it, Xiong Er couldn't help but shudder. The cold and suffocating feeling made it unwilling to experience it a second time.

The bear is under the eaves and has to bow his head.

The strange thing is that when they killed one person and two bears to the shipwreck, suddenly there was light in front of them.

The iron sailing boat, which was lying on its side on the beach and turned over, suddenly the dilapidated hull of more than 40 meters was illuminated by something inside.

Even now that the sun is shining above, this blue light is so bright that people can't open their eyes.

"What's going on......"

When Richard was about to shout back to the big bear in front of him to "escort", a large firefly-like point of light flew out of the blue light, like a dotted star in the summer night sky.

The points of light gathered and suddenly took on a human-like shape.

A moment and a half later, what appeared in front of Richard was a bull-headed devil with wings on his back, spiral-shaped horns on his head, and snake scales.

It was bathed in a faint blue flame.

At this moment, it appears to be fully twenty meters tall.

Seeing Richard below, the bull-headed devil-like giant made a dull, bell-like sound, extremely penetrating.

"Finally met someone here......"
