Chapter 388

"Pseudo random?"

"Yes, the core of all slot machines' internal algorithms depends on one thing - pseudo-random number generator. Pseudo random number generator is an algorithm used by designers to produce approximate random sequence, so as to create unpredictable infinite sequence and get a seemingly random result. Unfortunately, this random result is not really random."

Talking about this kind of thing, Waldo immediately got excited and became eloquent. "The thing we need to do is very simple. First of all, we need to know how the random numbers in the operation program of the slot machine correspond to the playing cards on the screen one by one, and how the pseudo-random number generator produces the results with efficiency. If we master these things, we will also master a computer The secret of the slot machine is that it's like a chick just out of the bath to us, and there's no shelter. "

"Well, this analogy is a bit vulgar, but it's about that." Philip nodded in agreement.

"Next, we need to write a decipherer that takes into account all the variables that affect the results, so that when we come to the casino and determine the running cycle of a slot machine, we can use the decipherer to predict its running status in the next few hours or even days."

"In addition, during this period, there will be no other man-made interference factors, such as the re opening and shutting down of the casino staff, otherwise we will have to recalculate."

"Yes, that's right. We chose video card games because they are the oldest models. We hope that the random number in the program can be generated more simply. The video card games in these casinos were all produced at the end of last century, and the program in them is based on a theory put forward by Donald Knut in the 1960s, coupled with the Monte Carlo method, that is to say, the result of simulation So called linear feedback displacement register, they deal in this way, very mentally retarded.

"Well, the actual situation is not so simple. We found their code in the patent office and bought a machine of the same model for research. In order to find out how the code works, Philip also wrote a disassembly program. After all the previous studies were completed, we wrote a small program, which can calculate the old value of the casino Where the tiger will run, and how much time there will be dathun, and then, it's time for action. "

"I'm sorry for the delay." Philip felt guilty because he was too nervous in the casinos, which made the people in the casinos suspicious. In the end, he planned to stop after sweeping the four casinos, but he couldn't stand Justina's advice all the time. He finally relented and agreed, which led to a series of troubles.

Although the people in the casino have been left behind, Zhang Heng, who is sitting in the back seat with unknown friends and enemies, is obviously more dangerous.

"It's not your fault. We all know that you are not the most suitable candidate, but the time precision of the last button is very high. Only you among us have been forced to practice piano by your mother since childhood. You can press a key in 0.005 seconds to keep the hit rate at about 50%. The rest of us can't do it." Waldo comforted, "you've done a good job."

"So you have other company?" Zhang Heng asked.

"Well..."

Although Waldo has always avoided mentioning other people, what he said before was too excited, and some words were not rigorous enough. He still vaguely revealed something. In addition to the quarrel between Justina and Philip that Zhang Heng heard before, it is basically certain that there is a team behind them.

But this time, both of them seemed very loyal. No one admitted that, and even Philip, who had always been a little timid, took the initiative to say, "we can give you more than 200000 euros this time."

However, when he finished this sentence, he peeked at Zhang Heng in the back row, only to find that there was no reaction on the latter's face.

Zhang Heng is not interested in making money, because no matter how much money he makes, he can't bring out a copy, so as long as the expenses are enough, let alone 200000 euros, even if 20 million euros are put in front of him, he won't blink.

Philip gritted his teeth, "and our cheating technology, the small program we write to predict playing cards, can give you, with this thing, you can also make a steady stream of money from other casinos."

"I'm not interested in any of this." Zhang Hengdao.

"Well?" Both of them were very surprised when they heard that Zhang Heng came to them after the conflict between Philip and the casino, so there were only two possibilities, either for their money, or for their appetite, and they wanted to pack their technology together. Besides these two things, they had nothing else of value.

"Have you ever heard of a name called Edward?" Zhang Heng asked.

"No They spoke in the same voice, shaking their heads like a rattle.

"The answer is too fast, very good. It seems that I have found the right one." Zhang Hengdao.

“…………”

"Leave us alone. We've told you all we can say." Waldo saw that it was impossible to lie, and turned to plead."You misunderstood me. I'm not your enemy. On the contrary, I just want to join your team."

"Why?" Philip's eyes widened.

"Think of me as someone who sees injustice and help me." Zhang Hengdao.

The system gives two routes to complete the main task, one is to help Edward escape, the other is to help zero capture Edward, which means that there are two camps in this copy.

Although Philip and Waldo never admit that they have anything to do with Edward, they are unlikely to belong to the latter camp from the perspective of their career, which means that they should want to help Edward.

Zhang Heng is not in a hurry to stand in line, but now they are the only clues he has found about Edward. He needs to get as much information about Edward as possible from them. At least he needs to find out the whole story. The easiest way is to join the organization behind them.

Of course, he can also take direct violence. Zhang Heng doesn't like extorting a confession by torture, but it doesn't mean that he won't extort a confession by torture. In the copy of black fan, he pried the mouth of the harder guy. If he really wants to be serious, these two people may not be able to survive for ten seconds. However, it's not clear now. If he does, he will probably be blocked I've found my way to one of the camps.

This is not the situation he wants to see.

Philip and Waldo looked at each other. After a while, Philip said, "er We can't decide this. We have to ask other people's opinions first. "
