"Pseudo-random?"

"That's right, the core of all slot machines' internal algorithms relies on one thing - pseudo-random number generators, which are algorithms used by designers to produce approximate random sequences of numbers in order to create unpredictable infinite sequences of numbers and get a result that looks random, but unfortunately this random result is not really random."

Talking about this kind of thing, Waldo immediately became excited and became gushing, "What we have to do is very simple, first of all, we need to know how the random numbers in the slot machine are matched to the playing cards on the screen, how the pseudo-random number generator uses to produce results, and we will master the secrets of a slot machine, which is like a chick who has just come out of the bath to us, and there is no cover." ”

"Well, this metaphor is a bit vulgar, but that's pretty much what it means." Philip nodded in agreement.

"The next thing we need to do is write a decipherment program that takes into account all the variables that affect the outcome, so that when we come to the casino and determine the cycle of a slot machine, we can use the deciphering program to predict how it will run in the next few hours or even days."

"To add, there must be no other human distractions during this period, such as things like the re-turning of the casino's personnel to turn on and off, otherwise we will have to recalculate."

"Yes, that's right, we chose the video poker machines because they are the oldest, and we wanted the random numbers in the program to be a little simpler, the video poker machines in these casinos were produced at the end of the last century, and the program in them was based on a theory proposed by Donald Knut in the 60s, using the Monte Carlo method, which is the so-called linear feedback displacement register, and they dealt cards in this way, which is 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 to study, in order to figure out how the code works, Philip also wrote a disassembly program, and when all the preliminary research is done, we wrote a small program, which can calculate where the casino slot machine runs, and how much time there is a royal flush, and then, it's time to act."

"I'm sorry for holding everyone back." Philip said guiltily, in addition to the fact that he was too nervous in the casino, which made the people in the casino suspicious, but also because he planned to stop after sweeping the four casinos in the end, but he couldn't stand Justina kept pouting in his ear, and he finally relented and agreed, which caused a series of troubles later.

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

"You can't be blamed for this, we all know you're not the most suitable person, but the timing accuracy of the last button is very high, and only you are the only one who has been forced by your mother to practice the piano since you were a child, and you can press a key in 0.005 seconds to maintain a hit rate of about 50%, and the rest of us can't do it." Valdo reassured, "You've done a great job. ”

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

"Hmm......"

Although Valdo has always avoided mentioning other people, he was too excited to say before and was not rigorous enough in some of the words, but he still vaguely revealed something, coupled with the quarrel between Justina and Philip that Zhang Heng heard before, it was almost certain that there was a team behind them.

But this time, both of them seemed very righteous, no one admitted it, and even Philip, who has always been a little timid, took the initiative to say, "We can give you all the more than 200,000 euros we earned this time." ”

However, when he said this, he peeked at Zhang Heng in the back row, but found 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 200,000 euros, even if 20 million euros are placed in front of him, he won't blink.

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

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

"Huh?" The two of them were very surprised when they heard this, Zhang Heng found them after the conflict between Philip and the casino, so there were only two possibilities, either they came for their money, or they had a bigger appetite and wanted to package their skills and snatch them away, and apart from these two things, they had nothing else of value on them.

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

"Nope." The two of them said in unison, shaking their heads like rattles.

"The answer is too fast, it's good, it looks like I've found the right owner." Zhang Hengdao.

“…………”

"Leave us alone, we've told you everything we can say." Seeing that he could not lie, Waldo turned to pleading.

"You misunderstood me, I am not your enemy, on the contrary, I found you just to join your team."

"Why?" Philip's eyes widened.

"You should treat me as a person who has seen an uneven road, and draw a sword to help." Zhang Hengdao.

The two routes given by the system to complete the main quest are to help Edward escape, and the other is to help Zero capture Edward, which means that there are two factions in this dungeon.

Although Philip and Waldo have never admitted that they have anything to do with Edward, it is unlikely that they belong to the latter camp based on their professions, which means that they should want to help Edward.

Zhang Heng didn't rush to stand in line, but now the two of them were the only clues he found related to Edward, he needed to get as much information as possible about Edward from the two of them, at least to figure out the ins and outs of the whole thing, and the easiest way was of course to join the organization behind the two first.

Of course, he can also directly use violent means, Zhang Heng doesn't like torture to extract confessions, but it doesn't mean that he won't torture to extract confessions, in Hei Fan's copy, he has pried open the mouth of the harder guy, if he wants to really get serious, the two people in front of him will probably not be able to last even ten seconds, but the situation is unclear now, if he really does this, it is likely to block the way to one of the camps.

This is not the situation he wants to see.

Philip and Valdo looked at each other when they heard this, and after a while, Philip spoke, "Uh...... We can't decide this, we have to ask other people's opinions first. ”
