With such a fresh accomplishment from the staff below, Alice certainly couldn't leave, but she had to go upstairs and hang up a few phone calls before she could study Harry's ternary genetic algorithm at length. Pen "Fun" Pavilion www.biquge.info

First of all, for the family, James is taking everyone to Scotland for a self-drive, saying that he wants to see the deeds of William Wallace back then. Although the size is not small, how can a big brother still put a big brother's mobile phone in a car, and the phone is quickly connected.

As for the relevant content, it is natural that I have just discovered a breakthrough topic, and I may have to be busy for a few days and nights like other programmers. Therefore, when you arrive at the hotel, you can naturally save a few days and a week or two when you contact your eldest daughter. Let's pay less to British Telecom, people have made enough, although Alice has thrown tens of millions of shares away.

And then a phone call was hung up on Maiya. Let the big girl travel thousands of miles across the Atlantic, of course, you can't just stay in Exeter for a day or two and leave.

For the past few days, in addition to mixing with the mercenary security guards in the research institute, Maiya has mainly been testing the power of Alice's new gunpowder in various ways. All kinds of environments, all kinds of doses, all kinds of explosive power mixed with other gunpowder, these are all things that interest her. Not to mention when Alice handed over the "degraded version" of super gunpowder to Lockheed, no one stipulated that she couldn't do experiments herself.

"Hey honey, you ......"

As soon as the phone was connected, an explosion was heard, and then Maiya: "Alice, I just had a problem recently. Although crystalline explosives are easy to carry, they are not suitable for quantitative control, and when we mass produce them in the future, do we have to cut and polish them to different specifications in advance? ”

Hey, I actually thought of such a layer.

Alice thought about it, "You mean the field of special operations, right?" Considering the power of the explosion...... We can cut them into lenses the size of small fingernails, which is equivalent to a hand grenade, and then mix them with explosive agent plastics such as thunder mercury......"

"Ellie, I mean, is it possible to specify the crystal size of the explosives at the time of production?"

Even if she doesn't want to join the army after graduation, Maiya also thinks about it from the perspective of a professional soldier, Alice can't help but feel relieved, and laughs: "Of course, it's a specific arrangement." The solidification of the colloidal body is called crystallization, as long as the mold is ready, isn't it? The size of a fingernail, the size of a little fingertip, the size of a brick, the size of a pizza, isn't it all casual? ”

It's funny to think about, the crystalline, 20 times more powerful new gunpowder of TNT is simply born for special operations and terrorist attacks. Alice realizes that the main components of the new explosives are only nitrogen, oxygen, and trace amounts of deuterium and carbon, which cannot be detected by police dogs or existing scanners.

So it's no wonder that Maiya would think of related fields, but the terrorist attacks were not rampant at this time, otherwise there would be a lot of worries.

"That's ...... Okay, so Ellie, are you hanging up? ”

Of course, it was time to claim that I was going to retreat and meditate for a week, give notice, hang up the phone, and then go back to the fourth floor of the institute.

"It's a shame that you can actually use the ternary to make the research algorithm." Sitting down in Harry's chair, Alice said to the people around her, "Have you seen it, when you were still trying to write a calculator software in ternary coding, Harry had already made the genetic algorithm!" ”

Harry, of course, was modest: "It's just a fluke, I just had the idea of trying it out, I didn't think I would succeed." And you're the real awesome, boss, and you can tell at a glance what I'm writing. ”

"Harry is the one who has a girlfriend!" The tall and thin John laughed on the side: "You two must be getting married, right?" Otherwise, how could you think of genetics? ”

"That's it! Darwinian evolution! Harry wants to be a father! ”

Of course, the people around them are cheering happily, don't look at this algorithm is not their own achievement, but who can not be happy to make a breakthrough in the field of evidence?

Practice has proved that the difference between writing programs by ternary means and the binary era is really huge. Although it is "just" a genetic algorithm, it is no less significant than the birth of the algorithm itself in this era of terricity pioneering.

You know, algorithms are really different from just doing math problems, it tests not only the basic knowledge of the programmer, but also his way of thinking. After all, any algorithm is ultimately designed to solve a certain need.

That's why, when companies like Google and Microsoft came off in full swing, the interview questions were always so weird -- not about programming skills, but about thinking.

Not to outsiders, Alice will immediately think of a film and television example of the application of algorithms.

In the American drama "I Am a Zombie", zombies will become very pale in their hair and skin color, and while they love to eat human brains, they have an irresistible love for chili sauce - except for these two things, they eat everything that tastes the same wax.

So, the "sports drink" company that accidentally created these zombies has written an algorithm to identify how many zombies there are in Seattle -- by tracking credit card spending records, i.e., hair color, sunbathing, chili sauce products, and counting the number and frequency of their purchases.

Therefore, programming itself is a very easy thing, and what people really care about is the function of the software made by programming. With the smallest size, the strongest stability, and the highest execution efficiency, it can meet the various needs of users, which is the biggest test for all programmers.

So then, it's up to Alice to test for herself what is the difference between Harry's genetic algorithm written in ternary and the old binary.

And in this process, both Alice and other bystanders have to face a very interesting problem - the transformation of the thought process.

Just as all people who are not proficient in a foreign language should use their own Chinese language to make up for it when reading a foreign language.

Looking at Harry's ternary code, anyone would have to convert it into binary in order to achieve a higher level of comprehension, even Harry himself.

The genetic algorithm first needs to convert the operation object, that is, the variable, into a series of strings, and perform evolutionary operations on the population, so it needs to prepare some initial population data that represents the starting search point. Then, it uses the fitness calculation to evaluate the strength and weakness of each individual by the size of the individual's fitness, so as to determine the size of their genetic chance. Finally, through selection calculation, the individuals with high adaptability in the current population are inherited to the next generation of the population according to a certain rule or model.

In this process, as stated in the fundamental principles of Darwinian evolution, algorithms also need to take into account the problems of "rebirth" and "variation". That is, cross-operation, exchanging part of the "chromosome" between two individuals with a certain probability to achieve the birth of new data. At the same time, it is also necessary to use mutation operation to change one or some "elements" of an individual according to a small probability, which is also an operation method to generate new individuals.

It is this set of computational principles that makes genetic algorithms widely used in the field of artificial intelligence. The essence of "humanized" functions such as "your favorite software" is derived from this kind of statistical logical thinking, and when it comes to its limits, it is natural to reach the level of "real" artificial intelligence.

In the era of binary, there was a lot of discussion about whether "artificial intelligence" would really be "intelligent......

Now, Harry is using ternary to make up the same kind of algorithm......

Alice uses this algorithm to do all kinds of calculations again and again. The dazzling array of high-math equations flashed across the screen without interruption, and the people around them watched silently, barely keeping up with Alice's speed, but not preventing them from coming to a common conclusion.

Harry looks amazing.

The boss is even more awesome.

"It's not easy, man."

Finally, after a full half hour, Alice let go of the keyboard and said in surprise: "The logical structure is perfect, exactly the same as the genetic algorithm in the binary state, you have successfully broken the limitations of language!" ”

This sentence is very subtle. Breaking the language is something that all programmers have been working on, and Alice doesn't say how good Harry's algorithm is, but simply shows that he has succeeded in reproducing binaries of the same grade in ternary.

Harry also immediately figured out the taste, but of course he didn't have any discouraged thoughts, but thought of the other side.

"Heredity means the ability to learn, and the biggest difference between ternary and binary is that its way of thinking is closer to that of humans. Boss, if we continue to study this algorithm, will we really be able to build intelligent computers? ”

That's the question......

That's a problem indeed.

The ideas and concerns about intelligent computers and intelligent robots did not appear until "Terminator II" and "The Matrix", and the android "Bishop" of "Alien" is not old enough.

"I, Robot", a collection of science fiction short stories by American writer Isaac Asimov published in 1950, contains nine short stories, most of which were originally published in the American magazine "Super Science Fiction" and "Amazing Science Fiction" magazine between 1940 and 1950. The short stories in the book are independent but share a common theme: exploring the moral issues between humans and robots. Combined, these stories create the fictional history of Asimov's robotic Haohan.

In fact, Alice had met Asimov himself at a party a few years earlier......

"Give me a copy of your algorithm.

She said to Harry, "Then I'll go to the third floor." ”
