The Goddess Shines on America

One second to remember 【】, to provide you with wonderful novel reading.

Now that the employees below have made such fresh achievements, Alice certainly can't leave, but she has to go upstairs to hang up a few calls before studying Harry's ternary genetic algorithm.

The first is for the family. James is taking everyone to drive in Scotland, saying that he wants to see William Wallace's deeds back then. Although he was not small, how could he fit a big brother and big cell phone in a car, and the call was quickly connected.

As for the related content, naturally I just discovered a breakthrough topic, and may have to be busy for several days and nights like other programmers. Therefore, after arriving at the hotel, I can save a few days or two weeks for liaison with my eldest daughter. Don't contribute to British Telecom's phone bills. People earn enough, even though Alice has thrown away tens of millions of shares.

Then a phone call was put to Mai Mi. Let the eldest girl of the family travel thousands of miles across the Atlantic Ocean, of course, she can't just stay in Exeter for a day or two and leave.

In the past few days, in addition to messing with the mercenary security guards in the research institute, Mai Mi was mainly experimenting with the power of Alice's new gunpowder. Various environments, various dosages, and various explosive power mixed with other gunpowder are all things that interest her very much. Not to mention when Alice handed the "deteriorated version" of Super Gunpowder to Lockheed, no one stipulated that she could not do the experiment on her own.

"Hey honey, you..."

As soon as the phone was connected, I heard an explosion roar, and then it was Mai Mi: "Alice, I just thought of a problem recently. Although crystal explosives are convenient to carry, but the quantity is not suitable for grasping. When we mass produce in the future, will it still be Should we cut and polish different specifications in advance?"

Hey, I actually thought of such a layer.

Alice thinks about it: "You mean the field of special operations? Considering the explosive power... we can cut them into a small fingernail-sized lens, which is equivalent to a grenade, and then use explosives such as thunderbolt. Mix it with plastic..."

"Aili, I mean, is the explosive crystal size specified during production?"

Even if it’s not for joining the army after graduation, Mai Mi considered it from the perspective of a professional soldier. Alice couldn’t help but feel relieved and laughed, “Of course it’s a specific arrangement. The colloid solidifies and is called crystallization. Just prepare. Isn’t it just a good model? The size of a fingernail, the size of a little fingertip, the size of a slab, the size of a pizza, aren’t they all casual?"

It is really interesting to think about it. The crystal-like new gunpowder with 20 times the power of TNT is simply innately prepared for special operations and terrorist attacks. Alice has realized that the main components of the new explosive are only nitrogen, oxygen and traces of deuterium and carbon, which cannot be detected by police dogs and existing scanners.

So it's no wonder that Mai Mi thinks of related fields, but the terrorist attack is not rampant at this time, otherwise there will be a lot of worries.

"So... OK, then Ai Li, did you hang up the phone?"

Of course, I was claiming that I was going to retreat and meditate for a week, let me know, hang up, and then go back to the fourth floor of the institute.

"It's really a shame that you can use the ternary system to make the research algorithm." Sitting on Harry's chair, Alice said to the people around him: "Everyone sees it, when you are still trying to write calculations using ternary codes. Harry had already developed the genetic algorithm when developing software!"

Harry, of course, looked humble: "It's just a fluke. I just wanted to give it a try. I didn't expect to succeed at all. And the boss, you are really awesome, you can see what I'm writing at a glance."

"Harry has a girlfriend!" The tall and thin John smiled on the side: "You two must be getting married? How else would you think of genetics?"

"That's it! Darwin's theory of evolution! Harry wants to be a father!"

Of course the people around are cheering happily, not to mention that this algorithm is not their own achievement, but who can not be happy to prove a breakthrough in the field?

Practice has proved that using ternary methods to write programs is really very different from the binary era. Although it is "just" a genetic algorithm, its meaning is not worse than the birth of the algorithm itself in this ternary wasteland reclamation period.

You know, things like algorithms are really different from simply doing math problems. It tests not only the programmer's basic knowledge, but also his way of thinking. After all, any algorithm is, in the final analysis, to solve a certain need.

This is why, when companies such as Google and Microsoft have completely emerged, the interview questions are always so weird-the test is not the programming ability, but the way of thinking.

Don't be an outsider, Alice can immediately think of a film and television example about the application of algorithms.

In the American TV series "I Am a Zombie", the zombies' hair color and skin tone will become very pale, and while they love to eat human brains, they also have an irresistible love for chili sauce-other than that, everything they eat has the same taste as wax. .

Therefore, the "sports drink" company that accidentally created these zombies wrote an algorithm to identify how many zombies there are in Seattle—by tracking credit card consumption records, that is, hair dyeing, sunbathing, hot sauce products, and statistics. The number and frequency of their purchases.

So, programming itself is a very easy task. What people really care about is the function of the software made by programming. It is the biggest test for all programmers to meet the various needs of users with the smallest size, the strongest stability, and the highest execution efficiency.

So next, it was time for Alice to personally check that Harry's genetic algorithm written in ternary system was different from the old binary system.

In this process, both Alice and other bystanders have to face a very interesting problem-the conversion of the thinking process.

Just like all people who are not yet proficient in a foreign language, they have to use their native language when reading a foreign language.

Looking at Harry's ternary code, anyone must convert it to binary in order to gain a higher understanding, even Harry himself is no exception.

The genetic algorithm first converts the operand, that is, the variable into a series of strings, and performs evolutionary operations on the population. Here, it needs to prepare some initial population data representing the starting search point. Then, it will use fitness calculation to evaluate the pros and cons of each individual based on the fitness of the individual, thereby determining the size of their genetic opportunities. Finally, through selection and calculation, the individuals with higher fitness in the current population are inherited to the next generation population according to a certain rule or model.

In this process, as stated in the basic principles of Darwin's theory of evolution, the algorithm also needs to take into account the "new birth" and "mutation" issues. That is, the crossover operation, with a certain probability, exchanges some "chromosomes" between two individuals to realize the birth of new data. At the same time, mutation operation is used to change a certain individual or certain “elements” according to a certain small probability. It is also an operation method for generating new individuals.

It is this series of calculation principles that enable genetic algorithms to be widely used in the field of artificial intelligence. The essence of "humanized" functions such as "your commonly used software" is derived from this logical thinking based on statistics. At its limit, it will naturally reach the level of "real" artificial intelligence.

In the age of binary, people are discussing whether "artificial intelligence" will really have "intelligence"...

Now, Harry relies on the ternary system to compile the same kind of algorithm...

Alice uses this algorithm again and again to do all kinds of calculations. The various high-number solving equations are dazzling, flashing on the screen non-intermittently, and people around them watching silently. Although almost all of them can't keep up with Alice's speed, they do not prevent them from reaching a common conclusion.

Harry looked amazing.

The boss is even better.

"It's not easy, buddy."

Finally, after half an hour, Alice released the keyboard and said in surprise: "The logical structure is perfect, exactly the same as the genetic algorithm in the binary state. You successfully broke the language limit!"

This sentence is very subtle. Breaking language limitations is an effort that all programmers have been doing. Alice did not say how excellent Harry’s algorithm is, but simply showed that he successfully reproduced the same grade of binary products with ternary systems. .

Harry also figured it out right away, but of course he didn't have any discouraged thoughts, but thought of another aspect.

"Inheritance means learning ability, and the biggest difference between ternary system and binary system is that its way of thinking is closer to that of humans. Boss, if we continue to study this algorithm, UU Reading www.uukanshu.com is Isn't it really possible to make a smart computer?"

This question...

It is indeed a problem.

The ideas and concerns about smart computers and smart robots did not appear until "Terminator II" and "The Matrix", and the bionic "bishop" of "Alien" is not old enough.

"I, Robot", a collection of science fiction short stories published by American writer Isaac Asimov in 1950, contains 9 short stories, most of which were originally published in the American "Super Science Fiction" magazine and "Marvel Science Fiction" magazine. The short stories in the book are independent, but share a common theme, which is to explore the moral issues between humans and robots. The combination of these stories created Asimov's vast fictional history of robots.

In fact, Alice met Asimov herself at a party several years ago...

"Copy me your algorithm.

She said to Harry: "Then I will go to the third floor." Mobile users, please browse and read for a better reading experience.
