The defense and attack of the twilight monster has been increased by three times compared with that of the main world. Please eat carefully. It is suggested that you wear iron jacket or better equipment to prevent being attacked for seconds. You can choose iron axe or iron sword as weapons. The former has high attack enrance and the latter has low enrance. On the contrary, there is no iron ore in the twilight stratum. Before entering, please bring your own iron ore to make iron axe, iron sword, iron bow, etc, Because there are many kinds of canyons in the twilight, you also need to bring stepping stones to cross the road. Another reason is that many people like to dig vertical tunnels. If they accidentally fall down, they can put them up if they are not dead. If possible, they can take conveyor stones to help transport them to the nearby sky Island portal. They can be purchased or they can open a trumpet brush, I really didn't come back from losing all my experience above level 7< br />
In order to enter the artificial intelligence instry, we must first have a certain mathematical foundation, because artificial intelligence is different from app development, web development, game development and other traditional internet jobs. We can check the API call function or beautify the interface every day
Artificial intelligence is evolved from "approximation theory" in mathematics. At the beginning, most of the methods used in artificial intelligence are used by mathematicians to approximate some nonlinear functions which are difficult to express. Later, with the improvement of computer performance, computer workers and statisticians began to try to use this set of "approximation theory" to solve some classification problems. Graally developed into the current situation of artificial intelligence2. At the beginning of the development of artificial intelligence instry, there are few API functions available, so it is necessary to write your own algorithm. For the engineers who want to master the knowledge of artificial intelligence, mathematics is an unavoidable obstacle
Artificial intelligence is a big concept. Nowadays, the so-called AI applications of many companies are still in the primary stage, such as information (data) classification, filtering, pattern recognition and so on. Many languages have formed code packages, open source code and so on, More is the need for the support of big data, constantly optimize the algorithm4. Now some popular intelligent devices, smart home, I don't think it is artificial intelligence, but more is the application of various sensors and program rules. Maybe this kind of instry will be closer to life and more market. The prospect is very promising. However, just like making software, it's not sure that a good software proct can be made with good technology. It's necessary to have a deep understanding of user needs and pay attention to user experience. In your background, I think it may be better to develop in this direction
The world's first general-purpose computer "ENIAC" was born in the University of Pennsylvania on February 14, 1946. The inventors are American mokley and Eckert
the first computer was a giant, which used 18000 electron tubes, covered an area of 170 square meters, weighed 30 tons, consumed about 150 kW of power, and could perform 5000 operations per second, which was insignificant now, but it was unprecedented at that time. ENIAC is also known as electron tube computer, which is the first generation of computer. Electron tube computer because of the use of electron tube volume, power consumption, easy to heat, so the working time can not be too long
Extended data:ENIAC was born ring World War II. It was initially used as a tool to assist artillery to calculate the trajectory of artillery shells. It was manufactured one year before the Allied forces landed in Western Europe, but it was not completed until the cease-fire in 1945. In the early days of the cold war, the military discovered a large number of uses of ENIAC. Its 17468 vacuum tubes were used to test the feasibility of the early design of hydrogen bombs. The computer could execute 5000 instructions per second, which was 1000 times faster than an electric computer at that time

American supercomputer & lt; Vertex & quot; Once again, China continues to expand its leading position in quantity. According to the list, there are 228 supercomputers on the list in China, ranking the first in terms of the number of supercomputers, an increase of 9 compared with the list released half a year ago. The United States ranked second with 117, followed by Japan, France and Germany
This is the second time that the U.S. Department of energy has decided to spend a huge sum of money to develop the 10 billion supercomputer system. Its first 10 billion supercomputer A21 is currently in the development stage and will be deployed in Argonne National Laboratory and will be put into use in 2021. In April last year, two supercomputers were planned to be deployed in Oak Ridge National Laboratory and Lawrence middot in 2022 and 2023; Livermore National Laboratory to meet the needs of the advanced scientific computing research project of the science office of the Ministry of energy and the advanced simulation and computing project of the national nuclear safety administration However, China has launched the e-level computer R & D program; Tianhe-3 & quot; It's part of the plan. It is reported that the whole plan is divided into two phases. The first phase is to study & lt; Key technologies of E-class computer Three E-class prototypes were developed; The task of the second phase is to develop E-class computeraccording to the news from the National Supercomputing Center in Tianjin, China's self-developed new generation of 10 billion secondary supercomputers & lt; Tianhe-3 & quot; The E-Class prototype has been developed and deployed, and has successfully passed the sub project acceptance. Not only that, & lt; Tianhe-3 & quot; In addition, three kinds of domestic independent high-performance computing and communication chips are used, namely & lt; Maichuang & quot; Multi core processor, high speed interconnection controller and interconnection interface controller. In addition, it includes four types of computing, storage and service nodes, hardware subsystems such as computing processing, high-speed interconnection, parallel storage and service processing, and software subsystems such as system operation, parallel development, application support and integrated management, all of which are independently designed in China
according to the plan, next year, China will build a completely independent & lt; Tianhe-3 & quot; E-class supercomputer, computing power compared with & lt; Tianhe-1 & quot; It can be increased 200 times
Meng Xiangfei, director of application research and Development Department of National Supercomputing Center in Tianjin, said that they will rely on & lt; Tianhe-3 & quot; Build a high-performance computing service platform with deep integration of supercomputing and cloud computing, big data and artificial intelligence, which can be used for a series of super large-scale computing and simulation, such as long-term high-resolution climate and weather forecast, large-scale Aerospace numerical wind tunnel, brain science and genetic engineering
at this time, the camera is the character's perspective. I must give the boss a wave of purple sticky poison bullets, which will add a lot of vertigo. At this time, I will take stimulants. I don't know if too many stimulants will lose water like ginkgo, However, we should be able to do so at this time.
when we all ride the Tyrannosaurus Rex, we can walk and try not to go to the purple poisonous fog. Vertigo is added to Tyrannosaurus Rex. When the boss doesn't attack, it's the card owner, and then you have to pay attention to the sand bug, because it will repel the Tyrannosaurus Rex, so you keep inserting it into the boss. If you don't have the card owner, you have to repeat the above steps. When you see the stone man, it means that you are going to succeed. Don't worry about the stone man's biting. After playing the boss, you must dismount the dragon and pull the Tyrannosaurus Rex away from the corpse of the boss. There is a high probability that if you don't dismount the dragon, the Tyrannosaurus Rex will die.
the lion scorpion boss Tyrannosaurus rex has a 700 attack on 6, which is relatively simple.
next, a gorilla is very simple. Prepare a Tyrannosaurus Rex, a Velociraptor, or you are confident that you can reach the boss with high speed, Before going in, the overlord's head was pasted with 400c4. The characters put on their sweaters. It was really cold inside., The boss is responsible for leading the spider to the Tyrannosaurus Rex. The unlocked person rides on the Tyrannosaurus Rex, but the Tyrannosaurus Rex rider doesn't need the remote control. He thinks that you are likely to be lost by the boss in seconds, so he can ask another person to detonate it. It's better not to look at the picture when it explodes, because it's bloody to turn the camera (in fact, the memory will explode, and it's easy to drop the line), It's OK for this main team to cooperate well, and it's also important to consider the server delay, so that spiders can damage Tyrannosaurus Rex, and it's not too late to blow it up.
then let's talk about the next spider boss. It's very easy for the boss to get stuck. Tyrannosaurus Rex can go without adding blood. More than 10 people and more than 10 Tyrannosaurus Rex can kill it if they attack 800 or so, I'm playing PVE. If I find that it's a little bit worse than blood, if I can't get through it, I'll take the RPG tribe to fight against spiders in advance. I think the PVE mechanism won't hit things that are not with my own tribe, so I don't worry. Only one or two can get down, not too much, or the boss will be embarrassed if he doesn't have a card owner.
the difficult star above has been changed, and the amount of blood has increased. It needs 500 c4sorry
and there are still many left. After all, the fire dragon who is easy to roll over is the most difficult to fight, because spiders can pass as long as you have enough T-Rex attack, Gorilla as long as the normal server does not delay very stable, but the fire dragon is not the same, fireball seconds kill the rider, extremely difficult to card the owner's position. And it's a great test of the team's execution. You should obey the command.
fire breathing dragon, first of all, you can wear lucky clothes, about seven people can pass. Of course, you should cooperate with Tyrannosaurus Rex and whole blood. You think it's easy to have no card owner, and you need blood. When you land on the card next time, the magma of the boss field can step on, and there is not a lot of blood. After you go in, the dragon will quickly pull away, The first person who goes in can hold the hatred. Anyway, you can't stop running before landing. When a person is sprayed on the fireball, you can GG. When it hits the ground and gets stuck, the T-Rex's head up is to pull up the angle of view. Don't bite before it doesn't have to bite. If it can't fly off at the next take-off, it's OK. Don't move after the card owner, because you don't know who is the T-Rex card owner
