/ * At the 7th Council of China's Computer Society held this year (2000), the academician Wang became a special academic report. The topic of his report is: "Ask about my country's computer development 12 A problem. Wang's governance believes that the reason why the computer can develop rapidly, and the reason is that there are many improvements, so he is proposed to ask some questions that have not been discovered in the study, ask other experts (contained in April 2000) 26th Guangming Daily). * / (Author's custom reference "/ *", "* /", etc.)
The author is not shallow, in order to learn, exchange the attitude towards you, talk about some of my opinions in the form of a question and answer, hoping to play the effect of bricking jade. The author's level is limited, and the misfortune is inevitable, improperly, please criticize. At the same time, welcome to my homepage: http://yjx_online.go.nease.net
/ * One, some people think: From the calculated theory of the map, the three premise of "calculated": the problem must be formified; there must be an algorithm; there must be reasonable complexity. Excuse me: Do we try to break through and maybe (or partially) breakthrough? Still can only be innovative under this premise? * /
A: Do not advocate these three premise, it is recommended to innovate under these three premise. The model of the map is similar to the following modifications: [1] has a record strip with unlimited plurality of memory cells, and the content of each memory cell is limited, usually represented by binary "O" and "1". Storage unit Partitioning organization; [2] Unlimited multiple readers with limited internal states, each read writing is responsible for a memory block. The read writing should be left or right on the record tape or not moving on the record tape. In operation, the map is read according to its internal state and the content of the current storage unit, and the contents of the internal state and the storage unit are changed according to the established rules. And determine the direction of movement of the writing head next step. [3] There is a function that can read the status of other read-write heads through this function. For more than half a century, mathematicians, computer scientists have proposed a variety of calculation models proved to be the same as the same map. This may be because they have the hardware level and network performance that have never been like today. Today, the network transmission bottleneck will gradually be broken, and the grid calculation will become the inevitability of computer history. It is appropriate to make it suitable for new computing modes. The above model may be called "grid map spirit". Improve the grid map forever model, establish a new calculated theory, is not a good job in the first day. And it is limited to the space, and will not be described again. Wang University is in the 148th academic seminar of Xiangshan Science Conference to extend the premise of "calculated" as: a set of rules, rules can be executed, and the execution can be terminated. This kind of submit is a good innovation.
/ * II, some people think: people think and deal with the cognitive process of the problem are parallel, open, multi-dimensional, summoned; and the processing of computer solving problems is a limited long sequence of limited symbols, according to prior computing The procedure is a poor transform for this sequence to get a new set of symbols. I would like to ask: Is the inconsistency of these two processes is the main reason for the formation of people and computers? Try to make the two principal efforts of both the future computer technology and artificial intelligence technology? * /
A: "For the finite length sequence of limited number symbols, according to the prior program, this sequence is a poor transform, thereby giving a new set of symbols." - Such calculation mode is still in the framework of the map within. If the computer extends as a human brain, it is in terms of calculation mode, storage mode, and information transmission mode have a manifest that is unable to match. There are many cognitive processes for human thinking and processing issues, and there are currently highlights that have not been reached far. The advantage of continuous absorption of human thinking is that it is inevitable in computer technology and artificial intelligence technology development processes.
/ * Third, some people believe that the role of the software is to translate people's cognitive processes into a process that can be accepted by a particular computer. With the development of computer technology, the key technology of software has been encoded in the 1960s, the design of the 1970s, the demand of the 1980s, developed into the "demand engineering" era of the 1990s. Object-oriented, soft components, distribution processing, network computing, visualization, concurrent engineering, etc. are all products of the "demand engineering" era. I would like to ask: Is the ultimate goal of "demand project" provide users with "a package of solutions"? How to determine the development trend of software technology and software products in the next century? * /
A: With the universal application of the computer, it is possible to make the product's multi-variety small batch industrial production in the industrial field. Software products are more suitable for multi-varieties of small sales than the general industrial products due to their specialty. The demand project refers to the application that has proven effective technologies, methods to analyze, determine customer needs, help analyst understanding questions and defines a discipline of all external features of the target system. As a part of the multi-variety of software products, the demand project is a link in the production process of software products, and the ultimate goal is to produce software product services for market-oriented, "a package of solutions" is only part of it. The development of object-oriented methods may result in humanity and mathematics of soft components. Thus affecting and promoting the research of "demand engineering". Mathematical trends in software engineering methods, just like Kano map in digital circuit logic design, there may be similar methods in software engineering.
/ * Fourth, some people believe that the invention of digital computers is the largest scientific and technological achievements in the 20th century, which has a profound impact on humans. Digital survival is the development trend of the 21st century, which will fully and profoundly improve the quality of life of humans. I would like to ask: Plug and play, optimization, adaptive, immersion, human machine harmony, etc. have all the advantages of simulation. How to judge the digital to a digital to a few-level? Whether in the future, will BeinganAlog? What are we prepared for this? / *
A: ()
/ * 5. Some people think that the past communications is connected, and the biggest advantage of the Internet is to non-connection; the three network integration of telecommunications network, TV network, computer network is the development trend of the early 21st century; achieve full-light The transmission speed will be greatly improved. Excuse me: What is the future network development direction? What is the main attack direction in addition to the full fusion of a connection and non-connection-oriented characteristics? What support technology do they need? What a big impact is there? What application caused? Drive which industries? * /
A: ()
/ * Six, some people believe that in order to develop my country's information industry, my country must have the strength of developing high-performance chips, but from high performance, universal CPU is not the best way, and should be long-term, from SYSTEM ON CHIP starts. Excuse me: What should my country should start? What facilities and support technologies should be given priority? How to ensure the benign circulation of research, application and industries? * /
A: ()
/ * Seven, some people believe that the computer architecture should be a need for network calculation. Currently, "simple client" and "powerful server" should be developed. Client should gradually implement Smart, while Server should follow SUMA Guidelines (ie Scalability, USAbility, Scalable, easy to use, manageable, available). In the future, Client will be a P3C or a compunicator, while Server will eventually develop into Virtual Server ENVIRONMENT. Excuse me: Is this predicted accurate? If it is basically accurate, this client and server will use the architecture and basic software? What will be measuring the indicators of their performance and disadvantage? * / A: ()
/ * 8. Some people think that we must develop computer systems for the Chinese, which should include "Chinese Good" host, software, input / output, network system, and development tools and environments. Excuse me: How is it "the" Chinese "computer? Where is the essence of a general computer? In order to develop this computer, what basic theories and key technologies should be given priority? * /
A: Our Chinese ancestral invention abacus is the earliest "computer". If the abacus beads are mixed, then it cannot be used as a calculator. On the abetment, the next two states provide calculations, storage functions. Therefore, the algorithm of the abacus is based on the mechanical logic gate based on binary basis. The computer we use is also based on the binary basis, which is "medium-secondary"; use English letters on the keyboard, which can be described as "Western learning".
/ * Nine, some people believe that bottlenecks that hinder my country's information technology development and information construction value-added benefits (social benefits and economic benefits) are despise the construction of information resource construction, which is the most serious reflection of "hard and soft". I would like to ask: Where is the crux of the desirable information resource construction? Is it awareness, management, or technical issues? In the construction of information resources, people look forward to the efficiency of the knowledge value, which should check which key technologies should you? How to analyze the source of profit in the future information industry? * /
A: ()
/ * 10, some people think: information security is the most urgent problem, has huge industrial prospects. To this end, we should develop its own CPU, operating system, database, private network, network software, strictly implement the login system, identity authentication, password ... Excuse me: What is the key to information security under the premise of full-time information sharing? Order? What is the information security technology that should be greatly broken? * /
A: ()
/ * Eleven, some people believe that the current development of computer technology has developed rapidly, new concepts, new technologies, new products and new products. In order to make students can adapt faster after graduation, the university is busy with the new technologies to students. So the textbook became the "Product Manual", and the tutor is "selling", "the scholar is" busy with sharpening, very little slaughter ". Excuse me: How should I improve the teaching status of current computer science? * /
A: ()
/ * Twelve, some people think: When solving the above problems, consider the following premise: the results of the application software that must be able to inherit the previous accumulation; must follow the internationally developed or popular standards; expectation to produce an economy during a certain period of time Or social benefits. Excuse me: These prerequisites are to limit innovation or "inheritance development" must be followed by objective laws? How should we handle this contradiction? * /
