原创 VMware或virtualbox虚拟机虚拟网卡缺失解决办法

通过Xshell连接虚拟机,若出现设置正确(IP地址以及用户名、密码都对),但连不上,可通过查看控制面板的网络连接,一般VMware和Virtual Box安装后都有虚拟网卡存在,但安装完或可能安装后因某些原因导致虚拟网卡缺失,会引起Xshell类似的远程客户端连不上虚拟机问题。例如VMware缺少VMware Network Adapter VMnet1和VMware Network Adapter VMnet8。

Artificial intelligence- a modern approach (2ed,PH,2003)(T)(1112s)

最经典的人工智能教材 Artificial Intelligence A Modern Approach Second Edition Stuart J. Russell and Peter Norvig Contributing writers: John F. Canny Douglas D. Edwards Jitendra M. Malik Sebastian T h n Pearson Education, Artificial Intelligence (AI) is a big field, and this is a big book. We have tried to explore the full breadth of the field, which encompasses logic, probability, and continuous mathematics; perception, reasoning, learning, and action; and everything from rr~icroelectror~dice vices to robotic planetary explorers. The book is also big because we go into some depth in presenting results, although we strive to cover only the most central ideas in the main part of each chapter. Pointers are given to further results in the bibliographical notes at the end of each chapter. The subtitle of this book is "A Modern Approach." The intended meaning of this rather empty phrase is that we have tried to synthesize what is now known into a common framework, rather than trying to explain each subfield of A1 in its own historical context. We apologize to those whose subfields are, as a result, less recognizable than they might otherwiise have been. The main unifying theme is the idea of an intelligent agent. We define A1 as the study of agents that receive percepts from the environment and perform actions. Each such agent implements a function that maps percept sequences to actions, and we cover different ways to represent these functions, such as production systems, reactive agents, real-time cortditional planners, neural networks, and decision-theoretic systems. We explain the role of learning as extending the reach of the designer into unknown environments, and we show how that role constrains agent design, favoring explicit knowledge representation and reasoning. We treat robotics and vision not as independently defined problems, but as occurring in the service of achieving goals. We stress the importance of the task environment in determining the appropriate agent design. Our primary aim is to convey the ideas that have emerged over the past fifty years of A1 research and the past two millenia of related work. We have tried to avoid excessive formality in the presentation of these ideas while retaining precision. Wherever appropriate, we have included pseudocode algorithms to make the ideas concrete; our pseudocode is described briefly in Appendix B. Implementations in several programming languages are available on the book's Web site, aima.cs.berkeley.edu. This book is primarily intended for use in an undergraduate course or course sequence. It can also be used in a graduate-level course (perhaps with the addition of some of the primary sources suggested in the bibliographical notes). Because of its comprehensive coverage and large number of detailed algorithms, it is useful as a primary reference volume for A1 graduate students and professionals wishing to branch out beyond their own subfield. The only prerequisite is familiarity with basic concepts of computer science (algorithms, data structures, complexity) at a sophomore level. Freshman calculus is useful for understanding neural networks and statistical learning in detail. Some of the required mathematical background is supplied in Appendix A.

C++ The Complete Reference, 4th Edition - Copy

If there is one language that defines modern programming, it is C++. Its syntax, style, and philosophy have set the standard by which all other languages are judged. Furthermore, C++ is the universal language of programming. When an algorithm or technique is described, it is usually done so using the C++ syntax. The long-term success of C++ has also left a lasting impression on computer language development. For example, both Java and C# are descended from C++. Frankly, to be a professional programmer implies proficiency in C++. It is the one language that no programmer can afford to ignore. This is the fourth edition of C++: The Complete Reference. It fully describes and demonstrates the keywords, syntax, functions, classes, and features that define the C++ language. More specifically, this book fully describes Standard C++. This is the version of C++ defined by the ANSI/ISO Standard for C++ and it is the version of C++ that is supported by all major compilers, including Microsoft’s Visual C++ and Borland’s C++ Builder. Thus, the information in this book is applicable to all modern programming environments. In the time that has passed since the previous edition of this book, there have been no changes to the C++ language. There have, however, been big changes to the computing environment. For example, a new standard for C, called C99, was created, Java became the dominant language for Web programming, the .NET Framework was C++-specific features. Part Two discusses in detail the features that move beyond the C foundation and define the C++ language These include its object-oriented features such as classes, constructors, destructors, RTTI, and templates. Thus, Part Two covers those constructs that “make C++, C++.” Part Three describes the standard function library and Part Four examines the standard class library, including the STL (Standard Template Library). Part Five shows two practical examples of applying C++ and object-oriented programming.
