This book was released on 2018 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: Random Number Generators, Principles and Practices has been written for programmers, hardware engineers, and sophisticated hobbyists interested in understanding random numbers generators and gaining the tools necessary to work with random number generators with confidence and knowledge. Using an approach that employs clear diagrams and running code examples rather than excessive mathematics, random number related topics such as entropy estimation, entropy extraction, entropy sources, PRNGs, randomness testing, distribution generation, and many others are exposed and demystified. If you have ever Wondered how to test if data is really random Needed to measure the randomness of data in real time as it is generated Wondered how to get randomness into your programs Wondered whether or not a random number generator is trustworthy Wanted to be able to choose between random number generator solutions Needed to turn uniform random data into a different distribution Needed to ensure the random numbers from your computer will work for your cryptographic application Wanted to combine more than one random number generator to increase reliability or security Wanted to get random numbers in a floating point format Needed to verify that a random number generator meets the requirements of a published standard like SP800-90 or AIS 31 Needed to choose between an LCG, PCG or XorShift algorithm Then this might be the book for you.

Available in PDF, EPUB and Kindle. Book excerpt: This book covers pseudorandom number generation algorithms, evaluation techniques, and offers practical advice and code examples. Random Numbers and Computers is an essential introduction or refresher on pseudorandom numbers in computer science. The first comprehensive book on the topic, readers are provided with a practical introduction to the techniques of pseudorandom number generation, including how the algorithms work and how to test the output to decide if it is suitable for a particular purpose. Practical applications are demonstrated with hands-on presentation and descriptions that readers can apply directly to their own work. Examples are in C and Python and given with an emphasis on understanding the algorithms to the point of practical application. The examples are meant to be implemented, experimented with and improved/adapted by the reader.

Download or read book Some efficient random number generators for micro computers written by Arne Thesen and published by . This book was released on 1983 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: The relatively slow speed and small word size of the current crop of micro-computers causes the efficient production of pseudo-random numbers on these machines to be considerably more difficult than on larger computers. As a consequence, some micro-computer-based algorithms are excessivly time consuming, while other algorithms trade off speed against 'randomness'. To alleviate this problem we present in this paper several families of pseudo random number generators explicitly designed for use on micro-computer environment, others are new or lesser known algorihtms designed to overcome some of the restrictions intrinsic to the micro-computer's 8 bit environment. For each generator the basic algorithm is discussed and a Pascal implementation is presented. Values of coefficients leading to pseudo random number streams with good statistical properties are recommended and an empirical evaluation of the computational efficiency of the Pascal procedures is offered.

Download or read book Random Number Generators on Computers written by Naoya Nakazawa and published by . This book was released on 2024-11-28 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph proves that any finite random number sequence is represented by the multiplicative congruential (MC) way. It also shows that an MC random number generator (d, z) formed by the modulus d and the multiplier z should be selected by new regular simplex criteria to give random numbers an excellent disguise of independence. The new criteria prove further that excellent subgenerators (d1, z1) and (d2, z2) with coprime odd submoduli d1 and d2 form an excellent combined generator (d = d1d2, z) with high probability by Sunzi's theorem of the 5th-6th centuries (China), contrasting the fact that such combinations could never be found with MC subgenerators selected in the 20th-century criteria. Further, a combined MC generator (d = d1d2, z) of new criteria readily realizes periods of 252 or larger, requiring only fast double-precision arithmetic by powerful Sunzi's theorem. We also obtain MC random numbers distributed on spatial lattices, say two-dimensional 4000 by 4000 lattices which may be tori, with little pair correlations of random numbers across the nearest neighbors. Thus, we evade the problems raised by Ferrenberg, Landau, and Wong.

This book was released on 1982 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: The RANDOM computer program evaluates the usefulness of pseudo-uniform random number generators. RANDOM was written in FORTRAN IV for the CDC 6700 computer system at the Naval Surface Weapons Center, Dahlgren. This program can also be used to evaluate candidate pseudo-uniform random number generators designed for use on any other computer system. RANDOM subjects the candidate generator to 11 different statistical tests designed to detect departures from randomness. These tests serve as useful tolls for determining the adequacy of a candidate generator. (Author).
