random number generator no repeats

Recent lab projects need to implement a simulated file access sequence that requires the number of data requests per unit time to be in accordance with the Poisson distribution, while the time interval of two requests meets the exponential distribution. There is no way to re-pick up the probability that has been lost a long knowledge. Then there is the implementation of the random

Kernel pseudo-random number generator Information Entropy Vulnerability-Linux general technology-Linux programming and kernel information. The following is a detailed description. Affected Systems: Linux kernel Linux kernel Unaffected system: Linux kernel 2.6.21.4 Linux kernel 2.6.000013 Description: Bugtraq id: 24390 CVE (CAN) ID: CVE-2007-2453 Linu

For more information, see numerical recipes in C ++ 2/e p.292 ~ P.294 and Simulation Modeling and Analysis 3/e p.465 ~ P.466. Box and Muller provided an algorithm for generating a normally distributed random variable from a uniformly distributed random variable in 1958. Where U1 and U2 are random variables with a uniform distribution on the intervals (0, 1), they

in 0 and mod-1 of all numbers, then it will evenly generate pseudo-random numbers with each mod iteration. If the step= 15 and mod = -, the function generates series 0, the,Ten,5(or any other repeating series if the initial seed is not 0). This is a poor step and mod selection because no initial seed will be generated from 0 and mod-1 of all numbers. Your program will determine whether the selection of step and mod will generate a uniform distributio

A recent project reminds me of a very simple way to generate a pseudo-random number to create a raindrop's behavior. I found that if we had a randomly initialized unsigned 32-bit seed n could loop through a pseudo-random number (C) using only 14-character multiplication tables: n*=0x9e3779b1; Each time you apply this
