1. Question
Given a random number generator, this generator can generate a random number ranging from 1 to 5 () evenly. How can we use this generator to generate a
Method One: Generate two (1,5) random number, this is a total of 25 cases, note that the two numbers are in order, from the 25 cases, take the first 21, each three kinds of representative (1,7) A number, if you take the case of the 21, discard the re-fetch.Method Two: Generate three (1,5) random numbers, representing a

The number of on-demand computers has important applications in many fields, such as Monte Carlo simulation, cryptography, and network security. The random number quality is directly related to the reliability and security of the network security system, and to the reliability of the Monte Carlo simulation results. Since the birth of the computer, it has been a l
RandomThe random class in Java generates a pseudo-random number, uses the seed of 48-bit, and then calls a linear congruential formula linear congruence equation (Donald Knuth's programming Art of 3.2.1)If two random instances use the same seed, and the same function is called, then the generated sequence is the sameYo

In the previous blog, we learned about the real random number generator based on physical phenomena, however, the real random number generation is slow, for the actual computation needs, the random
We often need to randomly generate a group of non-repeated questions when performing an exam system that can automatically generate the exam. net Framework provides a class System dedicated to generating random numbers. random.

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
