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 bits, where 1 and 2 are mapped to 0, 3 skipped, 4 and 5 are mapped to 1. This produces a

This function is required to write a Rand3 function (In addition, can no longer use

Random Number, random number generator Math. random () generates a random number of the double type in the range of [0, 1. Thread security: multi-threaded environments can be called. (Int) (Math. random () * n) generates a

Introduction to linear homogeneous random number generator: The old LCG (linear congruential generator) represents the best and simplest pseudo-random number generator algorithm. The main reason is that it is easy to understand, easy to implement, and fast. The LCG algorith

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 sameYou can also call Math.random () to generate a

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 number in the computer is generated by the program algorithm, that is, some formula function, but for the same

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 long-term topic to seek to use the computer to produce high-quality

Header file Now I want to generate a random number, I use the following program:#include The problem comes, although we produce a random number, but no matter how many times I run the above program (recompile, run, also 41), it produces a definite number. That is, 41, as follows:What is this for?The answer is that to get a random number, we need to enter a seed (
