mersenne twister random number generator

The random numbers we speak of actually imply pseudo random numbers. Many friends may think of the C language rand (), unfortunately, this function produces random number of randomness is very poor, and the speed is very slow, I believe almost not

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

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

PHP pseudo random number and true random number detailed, pseudo random number detailed The first thing to declare is that the computer does not produce an absolute random number, and the computer can only produce "pseudo-random numbers". In fact,

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 algorithm is based on the formula: X (n +

The first thing to declare is that the computer does not produce an absolutely random random number, and the computer can only produce "pseudorandom numbers". In fact, the absolute random random number is only an ideal random number, even if the
