In computer science, multiply-with-carry (MWC) is a method invented by George Marsaglia [1] for generating sequences of random integers based on an initial set from two to many thousands of randomly chosen seed values.
The first value the algorithm then generates is based on , not on . The constant f forms another parameter to the generator, though not part of the algorithm proper. The value for f for MT19937 is 1812433253. The value for f for MT19937-64 is 6364136223846793005. [5]

Dice are an example of a mechanical hardware random number generator. When a cubical die is rolled, a random number from 1 to 6 is obtained. Random number generation is a process by which, often by means of a random number generator (RNG), a sequence of numbers or symbols is generated that cannot be reasonably predicted better than by random chance.
the interrupts, mixing CPU cycle counter, kernel timer value, IRQ number, and instruction pointer of the interrupted instruction into a "fast pool" of entropy; the random-time I/O (events from keyboard, mouse, and disk), mixing the kernel timer value, cycle counter, device-specific information into the "input pool".
Random numbers are frequently used in algorithms such as Knuth's 1964-developed algorithm [1] for shuffling lists. (popularly known as the Knuth shuffle or the Fisher–Yates shuffle, based on work they did in 1938). In 1999, a new feature was added to the Pentium III: a hardware-based random number generator.
Wichmann–Hill is a pseudorandom number generator proposed in 1982 by Brian Wichmann and David Hill. [1] It consists of three linear congruential generators with different prime moduli, each of which is used to produce a uniformly distributed number between 0 and 1.
Blum Blum Shub takes the form + =, where M = pq is the product of two large primes p and q.At each step of the algorithm, some output is derived from x n+1; the output is commonly either the bit parity of x n+1 or one or more of the least significant bits of x n+1.
