Inversive congruential generator

Inversive congruential generator

Inversive congruential generators are a type of nonlinear congruential pseudorandom number generator, which use the modular multiplicative inverse (if it exists) to generate the next number in a sequence. The standard formula for an inversive congruential generator is

:x_{i+1} equiv (ax_{i}^{-1} + c) pmod m

where 0 < x_{i} < m.
