If c ≠ 0, the method is called a mixed congruential generator. citation Period length The period of a general mixed congruential generator is at most m, and for some choices of factor a much less than that. Source: Internet
Linear congruential generators have the problem that all of the bits in each number are usually not equally random. Source: Internet
