• What does linear congruential generator do?

  A linear congruential generator (LCG) is an algorithm that yields a sequence of pseudo-randomized numbers calculated with a discontinuous piecewise linear equation. The method represents one of the oldest and best-known pseudorandom number generator algorithms.

• What is the formula for linear congruential generator?

  An LCG is defined by the equation L_n ? (a ? L_n-1 + c) mod m, where the values of m (the modulus, a positive integer), a (the multiplier, a positive integer less than m) and c (the increment, either 0 or a positive integer less than m) are chosen by the designer of the LCG.

• How do you calculate LCG period?

  Full-Period Theorem (Hull and Dobell, 1966) In general, cycle length determined by parameters m, a, and c: The LCG Zi = (aZi-1 + c) (mod m) has full period (m) if and only all three of the following hold: 1. c and m are relatively prime (i.e., the only positive integer that divides both c and m is 1).
• The simple form of the LCG algorithm is as follows: X n+1 = (a X n +b) mod m , n? 0 ; A constant in the above algorithm is called a multiplier, the constant b is called an increment, and the constant m is called modulus.
