Numerical Recipes from the "quick and dirty generators" list, Chapter 7.1, Eq. Output bits of seed in rand() or Random(L) This table is to show popularity, not examples to emulate many of these parameters are poor. The following table lists the parameters of LCGs in common use, including built-in rand() functions in runtime libraries of various compilers. If you were taking As or A level maths Id say use the formula: ar (n-1) where. ( Original post by BabyMaths) Since you have division by 3 at each step you could put the power of three on the bottom of the fraction: 162/31, 162/32, 162/33.
Linear sequences mod#
X n + 1 = ( a X n + c ) mod m Parameters in common use Multiply each term by a certain factor, look at BabyMaths post 10.
Linear sequences generator#
The generator is defined by the recurrence relation:
The theory behind them is relatively easy to understand, and they are easily implemented and fast, especially on computer hardware which can provide modular arithmetic by storage-bit truncation. The method represents one of the oldest and best-known pseudorandom number generator algorithms. Ī linear congruential generator ( LCG) is an algorithm that yields a sequence of pseudo-randomized numbers calculated with a discontinuous piecewise linear equation. Using a = 4 and c = 1 (bottom row) gives a cycle length of 9 with any seed in. The second row is the same generator with a seed of 3, which produces a cycle of length 2. The top row shows a generator with m = 9, a = 2, c = 0, and a seed of 1, which produces a cycle of length 6. Each row shows the state evolving until it repeats.
