WebMar 17, 2010 · Given a perfect pseudo-random number generator (the Mersenne Twister is very close), the Fisher-Yates algorithm is perfectly unbiased in that every permutation has an equal probability of occurring. This is easy to prove using induction. The Fisher-Yates algorithm can be written recursively as follows (in Python syntax pseudocode):
