Up to now, computers are only able to do deterministic tasks and they cannot generate true random numbers. To sample random numbers, they run deterministic sequences called pseudorandom number generators that produce a sequence of real numbers in [0, 1] that behaves like a sequence of independent random variables that are distributed uniformly on [0, 1]. Different families of pseudorandom number generators exist. It is important to use generators that have a large period, such as the Mersenne twister. In fact, running a Monte-Carlo algorithm to compute pathwise expectations may use intensively the generator. The convergence of the Monte-Carlo algorithm is degraded when the amount of pseudorandom numbers used is close or larger than the period.
