mt19937

Mersenne Twister engine is a random number engine based on Mersenne Twister algorithm. More specifically, it is a Mersenne Twister pseudorandom number generator with period LaTex Math image. [Matsumoto98].
Subsequence selection methods support
skipAhead (nskip)
Supported
leapfrog (threadIdx, nThreads)
Not supported

Batch Processing

Mersenne Twister engine needs the initial condition (
seed
) for state initialization. The seed can be either an integer scalar or a vector of LaTex Math image. integer elements, the inputs to the respective engine constructors.
Algorithm Parameters
Mersenne Twister engine has the following parameters:
