Detailed Description

Random Number generator 'Mersenne Twister' This random number generator is described in the article by M. Matsumoto & T. Nishimura, in: ACM Transactions on Modeling and Computer Simulation, vol. 8, no. 1, 1998, pp. 3-30.

Note
Experts consider this an excellent random number generator. RESOLUTION = 32 bits
