Alias std.random.Mt19937
A
instantiated with the parameters of the
original engine
MT19937, generating uniformly-distributed 32-bit numbers with a
period of 2 to the power of 19937. Recommended for random number
generation unless memory is severely restricted, in which case a MersenneTwisterEngine
would be the generator of choice.

Declaration
alias Mt19937 = MersenneTwisterEngine!(uint,32L,624L,397L,31L,2567483615,11L,7L,2636928640,15L,4022730752,18L)
;
Example
// seed with a constant Mt19937 gen; auto n = gen.front; // same for each run // Seed with an unpredictable value gen.seed(unpredictableSeed); n = gen.front; // different across runs
