Alias std.random.Mt19937
A MersenneTwisterEngine
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 LinearCongruentialEngine
would be the generator of choice.
alias Mt19937
= MersenneTwisterEngine!(uint,32L,624L,397L,31L,2567483615,11L,4294967295,7L,2636928640,15L,4022730752,18L,1812433253);
Example
// seed with a constant
Mt19937 gen;
auto n = gen .front; // same for each run
writeln(n); // 3499211612
// Seed with an unpredictable value
gen .seed(unpredictableSeed);
n = gen .front; // different across runs
