What’s the easiest way to create a variable pointing to the
function beta, which calls the two-argument function alpha,
but with the arguments swapped?
bind(beta, alpha, 2, 1);
auto beta = bind(alpha, 2, 1);
auto beta = bind(alpha, _2, _1);
int beta(int a, int b) { return alpha(b,a); }
minstd_rand?x = x * 48271 % 2147483647 // always positive, never zero
The mt19937 RNG is deterministic—given the same seed, it will
produce the same sequence of numbers each time.
mt19937 is not a generator.
