构造伪随机数引擎。

1%29构造引擎并初始化状态%28n值X

I型result_type%29如下：值mod 2w

用于初始化X。

对于I=1-n，...，-1，每个X，其余的都是迭代初始化的。

我被初始化为。[F.%28X

I-1xor%28X

i-1 rShift%28w-2%29%29%29+i mod n]mod 2w

2%29构造引擎并通过调用s.generate(a, a+n*k)其中a是长度为n的数组。%2AK和k为ceil%28w/32%29，然后迭代地对i=-n，...，-1，设置引擎状态X的每个元素。

I至%28Σk-1

J=0A

K%28i+n%29+j}·232 j

%29 mod 2w

，最后，如果X的最重要的w-r位

0等于零，如果所有其他X

我是零，代替X

0与2w-1

注意：初始化要求基于2002版本的MersenneTwister，mt 19937ar.。丙...

重载%282%29只参与以下情况下的过载解决方案：Sseq有资格SeedSequence.特别是，在下列情况下，它被排除在候选函数集合之外：Sseq可转换为result_type...
