Detailed Description

Random number distributions.

The yat random number related functionality is placed within the random namespace.

Function Documentation

template<typename InputIterator , typename Size1 , typename Size2 , typename OutputIterator >
OutputIterator theplu::yat::random::copy_k_of_n ( InputIterator  it,
Size1  k,
Size2  n,
OutputIterator  out 
)

Copy k random element out of range [it, it+n) into output range [out, out+k).

Each element in the input range is copied with equal probability: k/n.

Type Requirements:

Returns
iterator one-passed the last element copied

template<typename RandomAccessIterator >
void theplu::yat::random::random_shuffle ( RandomAccessIterator  first,
RandomAccessIterator  last 
)

Convenience function to shuffle a range with singleton RNG.

Wrapper around std::random_shuffle using DiscreteUniform as random generator and thereby using the underlying RNG class, which is singleton.

Type Requirements:
