Why are std::shuffle methods being deprecated in C++14?

Question

According to the cppreference.com reference site on std::shufle, the following method is being deprecated in c++14:

template< class RandomIt >
void ran         


        

Answer 1

random_shuffle is being deprecated because its RNG is unspecified -- not just that you don't have to specify it, but that the standard itself doesn't specify it. On VC++, for instance, it uses rand(), which is implemented really poorly!
