ROSE_DLL_API bool Rose::Combinatorics::flip_coin | ( | ) |
Simulate flipping a coin.
Randomly returns true or false with equal probability.
void Rose::Combinatorics::shuffle | ( | std::vector< T > & | vector, |
size_t | nitems = UNLIMITED , |
||
size_t | limit = UNLIMITED |
||
) |
Shuffle the values of a vector.
This algorithm randomly shuffles the items in the vector by swapping values at indexes zero through limit
with values at randomly selected indexes zero through nitems
. The defaults for nitems
and limit
are the size of the input vector
.

std::vector<std::pair<T, U> > Rose::Combinatorics::zip | ( | const std::vector< T > & | first, |

) |
Convert two vectors to a vector of pairs.
If the two input vectors are not the same length, then the length of the result is the length of the shorter input vector.
