discrete doesn't sort the weights either if you notice.
The initialization for discrete is more complex and
is almost certainly slower, although it is still O(n) where
n is the number of elements in the sequence of weights.
I didn't try to optimize the initialization much, so it
is quite likely to be several times slower than it could be.
