Hello all,
We've noticed that normal_distribution using polar method, rather then Box-Muller.
Is there a particular reason for not using Box-Muller?
Looks to me like a quite an easy way to improve performance. The method with source code is described in Numerical Recipes.
Changing current code to Box-Muller is just a few line code change.
It improved performance of one of my apps by 20%, so the normal_distribution performance was even bigger.
