[jira] Commented: (MATH-466) BaseMultiStartMultivariateRealOptimizer.optimize() can generate NPE if starts < 1

>                 Key: MATH-466
>                 URL: https://issues.apache.org/jira/browse/MATH-466
>             Project: Commons Math
>          Issue Type: Bug
>    Affects Versions: 3.0
>            Reporter: Sebb

> The Javadoc for BaseMultiStartMultivariateRealOptimizer says that starts can be <= 1; however if it is set to 0, then the optimize() method will try to throw a null exception.
> Perhaps starts should be constrained to be at least 1?
