Luc Maisonobe commented on MATH-466:
------------------------------------

Yes, the javadoc should be changed and the number of starts should be checked with an error triggered if it is not at least 1.

> 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?
