Subject [jira] Commented: (MATH-466) BaseMultiStartMultivariateRealOptimizer.optimize() can generate NPE if starts < 1
Date Thu, 06 Jan 2011 19:50:46 GMT

    [ https://issues.apache.org/jira/browse/MATH-466?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12978473#action_12978473
] 

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.

> BaseMultiStartMultivariateRealOptimizer.optimize() can generate NPE if starts < 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?
