[jira] [Updated] (MATH-902) org.apache.commons.math3.exception.TooManyEvaluationsException should return best found result

     [ https://issues.apache.org/jira/browse/MATH-902?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Gilles updated MATH-902:
------------------------

             Priority: Minor  (was: Major)
    Affects Version/s:     (was: 3.1)
           Issue Type: Wish  (was: Bug)

Changing the issue type: this is definitely not a bug, perhaps a shortcoming of the chosen API.

It would help focusing the discussion (that happens on the "dev" ML) if you could provide an actual use-case.

> The org.apache.commons.math3.exception.TooManyEvaluationsException should contain within it the best found solution so far. There are numerous examples when the optimization might not have converged to the stopping condition but the minimum point is better than the starting point that was provided. The user should have the ability to at least decide if it is good enough, or use it as a starting point into a different optimization run.
