Subject [jira] [Commented] (MATH-1137) BOBYQA incorrect indexing
Date Tue, 15 Jul 2014 15:30:06 GMT


Nigel Goodwin commented on MATH-1137:

As far as I can see, the tests only test the final value. They don't test how many functions
evaluations there have been, or what paths have been followed.

It is very easy to have bugs which do not alter the final solution, but which change the behaviour
and efficiency.

If nobody else has, I will have to allocate some time and do side to side comparisons of Java
and Fortran versions.

The first step may be to see if the Fortran version goes through the steps which the Java
does not....
