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....
