As it's been advertized in all release notes since version 3.0, the
code in "BOBYQAOptimizer" is alpha. The code seems to work as the
FORTRAN original but is otherwise extremely difficult to modify
without ill consequences. In particular, it's not reached as state
where a custom convergence checker could have been easily added.
