This would of course depend on the kind of optimization you are trying to
do.  If you have a global optimization problem with lots of local optima,
perhaps ECJ's ES or PSO packages might do the trick.  Otherwise, if your
problem is really largely a basic gradient descent problem, ECJ might be
too complex.  At any rate, Liviu and I know ECJ well.
