+objective minimization, without requiring derivatives of the objective.  At
+its core, it is a Python implementation of the BOBYQA algorithm by Powell,but
+Py-BOBYQA has extra features improving its performance on some problems.
+Py-BOBYQA is particularly useful when evaluations of the objective function
+are expensive and/or noisy.")
