1 This is the BOBYQA software by M. J. D. Powell, which performs
2 derivative-free unconstrained optimization using an iteratively
3 constructred quadratic approximation for the objective function. See:

13 The C translation by S. G. Johnson (2009) includes a few minor
14 modifications, mainly to use the NLopt stopping criteria (and to
15 take the objective function as an argument rather than a global).
