This functionality defines the dlib interface towards the BOBYQA software developed by M.J.D Powell. BOBYQA is a technique for optimizing a operate from the absence of derivative information. Powell explained it as a method that seeks the the very least value of a operate of many variables, by applying a belief area technique that kinds quadratic styles by interpolation. There is generally some flexibility during the interpolation problems, that's taken up by minimizing the Frobenius norm of your transform to the second by-product on the model, beginning with the zero matrix.
