In my geophysical work, I rely heavily upon a generalized inversion algorithm called Gauss-Newton optimization. The Gauss-Newton method minimizes objective functions that can be iteratively approximated by quadratics. This approach is particularly appropriate for least-squares inversions of ... [More] moderately non-linear transforms. The package also contains code for conjugate-gradient and line-search optimizations. Over two decades I have implemented this package four times, in four different programming languages. Every feature of this package has been motivated by practical application. This particular Java version is only a few years old, but I have already used it for a dozen or more distinct inversion problems. I find no preexisting package so suitable for typical geo [Less]
