Gilles updated MATH-177:
------------------------
Attachment: UnivariateRealSolverImpl.java
UnivariateRealSolver.java
BrentMinimizer.java
Here are the files discussed on the ML under subject: "[math] Brent
Minimization".
[Although Luc said I should attach them to this issue, they are probably meant
to be included in (or below) the "analysis" package.]
> Provide a general minimizing package with a classical Gauss-Newton algorithm

> Currently the math API provides least squares only method for minimizing
> (solving). The limitation to least-squares problems comes from the
> Levenberg-Marquardt algorithm. A more general minimizer (not for quadratic
> forms) could be implemented by refactoring this with a classical GN, steepest
> descent and also conjugate gradient. We could use them as a basis for some
> least-squares solvers (and also keep the very efficient and specialized
> Levenberg-Marquardt too).
> Based on email exchange with Luc Maisonobe entitled [math] Minimizer on
> 1/15/08.
