A solver for derivative-free optimization

DFO-TR is a solver for continuous optimization problems which does not use any derivatives of the objective function. It is based on a trust-region interpolation-based method. The current version is for unconstrained problems.

• DFO-TR (Version 0.1, November 2021) is written in Matlab.
