HANSO: Hybrid Algorithm for Non-Smooth Optimization
A MATLAB package based on the BFGS and gradient sampling methods.
For general unconstrained minimization: convex or nonconvex, smooth or nonsmooth,
including BFGS, limited memory BFGS and gradient sampling methods.
HANSO is based upon work supported by the National Science Foundation (NSF).
Any opinions, findings and conclusions or recommendations expressed in this material are those
