Bound-Constrained Flash (BCFLASH)¶
BCFLASH is a Steighaug Conjugate-Gradient type solver for optimization problems of the form:
\[\min_{x \in \mathbb{R}^n}\enspace f(x) \enspace\mbox{subject to}\enspace \ell \le x \le u\]
where \(f\) has two continuous derivatives; it is essentially a MATLAB implementation of TRON.
