TAOBQNKTL#

Bounded Quasi-Newton-Krylov Trust-region with Line-search fallback, for nonlinear minimization with bound constraints. This method approximates the Hessian-vector product using a limited-memory quasi-Newton formula, and iteratively inverts the Hessian with a Krylov solver. The quasi-Newton matrix and its settings can be accessed via the prefix -tao_bqnk_. For options database, see TAOBNK
