4   TAOBQNKLS - Bounded Quasi-Newton-Krylov Line Search method for nonlinear minimization with
5               bound constraints. This method approximates the Hessian-vector product using a
6               limited-memory quasi-Newton formula, and iteratively inverts the Hessian with a
7               Krylov solver. The quasi-Newton matrix and its settings can be accessed via the
8               prefix `-tao_bqnk_`. For options database, see `TAOBNK`
