  TAOBQNKLS - Bounded Quasi-Newton-Krylov Line Search method 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
