  4:   TAOBQNKTR - Bounded Quasi-Newton-Krylov Trust Region 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_`
