#include <../src/tao/bound/impls/bqnk/bqnk.h> /*MC 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_`.
