TAOBNTL#

Bounded Newton Trust Region method with line-search fall-back for nonlinear minimization with bound constraints.

Options Database Keys#

  • -tao_bnk_max_cg_its - maximum number of bounded conjugate-gradient iterations taken in each Newton loop . -tao_bnk_init_type - trust radius initialization method (“constant”, “direction”, “interpolation”) . -tao_bnk_update_type - trust radius update method (“step”, “direction”, “interpolation”)

  • -tao_bnk_as_type - active-set estimation method (“none”, “bertsekas”)

Developer Note#

One should control the maximum number of cg iterations through the standard pc_max_it option not with a special ad hoc option

Level#

beginner
