TaoTermMask

Determine which evaluation operations are masked; that is, skipped (not used) by Tao when computing the objective function or its derivatives for a particular TaoTerm.

Synopsis

typedef enum {
  TAOTERM_MASK_NONE      = 0, /* 0x0 */
  TAOTERM_MASK_OBJECTIVE = 1, /* 0x1 */
  TAOTERM_MASK_GRADIENT  = 2, /* 0x2 */
  TAOTERM_MASK_HESSIAN   = 4  /* 0x4 */
} TaoTermMask;

Values

• TAOTERM_MASK_NONE - do not mask any evaluation routines

• TAOTERM_MASK_OBJECTIVE - override the term’s objective function and return 0 instead

• TAOTERM_MASK_GRADIENT - override the term’s gradient and return a zero vector instead

• TAOTERM_MASK_HESSIAN - override the term’s Hessian and return a zero matrix instead
