# SNESNormSchedule
Frequency with which the norm is computed 
## Synopsis
```
typedef enum {
  SNES_NORM_DEFAULT            = -1,
  SNES_NORM_NONE               = 0,
  SNES_NORM_ALWAYS             = 1,
  SNES_NORM_INITIAL_ONLY       = 2,
  SNES_NORM_FINAL_ONLY         = 3,
  SNES_NORM_INITIAL_FINAL_ONLY = 4
} SNESNormSchedule;
```


Support for these is highly dependent on the solver.


## Notes
This is primarily used to turn off extra norm and function computation
when the solvers are composed.
