# TaoALMMType

Determine the augmented Lagrangian formulation used in the `TAOALMM` subproblem.

## Synopsis

    typedef enum {
      TAO_ALMM_CLASSIC,
      TAO_ALMM_PHR
    } TaoALMMType;

## Values

- `TAO_ALMM_CLASSIC` - classic augmented Lagrangian definition including slack variables for inequality constraints

- `TAO_ALMM_PHR` - Powell-Hestenes-Rockafellar formulation without slack variables, uses pointwise `min()` for inequalities
