Node Recorder
General Description
Section titled “General Description”Attributes
Section titled “Attributes”| Name | Description | Required |
|---|---|---|
| model | pywr.core.Model | Yes |
| agg_func | Scenario aggregation function to use when aggregated_value is called | Yes |
| name | Name of the recorder | |
| comment | Comment or description of the recorder | |
| ignore_nan | Flag to ignore NaN values when calling aggregated_value | |
| is_objective | Flag to denote the direction, if any, of optimisation undertaken with this recorder | |
| epsilon | Epsilon distance used by some optimisation algorithms | |
| constraint_lower_bounds, constraint_upper_bounds | The value(s) to use for lower and upper bound definitions. These values determine whether the recorder instance is marked as a constraint. Either bound can be None (the default) to disable the respective bound. If both bounds are None then the is_constraint property will return False. The lower bound must be strictly less than the upper bound. An equality constraint can be created by setting both bounds to the same value. The constraint bounds are not used during model simulation. Instead they are intended for use by optimisation wrappers (or other external tools) to define constrained optimisation problems. |
