pywr.parameters.OffsetParameter

class pywr.parameters.OffsetParameter(model, parameter, offset=0.0, lower_bounds=0.0, upper_bounds=np.inf, *args, **kwargs)

Parameter that offsets another Parameter by a constant value.

This class is a more efficient version of AggregatedParameter where a single Parameter is offset by a constant value.

Parameters:

parameterParameter

The parameter to compare with the float.

offsetfloat (default=0.0)

The offset to apply to the value returned by parameter.

lower_boundsfloat (default=0.0)

The lower bounds of the offset when used during optimisation.

upper_boundsfloat (default=np.inf)

The upper bounds of the offset when used during optimisation.
