        Constraint

Known Subclasses:

Represents a constraint of a function.

Constraints must take a parameter penalty_start, with default value 0.
Columns, variables or corresponding entities with indices smaller than
penalty_start must not be penalised.

Parameters

penalty_start : The number of columns, variables etc., to except from
        penalisation. Equivalently, the first index to be penalised.
        Default is 0, all columns are included.
