Provenance

class Provenance

One step in a regular constraint’s transformation history.

When a special constraint (indicator / one-hot / SOS1) is converted into a regular Constraint — for example via Instance.convert_one_hot_to_constraint or Instance.reduce_capabilities — the generated constraint records a Provenance entry naming the original special constraint. This lets callers trace a regular constraint back to the special constraint it was derived from.

__eq__(other: object) → bool

__hash__() → int

__repr__() → str
