OneHotConstraint

class OneHotConstraint

A one-hot constraint: exactly one variable must be 1, the rest must be 0.

This is a structural constraint — no explicit function is stored. The implicit constraint is sum(x_i) = 1 where all x_i are binary.

__copy__() → OneHotConstraint

__deepcopy__(_memo: Any) → OneHotConstraint

__new__(variables: Sequence[int], name: Optional[str] = None, subscripts: Sequence[int] = [], description: Optional[str] = None, parameters: Mapping[str, str] = {}) → OneHotConstraint

Create a new one-hot constraint.

Args:

• variables: List of binary decision variable IDs (exactly one must be 1)

• name / subscripts / description / parameters: Optional metadata. Drained into the host's SoA store on insertion.

__repr__() → str

set_description(description: str) → OneHotConstraint

Set the description. Returns self for method chaining (snapshot mutation).

set_name(name: str) → OneHotConstraint

Set the name. Returns self for method chaining (snapshot mutation).

set_parameters(parameters: Mapping[str, str]) → OneHotConstraint

Replace all parameters. Returns self for method chaining (snapshot mutation).

set_subscripts(subscripts: Sequence[int]) → OneHotConstraint

Set the subscripts. Returns self for method chaining (snapshot mutation).
