netket.hilbert.constraint.ExtraConstraint

class netket.hilbert.constraint.ExtraConstraint

Bases: ExtraConstraint

Wraps a Constraint and its HilbertIndex into a second constraint (with a default lookup-based hilbert index).

The first argument is the base constraint while the second is the wrapping one.

Methods

__call__(x)

This function should take as input a matrix encoding a batch of configurations, and return a vector of booleans specifying whether they are valid configurations of the Hilbert space or not.

Parameters:

x (Array) – 2D matrix.

Return type:

Array

replace(**kwargs)

Replace the values of the fields of the object with the values of the keyword arguments. If the object is a dataclass, dataclasses.replace will be used. Otherwise, a new object will be created with the same type as the original object.

Return type:

TypeVar(P, bound= Pytree)

Parameters:

• self (P)

• kwargs (Any)
