dimod.generators.or_gate#

or_gate(in0: Hashable, in1: Hashable, out: Hashable, *, strength: float = 1.0) → BinaryQuadraticModel[source]#

Generate a binary quadratic model with ground states corresponding to an OR gate.

Parameters:

  • in0 – Variable label for one of the inputs.

  • in1 – Variable label for one of the inputs.

  • out – Variable label for the output.

  • strength – Energy of the lowest-energy infeasible state.

Returns:

A binary quadratic model with ground states corresponding to an OR gate. The model has three variables and three interactions.

Examples

>>> bqm = dimod.generators.or_gate('x1', 'x2', 'z')
>>> print(dimod.ExactSolver().sample(bqm).lowest())
  x1 x2  z energy num_oc.
