dimod.reference.samplers.ExactSolver.sample

ExactSolver.sample(bqm, **kwargs)

Sample from a binary quadratic model.

Parameters:bqm (BinaryQuadraticModel) – Binary quadratic model to be sampled from. Returns:A dimod Response object. Return type:Response

Examples

This example provides samples for a two-variable Ising model.

>>> import dimod
>>> sampler = dimod.ExactSolver()
>>> bqm = dimod.BinaryQuadraticModel({0: 0.0, 1: 1.0}, {(0, 1): 0.5}, -0.5, dimod.SPIN)
>>> response = sampler.sample(bqm)
>>> response.data_vectors['energy']
array([-1., -2.,  1.,  0.])
