ExactCQMSolver.sample_cqm(cqm: dimod.constrained.constrained.ConstrainedQuadraticModel, *, rtol: float = 1e-06, atol: float = 1e-08, **kwargs) → dimod.sampleset.SampleSet

Sample from a constrained quadratic model.

Parameters

• cqm – Constrained quadratic model to be sampled from.

• rtol – Relative tolerance for constraint violation. The fraction of a constraint’s right hand side which any violation must be smaller than for the constraint to be satisfied.

• atol – Absolute tolerance for constraint violations. A constant any violation must be smaller than for the constraint to be satisfied.

Returns

A sampleset of all possible samples, with the fields is_feasible and is_satisfied containing total and individual constraint violation information, respectively.
