dwave.system.composites.FixedEmbeddingComposite.sample¶
- FixedEmbeddingComposite.sample(bqm, **parameters)¶
Sample the binary quadratic model.
On the first call of a sampling method, finds a minor-embedding for the given binary quadratic model (BQM). All subsequent calls to its sampling methods reuse this embedding.
- Parameters
bqm (
dimod.BinaryQuadraticModel) – Binary quadratic model to be sampled from.chain_strength (float/mapping/callable, optional) – Sets the coupling strength between qubits representing variables that form a chain. Mappings should specify the required chain strength for each variable. Callables should accept the BQM and embedding and return a float or mapping. By default, chain_strength is calculated with
uniform_torque_compensation().chain_break_method (function, optional) – Method used to resolve chain breaks during sample unembedding. See
unembed_sampleset().chain_break_fraction (bool, optional, default=True) – Add a ‘chain_break_fraction’ field to the unembedded response with the fraction of chains broken before unembedding.
embedding_parameters (dict, optional) – If provided, parameters are passed to the embedding method as keyword arguments. Overrides any embedding_parameters passed to the constructor. Only used on the first call.
**parameters – Parameters for the sampling method, specified by the child sampler.
- Returns
