# dwave.system.composites.TilingComposite.sample¶

TilingComposite.sample(bqm, **kwargs)[source]

Sample from the specified binary quadratic model.

Parameters: bqm (dimod.BinaryQuadraticModel) – Binary quadratic model to be sampled from. **kwargs – Optional keyword arguments for the sampling method, specified per solver. dimod.SampleSet

Examples

This example submits a simple Ising problem of just two variables on a D-Wave system. Because the problem fits in a single Chimera unit cell, it is tiled across the solver’s entire Chimera graph, resulting in multiple samples (the exact number depends on the working Chimera graph of the D-Wave system).

>>> from dwave.system import DWaveSampler, EmbeddingComposite
>>> from dwave.system import TilingComposite
...
>>> qpu_2000q = DWaveSampler(solver={'topology__type': 'chimera'})
>>> sampler = EmbeddingComposite(TilingComposite(qpu_2000q, 1, 1, 4))
>>> response = sampler.sample_ising({},{('a', 'b'): 1})
>>> len(response)    # doctest: +SKIP
