dwave.system.composites.VirtualGraphComposite.nodelist

VirtualGraphComposite.nodelist = None

list – Nodes available to the composed sampler.

Examples

This example uses VirtualGraphComposite to instantiate a composed sampler that uses a D-Wave solver selected by the user’s default D-Wave Cloud Client configuration file. Because qubits 0, 1, 4, 5 are active on the selected D-Wave solver, the three nodes, x, y, and z, specified by the embedding, are all available to problems using this composed sampler.

>>> from dwave.system.samplers import DWaveSampler
>>> from dwave.system.composites import VirtualGraphComposite
>>> embedding = {'x': {1}, 'y': {5}, 'z': {0, 4}}
>>> sampler = VirtualGraphComposite(DWaveSampler(), embedding)  
>>> sampler.nodelist  
['x', 'y', 'z']
