DWaveSampler

class DWaveSampler(solver_name=None, url=None, token=None, proxies=None, permissive_ssl=False)

dimod wrapper for a D-Wave Micro Client.

Parameters:

• solver_name (str, optional) – Id of the requested solver. None will return the default solver (see configuration).
• url (str, optional) – URL of the SAPI server. None will return the default url (see configuration).
• token (str, optional) – Authentication token from the SAPI server. None will return the default token (see configuration).
• proxies (dict, optional) – Mapping from the connection scheme (http[s]) to the proxy server address.
• permissive_ssl (boolean, optional, default=False) – Disables SSL verification.

structure

tuple –

A named 3-tuple with the following properties/values:

nodelist (list): The nodes available to the sampler.

edgelist (list[(node, node)]): The edges available to the sampler.

adjacency (dict): Encodes the edges of the sampler in nested dicts. The keys of adjacency are the nodes of the sampler and the values are neighbor-dicts.

accepted_kwargs

dict[str, dimod.SamplerKeywordArg] – The keyword arguments accepted by the sample_ising and sample_qubo methods for this sampler.

my_kwargs()

The keyword arguments accepted by DWaveSampler

Returns:SamplerKeywordArg]: The keyword arguments accepted by the sample_ising and sample_qubo methods for this sampler or the top-level composite layer. For all accepted keyword arguments see accepted_kwargs. Return type:dict[str

sample_ising(linear, quadratic, **kwargs)

Sample from the provided Ising model.

Parameters:

• linear (list/dict) – Linear terms of the model.
• quadratic (dict of (int, int) – float): Quadratic terms of the model.
• **kwargs – Parameters for the sampling method, specified per solver.

Returns:

FutureResponse

sample_qubo(Q, **kwargs)

Sample from the provided QUBO.

Parameters:

• Q (dict) – The coefficients of the QUBO.
• **kwargs – Parameters for the sampling method, specified per solver.

Returns:
