D-Wave SAPI dimod

A dimod wrapper for SAPI.

Installation

For python 2

python setup.py install

Examples

Loading the module

>>> import dwave_sapi_dimod as sapi

Initializing a remote solver

>>> url = "http://myURL"
>>> token = "myToken001"
>>> solver_name = "solver_name"
>>> solver = sapi.SAPISampler(solver_name, url, token)

Initializing a local solver.

>>> solver_name = 'c4-sw_optimize'
>>> solver = sapi.SAPILocalSampler(solver_name)

sample_qubo and sample_ising work only for problems that fit directly onto the solver's structure

>>> h = {0: -.1, 4: .1}
>>> J = {(0, 4): -1}
>>> response = solver.sample_ising(h, J)
>>> list(response.samples())
[{0: -1, 4: -1}, {0: 1, 4: 1}, {0: 1, 4: -1}, {0: -1, 4: 1}]
>>> list(response.energies())
[-1.0, -1.0, 0.8, 1.2]

For solving arbitrary problems, you need to apply the EmbeddingComposite layer.

>>> solver = sapi.EmbeddingComposite(sapi.SAPILocalSampler(solver_name))
>>> h = {0: -.1, 1: .1}
>>> J = {(0, 1): -1}
>>> response = solver.sample_ising(h, J)
>>> list(response.samples())
[{0: -1, 1: -1}, {0: 1, 1: 1}, {0: 1, 1: -1}, {0: -1, 1: 1}]
>>> list(response.energies())
[-1.0, -1.0, 0.8, 1.2]

See dimod documentation for full description of the response object.
