Examples

Encode and decode using JSON

>>> import json
...
>>> bqm = dimod.BinaryQuadraticModel({'a': -1.0, 'b': 1.0},
...                                  {('a', 'b'): -1.0},
...                                  0.0,
...                                  dimod.SPIN)
>>> s = json.dumps(bqm.to_serializable())
>>> new_bqm = dimod.BinaryQuadraticModel.from_serializable(json.loads(s))
