dwave.embedding.drawing.draw_chimera_bqm#

draw_chimera_bqm(bqm, width=None, height=None)[source]#

Represent a binary quadratic model as a Chimera graph.

Parameters:

  • bqm (BinaryQuadraticModel) – Binary quadratic model equivalent to a Chimera graph or subgraph produced by chimera_graph(), with nodes and edges labeled as integers.

  • width (int, optional) – Number of cells for the graph width. If width and height are not specified, assumes square cell dimensions.

  • height (int, optional) – Number of cells for the graph height. If width and height are not specified, assumes square cell dimensions.

Examples

>>> from dimod import BinaryQuadraticModel
>>> from dwave.embedding.drawing import draw_chimera_bqm
...
>>> Q = {(0, 0): 2, (1, 1): 1, (2, 2): 0, (3, 3): -1, (4, 4): -2,
...      (5, 5): -2, (6, 6): -2, (7, 7): -2, (0, 4): 2, (0, 4): -1,
...      (1, 7): 1, (1, 5): 0, (2, 5): -2, (2, 6): -2, (3, 4): -2,
...      (3, 7): -2}
>>> draw_chimera_bqm(BinaryQuadraticModel.from_qubo(Q), width=1, height=1)
