`openjij.model.king_graph`#

`KingGraph`([linear, quadratic, offset, king_graph, ...])	Generate KingGraph model.
`make_KingGraph`([linear, quadratic, king_graph])	KingGraph factory
`make_KingGraph_from_JSON`(obj)	KingGraph factory for JSON

openjij.model.king_graph.KingGraph(linear=None, quadratic=None, offset=0.0, king_graph=None, vartype=SPIN, machine_type='')[source]#

Generate KingGraph model.

Parameters:

linear (dict) – linear biases
quadratic (dict) – quadratic biases
offset (float) – offset
king_graph –
represents ising or QUBO interaction. Each spins are decided by 2-d corrdinate x, y.
- Quadratic term: [x1, y1, x2, y2, value]
- Linear term: [x1, y1, x1, y1, value]
vartype – ‘SPIN’ or ‘BINARY’
machine_type (str) – choose ‘ASIC’ or ‘FPGA’

Returns:

generated KingGraphModel

Examples

The following code shows intialization of KingGraph:

>>> h = {}
>>> J = {(0, 1): -1.0, (1, 2): -3.0}
>>> king_graph = oj.KingGraph(machine_type="ASIC", linear=h, quadratic=J)

You can initialize it from king_interaction:

>>> king_interaction = [[0, 0, 1, 0, -1.0], [1, 0, 2, 0, -3.0]]
>>> king_graph = oj.KingGraph(machine_type="ASIC", king_graph=king_interaction)
