- BinaryQuadraticModel.to_qubo() Tuple[Mapping[Tuple[Hashable, Hashable], Union[float, numpy.floating, numpy.integer]], Union[float, numpy.floating, numpy.integer]] [source]¶
Convert a binary quadratic model to QUBO format.
If the binary quadratic model’s vartype is not
Vartype.BINARY
, values are converted.- Returns
2-tuple of form
({(u, v): bias, ...}, offset)
, whereu
,v
, are binary-valued variables andbias
is their associated coefficient, andoffset
is a number that represents the constant offset of the binary quadratic model.- Return type
