dimod.higherorder.polynomial.BinaryPolynomial.to_hising#

BinaryPolynomial.to_hising()[source]#

Construct a higher-order Ising problem from a binary polynomial.

Returns:: A 3-tuple of the form (h, J, offset) where h includes the linear biases, J has the higher-order biases and offset is the linear offset.
Return type:: tuple

Examples

>>> poly = dimod.BinaryPolynomial({'a': -1, ('a', 'b'): 1, ('a', 'b', 'c'): -1}, dimod.SPIN)
>>> h, J, off = poly.to_hising()
>>> h
{'a': -1}
