dimod.bqm.adjarraybqm.AdjArrayBQM.from_numpy_vectors

AdjArrayBQM.from_numpy_vectors(type cls, linear, quadratic, offset, vartype, variable_order=None)

Create a binary quadratic model from vectors.

Parameters

• linear (array_like) – A 1D array-like iterable of linear biases.

• quadratic (tuple[array_like, array_like, array_like]) – A 3-tuple of 1D array_like vectors of the form (row, col, bias).

• offset (numeric, optional) – Constant offset for the binary quadratic model.

• vartype (Vartype/str/set) –

  Variable type for the binary quadratic model. Accepted input values:

  • Vartype.SPIN, 'SPIN', {-1, 1}

  • Vartype.BINARY, 'BINARY', {0, 1}

• variable_order (iterable, optional) – If provided, labels the variables; otherwise, indices are used.

Returns

A binary quadratic model
