Return the state of the node.

Parameters:

• index – Index of the state.

• copy – Currently only True is supported.

Returns:

State as a numpy.ndarray.

Examples

This example prints a node two states: initialized and uninitialized.

>>> from dwave.optimization import Model
>>> model = Model()
>>> x = model.binary((2, 3))
>>> z = x.sum()
>>> with model.lock():
...     model.states.resize(2)
...     x.set_state(0, [[0, 0, 1], [1, 0, 1]])
...     print(z.state(0))
...     print(z.state(1))
