dwave.optimization.model.Model.objective

Model.objective

Objective to be minimized.

Examples

This example prints the value of the objective of a model representing the simple polynomial, \(y = i^2 - 4i\), for a state with value \(i=2.0\).

>>> from dwave.optimization import Model
...
>>> model = Model()
>>> i = model.integer(lower_bound=-5, upper_bound=5)
>>> c = model.constant(4)
>>> y = i**2 - c*i
>>> model.minimize(y)
>>> with model.lock():
...     model.states.resize(1)
...     i.set_state(0, 2.0)
...     print(f"Objective = {model.objective.state(0)}")
Objective = -4.0
