dimod.ConstrainedQuadraticModel.set_lower_bound

ConstrainedQuadraticModel.set_lower_bound()[source]

Set the lower bound for a variable.

Parameters

  • v – Variable label of a variable in the constrained quadratic model.

  • lb – Lower bound to set for variable v.

Raises

ValueError – If v is a SPIN or BINARY variable.

Examples

>>> cqm = dimod.ConstrainedQuadraticModel()
>>> cqm.add_variable('INTEGER', 'j', upper_bound=5)
'j'
>>> cqm.set_lower_bound('j', 2)
