InequalityToEquality¶

class InequalityToEquality(mode='auto')[source]¶

Bases: qiskit.optimization.converters.quadratic_program_converter.QuadraticProgramConverter

Convert inequality constraints into equality constraints by introducing slack variables.

Examples

>>> from qiskit.optimization.problems import QuadraticProgram
>>> from qiskit.optimization.converters import InequalityToEquality
>>> problem = QuadraticProgram()
>>> # define a problem
>>> conv = InequalityToEquality()
>>> problem2 = conv.convert(problem)

Parameters

mode (str) –

To chose the type of slack variables. There are 3 options for mode.

’integer’: All slack variables will be integer variables.
’continuous’: All slack variables will be continuous variables
’auto’: Try to use integer variables but if it’s not possible,
use continuous variables

Methods

`convert`	Convert a problem with inequality constraints into one with only equality constraints.
`interpret`	Convert a result of a converted problem into that of the original problem.

Attributes

mode¶

Returns the mode of the converter

Return type: str
Returns: The mode of the converter used for additional slack variables
