IntegerToBinary¶

class IntegerToBinary[source]¶

Bases: qiskit.optimization.converters.quadratic_program_converter.QuadraticProgramConverter

Convert a QuadraticProgram into new one by encoding integer with binary variables.

This bounded-coefficient encoding used in this converted is proposed in [1], Eq. (5).

Examples

>>> from qiskit.optimization.problems import QuadraticProgram
>>> from qiskit.optimization.converters import IntegerToBinary
>>> problem = QuadraticProgram()
>>> var = problem.integer_var(name='x', lowerbound=0, upperbound=10)
>>> conv = IntegerToBinary()
>>> problem2 = conv.convert(problem)

Methods

`convert`	Convert an integer problem into a new problem with binary variables.
`interpret`	Convert back the converted problem (binary variables) to the original (integer variables).
