# Optimization converters (qiskit.optimization.converters)¶

This is a set of converters having convert functionality to go between different representations of a given QuadraticProgram and to interpret a given result for the problem, based on the original problem before conversion, to return an appropriate OptimizationResult.

# Base class for converters¶

 QuadraticProgramConverter An abstract class for converters of quadratic programs in Qiskit’s optimization module.

# Converters¶

 InequalityToEquality Convert inequality constraints into equality constraints by introducing slack variables. IntegerToBinary Convert a QuadraticProgram into new one by encoding integer with binary variables. LinearEqualityToPenalty Convert a problem with only equality constraints to unconstrained with penalty terms. QuadraticProgramToQubo Convert a given optimization problem to a new problem that is a QUBO.
