qiskit_addon_opt_mapper.converters.BinaryToSpin¶

class BinaryToSpin[source]¶

Convert all binary variables in the problem to spin variables.

The conversion is done by the relation b_i = (1 - s_i)/2 where b_i is a binary variable and s_i is a spin variable.

Initialize converter.

Initialize converter.

Methods

`__init__`()	Initialize converter.
`convert`(problem)	Convert all binary variables in the problem to spin variables.
`interpret`(x)	Convert a solution of the converted problem back to a solution of the original problem.

convert(problem)[source]¶

Convert all binary variables in the problem to spin variables.

interpret(x)[source]¶

Convert a solution of the converted problem back to a solution of the original problem.

For binaries that became spins, we use b = (1 - s)/2.
