ZibTranslator ¶

Utility class for converting between a Zib solution and our solution format.

ZibTranslator provides methods to:

- Convert a Zib-style solution into our solution `Solution`.

The conversions are especially required when interacting with external zib solvers/samplers or libraries that operate on zib-based problem-solving/sampling.

Examples:

>>> import luna_quantum as lq
>>> from pyscipopt import Model
>>> model = Model()
>>> model.readProblem("./path/to/my/model.lp")
>>> model.optimize()
>>> aqs = lq.translator.ZibTranslator.to_aq(model)

to_aq `staticmethod` ¶

to_aq(model: Model) -> Solution

to_aq(model: Model, timing: Timing) -> Solution

to_aq(model: Model, *, env: Environment) -> Solution

to_aq(model: Model, timing: Timing, *, env: Environment) -> Solution

to_aq(
    model: Model, timing: Timing | None = ..., *, env: Environment | None = ...
) -> Solution

Extract a solution from a ZIB model.

Parameters:

Name	Type	Description	Default
`model`	`Model`	The Model that ran the optimization.	required
`timing`	`Timing`	The timing object produced while generating the result.	`...`
`env`	`Environment`	The environment of the model for which the result is produced.	`...`

Raises:

Type	Description
`NoActiveEnvironmentFoundError`	If no environment is passed to the method or available from the context.
`SolutionTranslationError`	Generally if the solution translation fails. Might be specified by one of the two following errors.
`SampleIncorrectLengthError`	If a solution's sample has a different number of variables than the model environment passed to the translator.
`ModelVtypeError`	If the result's variable types are incompatible with the model environment's variable types.
