Continuation Interfaces

The interfaces module provides interface classes that adapt the generic continuation engine to specific problem domains.

Periodic Orbit Continuation Interface

_PeriodicOrbitContinuationInterface()

Adapter wiring periodic-orbit families to continuation backends.

class hiten.algorithms.continuation.interfaces._PeriodicOrbitContinuationInterface

Bases: _HitenBaseInterface[_OrbitContinuationConfig, _ContinuationProblem, ContinuationResult, tuple[list[ndarray], dict[str, object]]]

Adapter wiring periodic-orbit families to continuation backends.

create_problem(*, domain_obj, config)

Create a continuation problem.

Parameters:

• domain_obj (PeriodicOrbit) – The domain object to continue.

• config (_OrbitContinuationConfig) – The configuration for the continuation problem.

Returns:

The continuation problem.

Return type:

_ContinuationProblem

to_backend_inputs(problem)

Convert the continuation problem to backend inputs.

Parameters:

problem (_ContinuationProblem) – The continuation problem.

Returns:

The backend inputs.

Return type:

_BackendCall

to_domain(outputs, *, problem)

Convert the continuation outputs to a domain object.

Parameters:

• outputs (tuple[list[np.ndarray], dict[str, object]]) – The continuation outputs.

• problem (_ContinuationProblem) – The continuation problem.

Returns:

The domain object.

Return type:

dict[str, object]

to_results(outputs, *, problem, domain_payload=None)

Convert the continuation outputs to a results object.

Parameters:

• outputs (tuple[list[np.ndarray], dict[str, object]]) – The continuation outputs.

• problem (_ContinuationProblem) – The continuation problem.

• domain_payload (Any, optional) – The domain payload.

Returns:

The results object.

Return type:

ContinuationResult
