Manopt v0.5.20

Added

a DebugWarnIfStepsizeCollapsed DebugAction and a related :WarnStepsize symbol for the debug dictionary. This is to be used in conjunction with the ProximalGradientMethodBacktracking stepsize to warn if the backtracking procedure of the proximal_gradient_method hit the stepsize length threshold without converging.

Changed

bumped dependencies.

Fixed

Fixed a few typos in the docs.

Manopt v0.5.19

Diff since v0.5.18

Added

a function get_differential and get_differential_function for first order objectives.
a ParentEvaluationType to indicate that a certain objective inherits it evaluation from the parent (wrapping) objective
a new AllocatingInplaceEvaluation that is used for the functions that offer both variants simultaneously.
a differential= keyword for providing a faster way of computing inner(M, p, grad_f(p), X), introduced to the algorithms conjugate_gradient_descent, gradient_descent, Frank_Wolfe_method, quasi_Newton

Changed

the ManifoldGradientObjective and the ManifoldCostGradientObjective are now merely a const special cases of the ManifoldFirstOrderObjective, since this type might now also represent a differential or other combinations of cost, grad, and differential, where they are computed together.
the AbstractManifoldGradientObjective is renamed to AbstractManifoldFirstOrderObjective, since the second function might now also represent a differential.

Fixed

fixes a small bug where calling mesh_adaptive_direct_search with a start point in some cases did not initialise the state correctly with that start point.
The HestenesStiefelCoefficient now also always returns a real value, similar the other coefficient rules. To the best of our knowledge, this might have been a bug previously.

Introduce a StopWhenRepeated stopping criterion that stops when the given stopping criterion has indicated to stop n times (consecutively, if consecutive=true).
Introduce a StopWhenCriterionWithIterationCondition stopping criterion that stops when a given stopping criterion has been satisfied together with a certain iteration condition. This can the generated even with shortcuts like sc > 5
Introduce a DebugCallback that allows to add a callback function to the debug system
Introduce a callback= keyword to all solvers.
Added back functions estimate_sectional_curvature, ζ_1, ζ_2, close_point from convex_bundle_method; the function call can stay the same as before since there is a curvature estimation fallback
Add back some fields and arguments such as p_estimate, ϱ, α, from ConvexBundleMethodState

This breaking release is mainly concerned with stability and usability

all interfaces have been unified, especially orders of arguments and names of keywords
for gradient rules like CG or average gradient, and stepsizes like the Armijo linesearch, specifying the manifold (yet again) is no longer necessary thanks to an idea from Dmtry
the documentation has been reworked to using a glossary internally
we now use Aqua.jl to avoid ambiguities
we are back to supporting Julia 1.6 again after this rework as well.

For a full list of breaking changes see the Changelog.md.

Introduce a ConstrainedManoptProblem to model different ranges for the gradients in the new VectorGradientFunctions beyond the default NestedPowerRepresentation
introduce a VectorHessianFunction to also model that one can provide the vector of Hessians to constraints
introduce a more flexible indexing beyond single indexing, to also include arbitrary ranges when accessing vector functions and their gradients and hence also for constraints and their gradients.

Changed

Remodel ConstrainedManifoldObjective to store an AbstractManifoldObjective internally instead of directly f and grad_f, allowing also Hessian objectives therein and implementing access to this Hessian
Fixed a bug that Lanczos produced NaNs when started exactly in a minimizer, since we divide by the gradient norm.

Quasi-Newton direction update rules are now initialized upon start of the solver with the new internal function initialize_update!.

Fixed

ALM and EPM no longer keep a part of the quasi-Newton subsolver state between runs.

Changed

Quasi-Newton solvers: :reinitialize_direction_update is the new default behavior in case of detection of non-descent direction instead of :step_towards_negative_gradient. :step_towards_negative_gradient is still available when explicitly set using the nondescent_direction_behavior keyword argument.

Added

introduce a feature-based list of solvers and reduce the details in the alphabetical list
adds a PolyakStepsize
added a get_subgradient for AbstractManifoldGradientObjectives since their gradient is a special case of a subgradient.

Fixed

get_last_stepsize was defined in quite different ways that caused ambiguities. That is now internally a bit restructured and should work nicer. Internally this means that the interims dispatch on get_last_stepsize(problem, state, step, vars...) was removed. Now the only two left are get_last_stepsize(p, s, vars...) and the one directly checking get_last_stepsize(::Stepsize) for stored values.
we accidentally exported set_manopt_parameter!, this is now fixed.

Changed

get_manopt_parameter and set_manopt_parameter! have been revised and better documented, they now use more semantic symbols (with capital letters) instead of direct field access (lower letter symbols). Since these are not exported, this is considered an internal, hence non-breaking change.
- semantic symbols are now all nouns in upper case letters

RecordWhenActive to allow records to be deactivated during runtime, symbol :WhenActive
RecordSubsolver to record the result of a subsolver recording in the main solver, symbol :Subsolver
RecordStoppingReason to record the reason a solver stopped
made the RecordFactory more flexible and quite similar to DebugFactory, such that it is now also easy to specify recordings at the end of solver runs. This can especially be used to record final states of sub solvers.

Changed

being a bit more strict with internal tools and made the factories for record non-exported, so this is the same as for debug.

Fixed

The name :Subsolver to generate DebugWhenActive was misleading, it is now called :WhenActive – referring to “print debug only when set active, e.g. by the parent (main) solver”.
the old version of specifying Symbol => RecordAction for later access was ambiguous, since it could also mean to store the action in the dictionary under that symbol. Hence the order for access was switched to RecordAction => Symbol to resolve that ambiguity.

Introduce a Pair-based format to add elements to these hooks, while all others ar now added to :Iteration (no longer to :All)
(planned) add an easy possibility to also record the initial stage and not only after the first iteration.

Changed

Changed the symbol for the :Step dictionary to be :Iteration, to unify this with the symbols used in recording, and removed the :All symbol. On the fine granular scale, all but :Start debugs are now reset on init. Since these are merely internal entries in the debug dictionary, this is considered non-breaking.
introduce a StopWhenSwarmVelocityLess stopping criterion for particle_swarm replacing the current default of the swarm change, since this is a bit more effective to compute

Fixed

Doc strings now follow a vale.sh policy. Though this is not fully working, this version however improves a lot of the doc strings concerning wording and spelling.
