v0.4.61

Manopt v0.4.61

Diff since v0.4.60

Added

• Tests now also use Aqua.jl to spot problems in the code, e.g. ambiguities.
• 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
  • :active is changed to :Activity
