Manopt.jl Developer guide
This section of the documentation provides an overview on the main abstract types, their ideas and design concepts.
Formerly, these were part of the Plan, which will now sever to host concrete types and properties several solvers have in common, while abstract types, concepts and design ideas will migrate here.
There are two main ingredients of Manopt.jl: The problem and the solver state. The problem represents the task to be solved, which by default includes the manifold an objective is defined on and the objective to solve. The solver's state represents all variables and parameters a solver requires for setup as well as during the iterations.
