The commons section of the documentation collects common elements used by more than one solver.

Overview

• debug actions that can be used in any solver, including the DebugActionFactory that turns the input array to a debug= keyword of a solver into the corresponding concrete debugs, especially when passing symbols like :Cost.
• functions that are shared by several solvers.
• objectives, including the decorators that cache, count or embed an objective.
• problems that carry more than a manifold and an objective.
• record actions that can be used in any solver, including the RecordActionFactory that turns the input of a record= keyword into the corresponding concrete records.
• robustifiers used in LevenbergMarquardt to approximate nonsmooth nonlinear least squares.
• states of the sub solvers.
• step sizes that can be used with different solvers in the stepsize= keyword.
• stopping criteria that can be used with different solvers in the stopping_criterion= keyword.
• vector functions to model, for example, constraints.

Passing parameters

Since the overall design of Manopt.jl is modular, one way to set parameters, for example in the objective of a sub problem, is via set_parameter!.
