Optimization Algorithm on Riemannian Manifolds.

Code Style: Blue CI codecov Aqua QA

DOI DOI

For a function $f: ℳ → ℝ$ that maps from a Riemannian manifold ℳ to the real line, this package aims to solve

Find the minimizer p on ℳ, that is, the (or a) point where f attains its minimum.

Manopt.jl provides

  • A framework to implement arbitrary optimization algorithms on Riemannian Manifolds
  • A library of optimization algorithms on Riemannian manifolds
  • an easy-to-use interface for (debug) output and recording values during an algorithm run.
  • several tools to investigate the algorithms, gradients, and optimality criteria

Getting started

In Julia you can get started by just typing

using Pkg; Pkg.add("Manopt");

and then checkout the Get started: optimize! tutorial.

Related packages

Manopt.jl is based on ManifoldsBase.jl, hence the algorithms can be used with any manifold following this interface for defining a Riemannian manifold.
