Webimposed by a given manifold! This is one of the beauties of Riemannian optimization. Because the tangent space is a linear space, optimization in the tangent space does not need to adhere to any constraints. The retraction operation then enforces the constraints of the manifold (e.g. R>R= I;det(R) = 1 ... WebJun 21, 2012 · Abstract: Optimization on manifolds is a rapidly developing branch of nonlinear optimization. Its focus is on problems where the smooth geometry of the search space can be leveraged to design efficient numerical algorithms. In particular, optimization on manifolds is well-suited to deal with rank and orthogonality constraints.
