WebTo develop optimization algorithms, we need local parameterizations of the manifold, of which many are available. A local parametrization corresponds to a local flattening/straightening of the manifold, a local deformation of the manifold to arrive at a subset of a Euclidean space. A desirable deformation is one that, informally speaking ...
