Abstract:The report is focused on solving generalized orthogonality constrained optimization problems with differentiable objective functions. By defining the generalized inner product on the tangent space of the generalized orthogonality constrains set, a generalized gradient flow is proposed. It shows that thus generalized gradient flow will be contained on the constraints set if the initial condition is feasible. The week convergence of the generalized gradient flow is given. A discrete iterative scheme is also proposed to make the gradient flow method computable.
