Researchers have developed a novel support-set algorithm designed to efficiently solve optimization problems with nonnegative and orthogonal constraints. This algorithm leverages the property that the global solution of subproblems can be computed in closed form, significantly improving computational efficiency. The proposed method ensures the feasibility of iterates and adjusts the placement of nonzero entries through a strategic update scheme for support sets. Convergence to a first-order stationary point is established, with an iteration complexity of $O(\epsilon^{-2})$ for reaching an $\epsilon$-approximate first-order stationary point. Numerical results indicate strong performance in applications such as nonnegative PCA, clustering, and community detection. AI
