Summary: In this paper, an optimization problem on a Riemannian manifold \(M\) is discussed, and a \(\varepsilon\)-subgradient algorithm for the problem is proposed. Provided that the manifold \(M\) is complete and has non-negative sectional curvature, some convergence results of the infinite sequence generated by the algorithm are proved.
