String-Averaging Algorithms for Convex Feasibility with Infinitely Many Sets
T. Yung Kong, Homeira Pajoohesh, Gabor T. Herman
Algorithms for convex feasibility find or approximate a point in the intersection of given closed convex sets. Typically there are only finitely many convex sets, but the case of i…
