Lower bounds for sublinear time algorithms
WebNov 29, 2024 · We complement our lower bound by presenting two algorithms that run in strongly sublinear time of . The first algorithm achieves a -approximation; this significantly improves prior close-to-1/2 approximations. Our second algorithm obtains an even better approximation factor of for bipartite graphs. WebConstructing a sublinear time algorithm may seem to be an impossible task since it allows one to read only a small fraction of the input. However, in recent years, we have seen development of sublinear time algorithms for optimization problems arising in such diverse areas as graph theory, geometry, algebraic computations, and computer graphics.
