WebJul 25, 2024 · Lower bound (L (n)) is a property of the specific problem i.e. the sorting problem, matrix multiplication not of any particular algorithm solving that problem. Lower bound theory says that no algorithm can do the job in fewer than that of (L (n)) times the units for arbitrary inputs i.e. that for every comparison based sorting algorithm must ... WebIn the smooth and non-convex stochastic regime, this paper establishes a lower bound for distributed algorithms whether using unbiased or contractive compressors in unidirection or bidirection. To close the gap between this lower bound and the best existing upper bound, we further propose an algorithm, NEOLITHIC, that almost reaches our lower ...
