WebAbstract. Recent advances in distributed optimization and learning have shown that communication compression is one of the most effective means of reducing communication. While there have been many results for convergence rates with compressed communication, a lower bound is still missing.Analyses of algorithms with communication … WebJun 24, 2024 · 1. Actually, you don't need a SAT solver; the SHA-256 hash compression function is h c ( s t a t e, m e s s a g e) = s t a t e ⊕ E m e s s a g e ( s t a t e), for an easily invertible (if you know the message) E. All you need to do is take your arbitrary message block and find the state for which 0 = E m e s s a g e ( s t a t e) – poncho.
