Flp impossibility result proof by contrary
WebQuestion. I'm reading the FLP impossibility paper.I think I understand the idea of the proof, and I don't have questions about it. However, it seems like the assumption of having at most, a single faulty process is not used in the proof.Put another way, if we remove this assumption and forbid process failure, the proof still seems to hold.

By (inductive use of) Lemma 3.4, any extension of one execution is also a valid extension of the other, and the result will be two indistinguishable executions: every read operation will return the same value in both executions. Thus, outputs in such a pair of executions must be identical. Now the claim

WebIf all nodes were given 0, then we have to agree on 0, and if all nodes were given 1, then we have to agree on 1. Given a set of processors, each with an initial value: All non-faulty processes eventually decide on a value. All processes that decide do so on the same value. The value that has been decided must have proposed by some process. citi statement of understandingWebMar 20, 2024 · Algorithms like Casanova that use such minimal and reasonable network assumptions show that FLP impossibility is not nearly as restrictive as it sounds. … dibs lyrics kelseaWebWhat is Impossibility of FLP. 1.
