In a fully asynchronous message-passing distributed system, in which at least one process may have a crash failure, it has been proven in the famous 1985 FLP impossibility result by Fischer, Lynch and Paterson that a deterministic algorithm for achieving consensus is impossible. [5] See more A fundamental problem in distributed computing and multi-agent systems is to achieve overall system reliability in the presence of a number of faulty processes. This often requires coordinating processes to reach … See more Three agreement problems of interest are as follows. Terminating Reliable Broadcast A collection of $${\displaystyle n}$$ processes, numbered from $${\displaystyle 0}$$ to $${\displaystyle n-1,}$$ communicate by … See more To solve the consensus problem in a shared-memory system, concurrent objects must be introduced. A concurrent object, or shared object, is a data structure which helps concurrent processes communicate to reach an agreement. Traditional … See more The consensus problem requires agreement among a number of processes (or agents) for a single data value.
