WebThe Byzantine agreement problem is to devise an algorithm so that nprocessors, each with a private input can agree on a single common output that is equal to some processor’s input. For example, if all processors start with 1, they must all decide on 1. The processors should successfully terminate despite the presence of t= ( n) bad processors. WebThus far, however, reaching Byzantine agreement has required either many rounds of communication (i.e., messages had to be sent back and forth a number of times that grew … high-speed rails https://numbermoja.com

WebThe simplest good algorithm for Byzantine Agreement with reliability t is optimal with respect to time for immediate agreement (t+l phases). Though its0(n2)message requirement is not optimal, we discuss it here because it establishes the feasibility of actually implementing algorithms for Byzantine Agreement with reliability greater than 1. WebJul 25, 2016 · For the Byzantine fault-tolerant optimization problem, the ideal goal is to optimize the average of local cost functions of the non-faulty agents. However, this goal also cannot be achieved. Therefore, we consider a relaxed version of the fault-tolerant optimization problem.
