Abstract
We give a new randomizedalgorithmfor achieving consensus among
asynchronous processes that communicatebyreadingandwriting shared
registers. The fastest previously known algorithm has exponential ex-
pected running time. Our algorithm is polynomial, requiring an ex-
pected O(n4) operations. Applications of this algorithm include the
eliminationof critical sections from concurrent data structures and the
construction of asymptotically unbiased shared coins.
