We tackle a natural problem from distributed computing, involving time-stamps. Let?={p 1, p
2,…, p N} be a set of computing agents or processes which synchronize with each other from
time to time and exchange information about themselves and others. The gossip problem is
the following: Whenever a set P⊆? meets, the processes in P must decide amongst
themselves which of them has the latest information, direct or indirect, about each agent p in
the system. We propose an algorithm to solve this problem which is finite-state and local …
Summary
 We tackle a natural problem from distributed computing, involving time-stamps. Let ?={p 1, p 2, …, p N } be a set of computing agents or processes which synchronize with each other from time to time and exchange information about themselves and others. The gossip problem is the following: Whenever a set P⊆? meets, the processes in P must decide amongst themselves which of them has the latest information, direct or indirect, about each agent p in the system. We propose an algorithm to solve this problem which is finite-state and local. Formally, this means that our algorithm can be implemented as an asynchronous automaton.
