US2016 also includes the geographical location of these followers, the number of their own followers and, very im...

ii non–deterministic event occurs, a new state interval is started. I study replica organization under this computation model (semi–active replication). In this model, all non–deterministic decisions are made on one distinguished replica (the leader), while all other replicas (the followers) are forced to follow the same sequence of non–deterministic events.
