... approach, which is also called RDS, is based on 0.97 randomized algorithms. Contrary to the coordination 0.96 algorithms in distributed systems, the RDS imposes no further load to the system. Furthermore, it is very simple and 0.95 easily implementable. We have shown the efficiency of the 0.94 RDS through statistical analysis. In ...
