Chang-roberts algorithm example
WebAlgorithm is pretty simple: Some process P notes a lack of the leader and initiates the election. It creates election message and send it to the next process in the ring. P sends … WebFor example, if the goal is to compute the spanning tree of the network, one can simply apply one of the well-known algorithms proposed by Kruskal or Prim. However, in a …
