Question
Prove that there exists no deterministic algorithm that computes the number of processes and that is correct for all anonymous networks of diameter at most two.Hint: exploit the symmetry in the networks of Figure 6.21.
Step 1
21. This network consists of four processes connected in a cycle. Since the network has diameter two, each process can only see its two neighbors. Now, let's assume that there exists a deterministic algorithm that can compute the number of processes in any Show more…
