Example text

The calculation of CM (z) at a specific z is the computation of one max-h-route flow value. By the algorithm in [5], we can compute the flow value in O(hmn). Hence, it takes O(h2 mn) to find all breaking points of CM . Similar to Sect. 3, we can calculate CM (z) for a specific z from the set of breaking points obtained from ES algorithm. Assume that the set is {(ε0 , CM (ε0 )) , . . , (εq , CM (εq ))}. The calculation can be done as follows. ⎨ z−λi z εi+1 (CM (εi+1 ) − CM (εi )) λi+1 −λi , for εi CM (z) = CM (εq ), for z εq 6 Conclusion and Future Works When we tune parameters in our network, the conventional way to evaluate each parameter value is the amount of max-flow.

Rnn−1 0 Proof. Let G = (C ∈ S, E) be a thin headless spider having C = {1, . . , n} and S = {n + 1, . . , 2n}. The neighborhood matrix of (C, S) can be written as ⎡ ⎣ EI N [G] = . I I Now, in order to find ∃[G]: (1) If i, j ∈ C, N [i] ∃ N [j] = {i + n, j + n}. (2) If i, j ∈ S, N [i] ∃ N [j] = {i, i − n} ∃ {j, j − n} and are dominated by N [i]. a) If i ∈ C and j ∈ S, j ⇒= i + n, N [i] ∃ N [j] = [C ∈ {i + n})] ∃ {j, j − n} = {j, i + n} ∈ (C − {j − n}) is dominated by N[i]. b) If i ∈ C and j = i + n ∈ S, N [i] ∃ N [j] = [C ∈ {i + n})] ∃ [{i, i + n} = C − {i}.

The capacity of each edge was picked uniformly at random between 0 and 20. 1 is satisfied for all 0 k σ. For a larger graph, we also perform an experiment on the case when |V | = 40, |E| = 160. We also get the similar result for that case, as 98 out of 100 networks are satisfying the equation for all 0 k σ. Since the value of max-MLA-reliable flow and max-MLA-robust flow are equal when the requirement is satisfied, we can also imply from the experimental results that those two values are equal in most of the random networks.
