A Proactive Approach to Reconstructing Overlay Multicast Trees
... For any small ε, δ, which are larger than 0, there exists an N such that with probability greater than 1δ, when the number of points n is larger than N, the length of the longest path in the tree produced by the algorithm is within ε plus the optimal solution. This ε denotes the ratio between the le ...
