Abstract

Given a reliable tree network  containing  vertices where each edge has an independent operational probability, this paper presents finding a reliable subtree with at most leaves and with a diameter of at most  which maximizes the expected number of nodes that are reachable from the selected subtree by operational paths. An efficient algorithm is presented for finding a reliable tree core of. Numerical example is explained to clarify the efficient algorithm.
