Abstract :
A k-EMCTN is obtained by adding k more stages in front of a multistage cube-type network (MCTN). It is shown that a permutation is admissible to a k-EMCTN if and only if the conflict graph is 2k -colorable. For the case k=1, an O(NlgN) algorithm is given for constructing the conflict graph, which leads to an O(NlgN) admissibility algorithm. Furthermore, it is shown that Ω(NlgN) bits must be checked in the binary representation of a permutation for determining its admissibility
