Bounds for Nonadaptive Group Tests to Estimate the Amount of Defectives,. In this paper we prove that Ω(log.) tests are really needed. The proof is based on an analysis of the influence of tests on the searcher’s ability to distinguish between any two candidate numbers with a constant ratio. Once we know this lower bound, the next challenge is to get optimal constant fa

An Improved Approximation Algorithm for Spanning Star Forest in Dense Graphs,n .-dense graphs within a factor of 1 − . is .-hard. We then demonstrate that for weighted versions (both node- and edge- weighted) of this problem, we cannot get . approximation algorithm with strictly better performance guarantee in .-dense graphs than that of the best possible approximation algor

Fast Edge-Searching and Related Problems,problem of computing node search numbers to the problem of computing fast edge-search time or fast search numbers. Using these relations, we prove that the problem of deciding, given a graph . and an integer ., whether the fast (edge-)search number of . is less than or equal to . is NP-complete; and
