Abstract
A (k, ε) disperser graph G = (V1, V2, E) is a bipartite graph with the property that any subset A is contained as a subset within V1 of cardinality K, the neighbor of A cover at least 1-ε fraction of the vertices of V2. Such graphs have many applications in deramdomization. An explicit construction of (K = 2k, ε) disperser graphs G = (V = [2n], W, E) with an almost optimal degree D = poly(n, ε-1), for every k≥NΩ(1) is extended for any parameter k≤n.
