Minimum Certificate Dispersal with Tree Structures

Given an n-vertex graph G = (V,E) and a set R ⊆ {{x, y} | x, y ∈ V } of requests, we consider to assign a set of edges to each vertex in G so that for every request {u, v} in R the union of the edge sets assigned to u and v contains a path from u to v. The Minimum Certificate Dispersal Problem (MCD) is defined as one to find an assignment that minimizes the… CONTINUE READING
