Next we construct the equivalence class graph of G. Withoutabox Submit to Film Festivals. For the sake of simplicity, consider an ordering of the elements of V G such that each equivalence class of R is a set of consecutive elements in that ordering; for instance first we consider the vertices of X1then the vertices of X2 and so on until we reach the vertices of the last class Xp.
