The $\mathcal{G}$-width of a class of graphs $\mathcal{G}$ is defined as follows. A graph G has $\mathcal{G}$-width k if there are k independent sets ℕ1,...,ℕk in G such that G can be embedded into a graph $H \in \mathcal{G}$ such that for every edge e in H which is not an edge in G, there exists an i such that both endpoints of e are in ℕi. For the class $\mathfrak{C}$ of cographs we show that $\mathfrak{C}$-width is NP-complete. We show that the recognition is fixed-parameter tractable, and we show that there exists a finite obstruction set. We introduce simple-width as an alternative for rankwidth and we characterize the graphs with simple-width at most two.
