Efficient C-Planarity Testing for Embedded Flat Clustered Graphs with Small Faces
Vol. 13, no. 3, pp. 349-378, 2009. Regular paper.
Abstract Let C be a clustered graph and suppose that the planar embedding of its underlying graph is fixed. Is testing the c-planarity of C easier than
in the variable embedding setting? In this paper we give a first contribution towards answering the above question. Namely, we characterize
c-planar embedded flat clustered graphs with at most five vertices per face and give an efficient testing algorithm for such graphs. The results
are based on a more general methodology that sheds new light on the c-planarity testing problem.
