Such an orientation-constrained layout, if it exists, may be constructed in polynomial time, and all orientation-constrained layouts may be listed in polynomial time per layout.To appear at Algorithms and Data Structures Symposium, Banff, Canada, August 2009. 12 pages, 5 figuresComputational GeometryF.2.2text
