Orthogonal-Ordering Constraints are Tough
Vol. 17, no. 1, pp. 1-10, 2013. Concise paper.
Abstract We show that rectilinear graph drawing, the core problem of bend-minimum orthogonal graph drawing, and uniform edge-length drawing, the core problem of force-directed placement, are NP-hard even for embedded paths if subjected to orthogonal-ordering constraints.
