Summary: A bipartite graph is biplanar if the vertices can be placed on two parallel lines in the plane such that there are no edge crossings when edges are drawn as straight-line segments. We study two problems:
– 2-Layer Planarization: can $$k$$ edges be deleted from a given graph $$G$$ so that the remaining graph is biplanar?
– 1-Layer Planarization: same question, but the order of the vertices on one layer is fixed.
For the entire collection see [Zbl 1069.68013].
