En 20th European Workshop on Computational Geometry, Sevilla.http://hdl.handle.net/11441/55055Let G = (V, E) be a graph with n vertices and let P be a set of n points in the plane. We show that deciding whether there is a planar straight-line embedding of G such that the vertices V are embedded onto the points P is NP-complete, even when G is 2-connected and 2-outerplanar. This settles an open problem posed in [P. Bose. On embedding an outer-planar graph in a point set. Comput. Geom. Theory Appl., 23:303-312, November 2002.
