It is known that, for any fixed ., any geometric graph . on n vertices with no . pairwise crossing edges contains at most .(. log .) edges. In this paper we give a new, simpler proof of this bound, and show that the same bound holds also when the edges of . are represe

A polyhedral approach to the multi-layer crossing minimization problem,f the multi-layer crossing minimization problem, we examine the 2-layer case and derive several classes of facets of the associated polytope. Preliminary computational results for 2- and 3-layer instances indicate, that the usage of the corresponding facet-defining inequalities in a branch-and-cut a

On embedding an outer-planar graph in a point set,ght-line embedding of . in ., improving upon the algorithm in [GMPP91, CU96] that requires .(..) time. Our algorithm is near-optimal as there is an .(. log .) lower bound for the problem [BMS95]. We present a simpler .(.) time and .(.) space algorithm to compute a straight-line embedding of . in . w

Three-dimensional grid drawings of graphs, of . are pairwise non-crossing. It is shown that for any fixed . ≥ 2, every .-colorable graph of . vertices has a three-dimensional grid drawing that fits into a box of volume .(..). The order of magnitude of this bound cannot be improved.
