The algorithm to insert an edgeein linear time into a planar graphGwith a minimal number of crossings one[10], is a helpful tool for designing heuristics that minimize edge crossings in drawings of general graphs. Unfortunately, some graphs do not have a geometric embeddingsuch thathas the same number of crossings as the embedding. This motivates the study of the computational complexity of the following problem: Given a combinatorially embedded graphG, compute a geometric embeddingthat has the same combinatorial embedding asGand that minimizes the crossings of. We give polynomial-time algorithms for special cases and prove that the general problem is fixed-parameter tractable in the number of crossings. Moreover, we show how to approximate the number of crossings by a factor, whereis the maximum vertex degree ofG.
