TY - JOUR ID - 722628 AU - Hliněný, Petr - Salazar, Gelasio PY - 2007 TI - Approximating the Crossing Number of Toroidal Graphs PB - Springer Verlag CY - Berlin SN - 9783540771180 KW - crossing number KW - crossing minimization KW - approximation UR - http://www.nishizeki.ecei.tohoku.ac.jp/isaac07/ N2 - CrossingNumber is one of the most challenging algorithmic problems in topological graph theory, with applications to graph drawing and VLSI layout. No polynomial time constant approximation algorithm is known for this NP-complete problem. We prove that a natural approach to planar drawing of toroidal graphs (used already by Pach and T\'oth) gives a polynomial time constant approximation algorithm for the crossing number of toroidal graphs with bounded degree. In this proof we present a new ``grid'' theorem on toroidal graphs. ER -
