In this paper we present several powerful techniques which allow us to generate efficiently channel routing solutions which are beneficial to further compaction. Our techniques can be applied to straight track compaction as well as to contour routing compaction, and produce very encouraging results. In particular, for Deutsch's Difficult Example, we obtained a straight track routing solution whose area is 7% less than the best known result after straight track compaction. Our router also generated a routing solution which leads to a very satisfactory result after contour routing compaction.
