“…Hence, in this chapter we try to focus on selected related work and recent coordinate free techniques that have not yet been covered by these papers. There are further methods like space-filling curves [130,131,76,149], methods that handle graphs having geometrical information [22,76,82,119,134], simulated annealing [92] and ant-colony optimization [103,44] or parallel approaches to graph partitioning [94,167,164,41,42,87,136] which are not discussed here. Moreover, at this place we restrict ourselves to the techniques that we did not integrate into our systems or only present an abstract view.…”
