dc.description.abstractIn this paper we look at several well known layout problems. We show that MINCUT layout and Topological bandwidth cannot be approximated unless P=NP, whereas the Maximum linear arrangement problem can be approximated within a constant factor. We also consider some restriction of the MINSUMCUT problem, showing that the problem is in P for, weighted trees, grids without holes and outerplanar graphs. Finally we give a strong indication that graph bisection is as hard to approximate as MINLA.
