We investigate the approximability of minimum and maximum linear ordering problems (MIN-LOP and MAX-LOP) and related feedback set problems such as maximum weight acyclic subdiagraph (MAX-W-SUBDAG), minimum weight feedback arc/vertex set (MIN-W-FAS/ MIN-W-FVS) and a generalization of the latter calle

β¦ Synopsis
We consider approximations of the form n 1ΓoΓ°1Γ for the Maximum Clique problem, where n is the number of vertices in the input graph and where the ''oΓ°1Γ'' term goes to zero as n increases. We show that sufficiently strong negative results for such problems, which we call strong inapproximability results, have interesting consequences for exact computation. A simple sampling method underlies most of our results.

We study the approximability of some problems which aim at finding spanning trees in undirected graphs which maximize, rather than minimize, a single objective function representing a form of benefit or usefulness of the tree. We prove that the problem of finding a spanning tree which maximizes the
## Contact graphs are a special kind of intersection graphs of geometrical objects in which the objects are not allowed to cross but only to touch each other. Contact graphs of simple curves, and line segments as a special case, in the plane are considered. The curve contact representations are st
