Approximations for Aligned Coloring and Spillage Minimization in Interval and Chordal Graphspilers and have recently been proven NP-Hard. We provide the first constant approximations: a .-approximation for interval graphs and a .-approximation for chordal graphs. We extend our techniques to the problem of minimizing spillage in these graph types.

An Approximation Scheme for Terrain Guardinggorithm is a local search algorithm inspired by the recent results of Chan and Har-Peled and Mustafa and Ray . Our key contribution is to show the existence of a planar graph that appropriately relates the local and global optimum.

Structure Theory for p.m.p. Actionsaxation for UFP on paths that has an integrality gap of .(log..); previously there was no relaxation with .(.) gap. We also consider UFP in general graphs and CPIPs without the no-bottleneck assumption and obtain new and useful results.

I. P. Cornfeld,S. V. Fomin,Ya. G. Sinai loser-independent algorithms can be employed as sub-procedures in a greedy iterative packing approach while preserving monotonicity. A greedy iterative approach provides a good approximation in the context of maximizing a non-decreasing submodular function subject to independence constraints. Our f
