CORC REPORT 2003 - 01 Set covering problems and Chvátal - Gomory cuts ∗
Consider a 0/1 integer program min{c T x : Ax ≥ b, x ∈ {0, 1} n } where A is nonnegative. We show that if the number of minimal covers of Ax ≥ b is polynomially bounded, then there is a polynomially large relaxation whose value is arbitrarily close to being at least as good as that given by the rank-r closure, for any fixed r. A special case of this result is that given by set-covering problems...
متن کاملTrade-offs getting tougher: problems paying medical bills increase for U.S. families, 2003-2007.
About 57 million Americans were in families with problems paying medical bills in 2007--an increase of 14 million people since 2003, according to a new national study by the Center for Studying Health System Change (HSC). Problems paying medical bills increased for both nonelderly insured and uninsured people. Although the rate of medical bill problems is much higher for uninsured people, most ...
متن کاملAiaa 2003–3692 Choice of Variables and Preconditioning for Time Dependent Problems
We consider the use of low speed preconditioning for time dependent problems. These are solved using a dual time step approach. We consider the effect of this dual time step on the parameter of the low speed precondi-tioning. In addition, we compare the use of two sets of variables, conservation and primitive variables, to solve the system. We show the effect of these choices on both the conver...
متن کاملSolving Hard Mixed-Integer Programming Problems with Xpress-MP: A MIPLIB 2003 Case Study
Over the past decade there has been a huge improvement in the performance of state-of-the-art MIP codes. Combined with the increased performance of computers over this period the size and complexity of the problems that can be solved has increased enormously. In this paper we take a closer look at some of the hardest problems in the MIPLIB 2003 library ([4]) to show how much progress has been m...
متن کاملRoboCup 2003
The GermanTeam is a joint project of several German universities in the Sony Legged Robot League. This report describes the software developed for the RoboCup 2003 in Padova. It presents the software architecture of the system as well as the methods that were developed to tackle the problems of motion, image processing, object recognition, self-localization, and robot behavior. The approaches f...
