Geometric algorithms and combinatorial optimization by Martin Grötschel( Book )

35 editions published between 1980 and 2012 in English and German and held by 592 WorldCat member libraries worldwide

This book develops geometric techniques for proving the polynomial time solvability of problems in convexity theory, geometry, and - in particular - combinatorial optimization. It offers a unifying approach based on two fundamental geometric algorithms: - the ellipsoid method for finding a point in a convex set and - the basis reduction method for point lattices. The ellipsoid method was used by Khachiyan to show the polynomial time solvability of linear programming. The basis reduction method yields a polynomial time procedure for certain diophantine approximation problems. A combination of these techniques makes it possible to show the polynomial time solvability of many questions concerning poyhedra - for instance, of linear programming problems having possibly exponentially many inequalities. Utilizing results from polyhedral combinatorics, it provides short proofs of the poynomial time solvability of many combinatiorial optimization problems. For a number of these problems, the geometric algorithms discussed in this book are the only techniques known to derive polynomial time solvability. This book is a continuation and extension of previous research of the authors for which they received the Fulkerson Prize, awarded by the Mathematical Programming Society and the American Mathematical Society

Online optimization of large scale systems by Martin Grötschel( Book )

10 editions published between 2001 and 2010 in English and held by 178 WorldCat member libraries worldwide

Whether costs are to be reduced, profits to be maximized, or scarce resources to be used wisely, optimization methods are available to guide decision making. In online optimization the main issue is: incomplete data; and the scientific challenge: How well can an online algorithm perform? Can one guarantee solution quality, even without knowing all data in advance? In real-time optimization there is an additional requirement, decisions have to be computed very fast, fast in relation to the time frame of the instance we consider. Online and real-time optimization problems occur in all branches of optimization: linear, nonlinear, integer, stochastic. These areas have developed their own techniques but they are addressing the same issues: quality, stability, and robustness of the solutions. To fertilize this emerging topic of optimization theory and to foster cooperation between the different branches of optimization, the Deutsche Forschungsgemeinschaft (DFG) has supported a Priority Programme "Online Optimization of Large Systems". This volume contains "background articles" and "research articles". Background articles are intended to give an overview over the basic theory in the respective area and are accessible to graduate math students. Research articles summarize the progress in a project achieved in the Priority Programme
The sharpest cut : the impact of Manfred Padberg and his work by Martin Grötschel( Book )

10 editions published in 2004 in English and held by 108 WorldCat member libraries worldwide

This title is written in honor of Manfred Padberg, who has made fundamental contributions to both the theoretical and computational sides of integer programming and combinatorial optimization. This outstanding collection presents recent results in these areas that are closely connected to Padberg's research. His deep commitment to the geometrical approach to combinatorial optimization can be felt throughout this volume; his search for increasingly better and computationally efficient cutting planes gave rise to its title. The peer-reviewed papers contained here are based on invited lectures given at a workshop held in October 2001 to celebrate Padberg's 60th birthday. Grouped by topic (packing, stable sets, and perfect graphs; polyhedral combinatorics; general polytopes; semidefinite programming; computation), many of the papers set out to solve challenges set forth in Padberg's work. The book also shows how Padberg's ideas on cutting planes have influenced modern commercial optimization software

Packing Steiner Trees : a cutting plane algorithm and computational results by Martin Grötschel( Book )

18 editions published between 1992 and 1994 in 3 languages and held by 33 WorldCat member libraries worldwide

Abstract: "In this paper we investigate separation problems for classes of inequalities valid for the polytope associated with the Steiner tree packing problem, a problem that arises, e.g., in VLSI routing. The separation problem for Steiner partition inequalities is NP-hard in general. We show that it can be solved in polynomial time for those instances that come up in switchbox routing. Our algorithm uses dynamic programming techniques. These techniques are also applied to the much more complicated separation problem for alternating cycle inequalities. In this case we can compute in polynomial time, given some point y, a lower bound for the gap [alpha] - a[superscript T]y over all alternating cycle inequalities a[superscript T]x [> or =] [alpha]. This gives rise to a very effective separation heuristic. A by-product of our algorithm is the solution of a combinatorial optimization problem that is interesting in its own right: Find a shortest path in a graph where the 'length' of a path is its usual length minus the length of its longest edge."

Facets of combinatorial optimization : Festschrift for Martin Grötschel by M Jünger( Book )

3 editions published in 2013 in English and held by 16 WorldCat member libraries worldwide

Martin Grötschel is one of the most influential mathematicians of our time. He has received numerous honors and holds a number of key positions in the international mathematical community. He celebrated his 65th birthday on September 10, 2013. Martin Grötschel's doctoral descendant tree 1983-2012, i.e., the first 30 years, features 39 children, 74 grandchildren, 24 great-grandchildren, and 2 great-great-grandchildren, a total of 139 doctoral descendants. This book starts with a personal tribute to Martin Grötschel by the editors (Part I), a contribution by his very special "predecessor" Manfred Padberg on "Facets and Rank of Integer Polyhedra" (Part II), and the doctoral descendant tree 1983-2012 (Part III). The core of this book (Part IV) contains 16 contributions, each of which is coauthored by at least one doctoral descendant. The sequence of the articles starts with contributions to the theory of mathematical optimization, including polyhedral combinatorics, extended formulations, mixed-integer convex optimization, superclasses of perfect graphs, efficient algorithms for subtree-telecenters, junctions in acyclic graphs, and preemptive restricted strip covering, as well as efficient approximation of non-preemptive restricted strip covering. Combinations of new theoretical insights with algorithms and experiments deal with network design problems, combinatorial optimization problems with submodular objective functions, and more general mixed-integer nonlinear optimization problems. Applications include VLSI layout design, systems biology, wireless network design, mean-risk optimization, and gas network optimization. Computational studies include a semidefinite branch and cut approach for the max k-cut problem, mixed-integer nonlinear optimal control, and mixed-integer linear optimization for scheduling and routing of fly-in safari planes. The two closing articles are devoted to computational advances in general mixed-integer linear optimization, the first by scientists working in industry, the second by scientists working in academia. These articles reflect the "scientific facets" of Martin Grötschel who has set standards in theory, computation, and applications -- P.4 of cover

Optimization of transportation systems by Ralf Borndörfer( Book )

5 editions published in 1998 in English and held by 12 WorldCat member libraries worldwide

Abstract: "The world has experienced two hundred years of unprecedented advances in vehicle technology, transport system development, and traffic network extension. Technical progress continues but seems to have reached some limits. Congestion, pollution, and increasing costs have created, in some parts of the world, a climate of hostility against transportation technology. Mobility, however, is still increasing. What can be done? There is no panacea. Interdisciplinary cooperation is necessary, and we are going to argue in this paper that Mathematics can contribute significantly to the solution of some of the problems. We propose to employ methods developed in the Theory of Optimization to make better use of resources and existing technology. One way of optimization is better planning. We will point out that Discrete Mathematics provides a suitable framework for planning decisions within transportation systems. The mathematical approach leads to a better understanding of problems. Precise and quantitative models, and advanced mathematical tools allow for provable and reproducible conclusions. Modern computing equipment is suited to put such methods into practice. At present, mathematical methods contribute, in particular, to the solution of various problems of operational planning. We report about encouraging results achieved so far."
Online dispatching of automobile service units in real-time by Martin Grötschel( Book )

4 editions published in 2002 in English and held by 11 WorldCat member libraries worldwide

Abstract: "Combinatorial online optimization is an area with lots of applications and potential for significant progress, both in theory and in practice. In this short note we sketch the ADAC problem, a typical large-scale online optimization problem, discuss some theoretical and practical issues coming up, and explain, very briefly, how we approach this problem mathematically. Online problems are a battlefield of heuristics with many strong claims about their solution quality. We indicate that a stronger problem orientation and the use of a little more mathematics may yield."
Public transport to the fORe! by Ralf Borndörfer( Book )

3 editions published in 2005 in English and held by 11 WorldCat member libraries worldwide

Abstract: "Can OR methods help the public transport industry to break even? How would you build a public transport system? For example, have a look at Berlin. The BVG, Berlin's public transport company, maintains a network of 2,423 km, operates 197 lines with 3,286 stops, using 1,554 busses, 1,391 subway cars, and 599 trams from 12 depots, and has 13,409 employees [7]. The BVG currently transports about 800 million passengers per year and covers about 40% of the total non-pedestrian traffic volume of the city [18]. Does Berlin have a 'reasonable' public transportation network? Does the BVG run a 'good' transportation system? Is it 'efficient'? These are difficult questions. In fact, politicians, transportation managers, customers, taxpayers, etc., frequently employ judgements such as "good" and "efficient", but nobody can give a definition what this exactly means. Since almost every public transportation system in the world is in the red, the cheapest system is no public transportation at all. On the other hand, the most convenient system for the passenger -- a stop in front of every house with direct connections to everywhere -- is much to expensive. What is the right compromise? Operations Research has no good answer either -- so far. But OR can improve aspects of public transportation significantly, as we want to demonstrate in the following."
Solving the asymmetric travelling salesman problem with time windows by branch-and-cut by Norbert Ascheuer( Book )

5 editions published in 1999 in English and held by 11 WorldCat member libraries worldwide

Abstract: "Many optimization problems have several equivalent mathematical models. It is often not apparent which of these models is most suitable for practical computation, in particular, when a certain application with a specific range of instance sizes is in focus. Our paper addresses the Asymmetric Travelling Salesman Problem with time windows (ATSP-TW) from such a point of view. The real-world application we aim at is the control of a stacker crane in a warehouse. We have implemented codes based on three alternative integer programming formulations of the ATSP-TW and more than ten heuristics. Computational results for real-world instances with up to 233 nodes are reported, showing that a new model presented in a companion paper outperforms the other two models we considered -- at least for our special application -- and that the heuristics provide acceptable solutions."
