Excerpt from Branch and Bound Methods for Combinatorial Problems The difficulty of the problem is entirely computational since the number of tours (i.e. Feasible solutions) is finite. Enumeration of all tours, however, would be a discouraging process for a problem of any appreciable size. There are (n-l)! Tours. Doubling the size of a problem from 5 to 10 cities multiples the number of tours by about 15 thousand; doubling from 10 to 20 cities, by about 250 billion. To put the branch and bound algorithm in perspective, we report briefly on other approaches to the traveling salesman problem. Several methods have been developed for finding a good but not necessarily optimal tour. One of these is random search. Since any permutation of the first n integers can be interpreted as a tour, it is an easy matter to generate a tour by a random process, evaluate its cost, and compare it to the best of any previously developed solutions. Since these steps can be performed quickly, a large number of tours can be generated, and the best one will usually be a good solution. Further more, the statistics generated make it possible to say something about the probability of finding a better solution. This type of approach has been investigated by Heller [8] for a somewhat different problem and in much more detail with more sophisticated random search procedures by Reiter[l6,17]for the traveling salesman problem. On a somewhat similar tack Karg and Thompson[10] have developed a heuristic program. However, their program is designed primarily for the symmetric case. Such approximate methods are important, especially for large* problems. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

This monograph deals with a general class of solution approaches in deterministic global optimization, namely the geometric branch-and-bound methods which are popular algorithms, for instance, in Lipschitzian optimization, d.c. programming, and interval analysis.It also introduces a new concept for the rate of convergence and analyzes several bounding operations reported in the literature, from the theoretical as well as from the empirical point of view. Furthermore, extensions of the prototype algorithm for multicriteria global optimization problems as well as mixed combinatorial optimization problems are considered. Numerical examples based on facility location problems support the theory. Applications of geometric branch-and-bound methods, namely the circle detection problem in image processing, the integrated scheduling and location makespan problem, and the median line location problem in the three-dimensional space are also presented. The book is intended for both researchers and students in the areas of mathematics, operations research, engineering, and computer science.

Dynamic programming is a powerful tool for solving a wide range of optimization problems, from scheduling to resource allocation to network design. This book presents an innovative approach to solving these problems using the branch and bound method, a technique that has typically been used for solving combinatorial problems. With clear explanations, insightful examples, and practical advice, Roy E. Marsten and Thomas L. Morin show how to apply this powerful approach to a variety of dynamic programming problems.

Solving combinatorial optimization problems can often lead to runtime growing exponentially as a function of the input size. But important real-world problems, industrial applications, and academic research challenges, may demand exact optimal solutions. In such situations, parallel processing can reduce the runtime from days or months, typical when one workstation is used, to a few minutes or even seconds. Partners of the CEC-sponsored SCOOP Project (Solving Combinatorial Optimization Problems in Parallel) contributed, on invitation, to this book; much attention was paid to competent coverage of the topic and the style of writing. Readers will include students, scientists, engineers, and professionals interested in the design and implementation of parallel algorithms for solving combinatorial optimization problems.

This tutorial contains written versions of seven lectures on Computational Combinatorial Optimization given by leading members of the optimization community. The lectures introduce modern combinatorial optimization techniques, with an emphasis on branch and cut algorithms and Lagrangian relaxation approaches. Polyhedral combinatorics as the mathematical backbone of successful algorithms are covered from many perspectives, in particular, polyhedral projection and lifting techniques and the importance of modeling are extensively discussed. Applications to prominent combinatorial optimization problems, e.g., in production and transport planning, are treated in many places; in particular, the book contains a state-of-the-art account of the most successful techniques for solving the traveling salesman problem to optimality.

Combinatorial (or discrete) optimization is one of the most active fields in the interface of operations research, computer science, and applied math ematics. Combinatorial optimization problems arise in various applications, including communications network design, VLSI design, machine vision, air line crew scheduling, corporate planning, computer-aided design and man ufacturing, database query design, cellular telephone frequency assignment, constraint directed reasoning, and computational biology. Furthermore, combinatorial optimization problems occur in many diverse areas such as linear and integer programming, graph theory, artificial intelligence, and number theory. All these problems, when formulated mathematically as the minimization or maximization of a certain function defined on some domain, have a commonality of discreteness. Historically, combinatorial optimization starts with linear programming. Linear programming has an entire range of important applications including production planning and distribution, personnel assignment, finance, alloca tion of economic resources, circuit simulation, and control systems. Leonid Kantorovich and Tjalling Koopmans received the Nobel Prize (1975) for their work on the optimal allocation of resources. Two important discover ies, the ellipsoid method (1979) and interior point approaches (1984) both provide polynomial time algorithms for linear programming. These algo rithms have had a profound effect in combinatorial optimization. Many polynomial-time solvable combinatorial optimization problems are special cases of linear programming (e.g. matching and maximum flow). In addi tion, linear programming relaxations are often the basis for many approxi mation algorithms for solving NP-hard problems (e.g. dual heuristics).
