The Traveling Salesman Problem a Computational Study by David L Applegate( )
4 editions published between 2006 and 2011 in English and held by 818 WorldCat member libraries worldwide
This book presents the latest findings on one of the most intensely investigated subjects in computational mathematics--the traveling salesman problem. It sounds simple enough: given a set of cities and the cost of travel between each pair of them, the problem challenges you to find the cheapest route by which to visit all the cities and return home to where you began. Though seemingly modest, this exercise has inspired studies by mathematicians, chemists, and physicists. Teachers use it in the classroom. It has practical applications in genetics, telecommunications, and neuroscience. The autho
Linear programming by Vašek Chvátal( Book )
19 editions published between 1983 and 2003 in English and Undetermined and held by 808 WorldCat member libraries worldwide
Topics on perfect graphs by V Chvtal( Book )
8 editions published in 1984 in English and held by 375 WorldCat member libraries worldwide
The purpose of this book is to present selected results on perfect graphs in a single volume. These take the form of reprinted classical papers, survey papers or new results
Combinatorial Optimization by V Chvátal( )
8 editions published in 2011 in English and held by 262 WorldCat member libraries worldwide
This book is a collection of six articles arising from the meeting of the NATO Advanced Study Institute (ASI) "Combinatorial Optimization: Methods and Applications," which was held at the University of Montreal in June 2006. This ASI consisted of seven series of five one-hour lectures and one series of four one-hour lectures. It was attended by some sixty students of graduate or postdoctoral level from fifteen countries worldwide. It includes topics such as: integer and mixed integer programming, facility location, branching on split disjunctions, convexity in combinatorial optimizat
Recognizing dart-free perfect graphs by Vašek Chvátal( Book )
10 editions published between 1989 and 1992 in 3 languages and held by 17 WorldCat member libraries worldwide
Abstract: "The 'dart' is the graph with vertices a, b, c, d, e and edges ab, ac, ad, ae, bd, cd. We present a polynomial-time algorithm to recognize dart-free perfect graphs. The algorithm is based on a decomposition theorem elucidating the structure of these graphs."

Lecture notes on the new AKS sorting network by Vašek Chvátal( Book )
2 editions published in 1992 in English and held by 5 WorldCat member libraries worldwide
Abstract: "Ajtai, Komlós, and Szemerédi constructed sorting networks with N wires of depth O(log N). They were not concerned with the value of the proportionality constant implicit in the O-notation; subsequently Paterson replaced the O(log N) by c log₂ N with c under 6100. We describe an implementation of a more recent, and as yet unpublished, proposal of Ajtai, Komlós, and Szemerédi, that yields a smaller value of c: for every integer N such that N [> or =] 2⁷⁸ there is a sorting network on N wires whose depth is at most 1830 log₂ N - 58657

Determining the stability number of a graph by Vašek Chvátal( Book )
3 editions published between 1976 and 1977 in English and held by 3 WorldCat member libraries worldwide
Certain rules for deriving upper bounds on the stability number of a graph are formalized. The resulting system is powerful enough to (1) encompass the algorithms of Tarjan's type and (2) provide very short proofs on graphs for which the stability number equals the clique-covering number. However, the main result shows that for almost all graphs with a (sufficiently large) linear number of edges, proofs within the system must have at least exponential length
