Integer Programming and Combinatorial Optimization: 4th International IPCO Conference, Copenhagen, Denmark, May 29 - 31, 1995. Proceedings [Paperback]

This volume constitutes the proceedings of the Fourth International Conference on Integer Programming and Combinatorial Optimization, IPCO '95, held in Copenhagen in May 1995 under the sponsorship of the Mathematical Programming Society.
Integer programming and combinatorial optimization provide a fruitful theoretical and algorithmic basis for the solution of a number of optimization problems occuring in real-world situations, such as production planning and scheduling, routing, crew scheduling, or network construction. This volume presents 36 revised papers selected from a total of 105 submissions and offers a representative up-to-date snapshot on the state of the art in this interdisciplinary area of research and applications.Improved approximation algorithms for MAX k-CUT and MAX BISECTION.- Approximating minimum feedback sets and multi-cuts in directed graphs.- Nonlinear formulations and improved randomized approximation algorithms for multicut problems.- Separating clique tree and bipartition inequalities in polynomial time.- The interval order polytope of a digraph.- Separation problems for the stable set polytope.- Computational study of a family of mixed-integer quadratic programming problems.- A minimal algorithm for the Bounded Knapsack Problem.- A framework for tightening 01 programs based on extensions of pure 01 KP and SS problems.- Combining semidefinite and polyhedral relaxations for integer programs.- Distributed near-optimal matching.- The random linear bottleneck assignment problem.- On implementing push-relabel method for the maximum flow problem.- Use of hidden network structure in the set partitioning problem.- Generalized max flows and augmenting paths.- Oriented matroid polytopes and polyhedral fans are signable.- On combinatorial properties of binary spaces.- Coverings and delta-coverings.- The topological structure of maximal lattice free convex bodies: The general case.- The Hilbert basis of the cut cone over the complete graph Kl£ž
