This book is concerned with tangent cones, duality formulas, a generalized concept of conjugation, and the notion of maxi-minimizing sequence for a saddle-point problem, and deals more with algorithms in optimization. It focuses on the multiple exchange algorithm in convex programming.

The volume contains new research papers (some of which are of a tutorial nature) on theory and computational methods, oscillatory control, deterministic control of uncertain systems, nonlinear perturbed optimal control, and on control of systems with distributed parameters.

Dieses zweibändige Standardlehrbuch bietet einen umfassenden und aktuellen Überblick über die Numerische Mathematik. Dabei wird besonderer Wert auf solche Vorgehensweisen und Methoden gelegt, die sich durch große Wirksamkeit auszeichnen. Ihr praktischer Nutzen, aber auch die Grenzen ihrer Anwendung werden vergleichend diskutiert. Zahlreiche Beispiele runden dieses unentbehrliche Buch ab.Die Neuauflage des zweiten Bandes wurde vollständig überarbeitet und ergänzt um eine Beschreibung weiterer Techniken im Rahmen der Mehrzielmethode zur Lösung von Randwertproblemen für Gewöhnliche Differentialgleichungen."Das Lehrbuch ... setzt Maßstäbe für eine Numerik-Vorlesung und ist jedem Studenten der angewandten Mathematik zu empfehlen."

Dantzig's development of linear programming into one of the most applicable optimization techniques has spread interest in the algebra of linear inequalities, the geometry of polyhedra, the topology of convex sets, and the analysis of convex functions. It is the goal of this volume to provide a synopsis of these topics, and thereby the theoretical back­ ground for the arithmetic of convex optimization to be treated in a sub­ sequent volume. The exposition of each chapter is essentially independent, and attempts to reflect a specific style of mathematical reasoning. The emphasis lies on linear and convex duality theory, as initiated by Gale, Kuhn and Tucker, Fenchel, and v. Neumann, because it represents the theoretical development whose impact on modern optimi­ zation techniques has been the most pronounced. Chapters 5 and 6 are devoted to two characteristic aspects of duality theory: conjugate functions or polarity on the one hand, and saddle points on the other. The Farkas lemma on linear inequalities and its generalizations, Motzkin's description of polyhedra, Minkowski's supporting plane theorem are indispensable elementary tools which are contained in chapters 1, 2 and 3, respectively. The treatment of extremal properties of polyhedra as well as of general convex sets is based on the far reaching work of Klee. Chapter 2 terminates with a description of Gale diagrams, a recently developed successful technique for exploring polyhedral structures.
