Historical and recent developments at international ?nancial markets show that it is easy to loose money, while it is dif?cult to predict future developments and op- mize decision-making towards maximizing returns and minimizing risk. One of the reasons of our inability to make reliable predictions and to make optimal decisions is the growing complexity of the global economy. This is especially true for the f- eign exchange market (FX market) which is considered as one of the largest and most liquid ?nancial markets. Its grade of ef?ciencyand its complexityis one of the starting points of this volume. From the high complexity of the FX market, Christian Ullrich deduces the - cessity to use tools from machine learning and arti?cial intelligence, e.g., support vector machines, and to combine such methods with sophisticated ?nancial mod- ing techniques. The suitability of this combination of ideas is demonstrated by an empirical study and by simulation. I am pleased to introduce this book to its - dience, hoping that it will provide the reader with interesting ideas to support the understanding of FX markets and to help to improve risk management in dif?cult times. Moreover, I hope that its publication will stimulate further research to contribute to the solution of the many open questions in this area.

The programming language PASCAL-XSC (PASCAL eXtension for Scientific Computation) significantly simplifies programming in the area of scientific and technical computing. PASCAL-XSC provides a large number of predefined data types with arithmetic operators and predefined functions of highestaccuracy for real and complex numbers, for real and complex intervals, and for the corresponding vectors and matrices. Thus PASCAL-XSC makes the computer more powerful concerning the arithmetic. Through an implementation in C, compilers for PASCAL-XSC are available for a large variety of computers such as personal computers, workstations, mainframes, and supercomputers. PASCAL-XSC provides a module concept, an operator concept, functions and operators with general result type, overloading of functions, procedures, and operators, dynamic arrays, access to subarrays, rounding control by the user, and accurate evaluation of expressions. The language is particularly suited for the development of numerical algorithms that deliver highly accurate and automatically verified results. A number of problem-solving routines with automatic resultverification have already been implemented. PASCAL-XSC contains Standard PASCAL. It is immediately usable by PASCAL programmers. PASCAL-XSC is easy to learn and ideal for programming education. The book can be used as a textbook for lectures on computer programming. It contains a major chapter with sample programs, exercises, and solutions. A complete set of syntax diagrams, detailed tables, and indices complete the book.

The ESPRIT Project 1072, DIAMOND (Development and Integration of Accurate Mathematical Operations in Numerical Data-Processing) was carried out from January 1986 through April 1989 by the five partners Siemens Miinchen (prime contractor), CWI Amsterdam, University of Karlsruhe (Institut fiir Ange wandte Mathematik), NAG Oxford and University of Bath (subcontractor to NAG). The technical work was divided into three main work packages with one additional work package for miscellaneous topics. The major goals of this project, according to its title, were to develop a set of accurate numerical algorithms (work package 3) and to provide tools to support their implementation by means of an embedding of accurate arithmetic into programming languages (work package 1) and by transform ation techniques which either improve the accuracy of expression evaluation or detect and eliminate presumable deficiencies in accuracy in existing programs (work package 2). A great variety of working papers describing and discussing the results of these work packages have been written during the collaboration of the project. This book (Accurate Numericlll A 19oritltms) mainly summarizes the results of work package 3, carried through by the two partners Karlsruhe University and NAG Oxford under the leadership of the editors and Dr. G. S. Hodgson. Another book (Improving Floating-Point Programming, J. Tliley, to appear 1989), edited by P.J.L. Wallis, which is one of the DIAMOND project's final deliverables, concentrates more on the fundamental tools.

Christian Ullrich entwickelt ein Modell, das das Zusammenspiel zwischen Konkurrenz und Kooperation beschreibt und mit dem die Folgen eigener und fremder Entscheidungen systematisch abgeschatzt werden konnen. Die Dynamisierung dieses Modells ermoglicht es schliesslich, wesentliche Massnahmen zur Organisation dauerhafter Kooperation abzuleiten."

PASCAL-XSC (PASCAL-e"X"tension for "S"cientific "C"omputation) ist eine Erweiterung der weitverbreiteten Programmiersprache PASCAL. Sie verfolgt das Ziel, das Programmieren, insbesondere im Bereich technisch-wissenschaftlicher Anwendungen, durch zusAtzliche Sprachkonzepte wie Module, dynamische Felder und Operatoren erheblich zu vereinfachen. Eine optimale Arithmetik mit hochgenauen Standardfunktionen und exakter Ausdrucksauswertung ermAglicht eine automatisierte, zuverlAssige Kontrolle der berechneten Ergebnisse. Damit unterstA1/4tzt PASCAL-XSC die Entwicklung von Routinen mit automatischer Ergebnisverifikation. Mittels der Compiler-Implementierung in C kann PASCAL-XSC auf PC's, Workstations, GroArechnern und Supercomputern gleichermaAen eingesetzt werden. In dem vorliegenden Lehr- und Handbuch wird PASCAL-XSC vollstAndig beschrieben. Zur praktischen Verwendung und zum leichteren Kennenlernen und Vertrautwerden mit den A1/4ber PASCAL hinausgehenden neuen Sprachelementen ist ein ausfA1/4hrlicher Abschnitt mit Aoebungsaufgaben und LAsungen aufgenommen worden. Ein kompletter Satz von Syntaxdiagrammen, sowie ausfA1/4hrliche Register und Verzeichnisse schlieAen dieses Buch ab.
