Are you looking for new lectures for your course on algorithms, combinatorial optimization, or algorithmic game theory?  Maybe you need a convenient source of relevant, current topics for a graduate student or advanced undergraduate student seminar?  Or perhaps you just want an enjoyable look at some beautiful mathematical and algorithmic results, ideas, proofs, concepts, and techniques in discrete mathematics and theoretical computer science?  

Gems of Combinatorial Optimization and Graph Algorithms is a handpicked collection of up-to-date articles, carefully prepared by a select group of international experts, who have contributed some of their most mathematically or algorithmically elegant ideas.  Topics include longest tours and Steiner trees in geometric spaces, cartograms, resource buying games, congestion games, selfish routing, revenue equivalence and shortest paths, scheduling, linear structures in graphs, contraction hierarchies, budgeted matching problems, and motifs in networks.  

This volume is aimed at readers with some familiarity of combinatorial optimization, and appeals to researchers, graduate students, and advanced undergraduate students alike.

Hinter vielen Programmen stecken clevere Verfahren, die man als Algorithmen bezeichnet. Algorithmen lösen nicht nur mathematische Aufgaben, die sich mit Zahlen beschäftigen, sondern auch andere, ganz alltägliche Problemstellungen, bei denen logischer Spürsinn, räumliche Orientierung oder geschicktes Verhandeln gefragt sind, beispielsweise: Wie sollten Seeräuber eine Schatzkarte aufteilen, bzw. Bankangestellte den Geheimcode des Tresors? Wie ermittle ich den kürzesten Weg zwischen zwei Orten? Wie kann ich einen Kuchen gerecht aufteilen? Dieses Buch vollführt einen Streifzug durch die faszinierende Welt der Algorithmen. Es verlangt keine Vorkenntnisse, so dass Schüler ab der Mittelstufe und Informatik-interessierte Laien neue und überraschende Einblicke gewinnen können. In 43 Artikeln von Informatikern, die an Universitäten im In- und Ausland lehren, werden besonders elegante Algorithmen anschaulich und umgangssprachlich erklärt, so dass die besondere Faszination der Informatik spürbar wird.

Networks play a central role in today’s society, since many sectors employing information technology, such as communication, mobility, and transport - even social interactions and political activities - are based on and rely on networks. In these times of globalization and the current global financial crisis with its complex and nearly incomprehensible entanglements of various structures and its huge effect on seemingly unrelated institutions and organizations, the need to understand large networks, their complex structures, and the processes governing them is becoming more and more important.

This state-of-the-art survey reports on the progress made in selected areas of this important and growing field, thus helping to analyze existing large and complex networks and to design new and more efficient algorithms for solving various problems on these networks since many of them have become so large and complex that classical algorithms are not sufficient anymore. This volume emerged from a research program funded by the German Research Foundation (DFG) consisting of projects focusing on the design of new discrete algorithms for large and complex networks. The 18 papers included in the volume present the results of projects realized within the program and survey related work. They have been grouped into four parts: network algorithms, traffic networks, communication networks, and network analysis and simulation.
