Annotation The Symposium on Theoretical Aspects of Computer Science is organized jointly by the Special Interest Group for Applied Mathematics of AFCET (Association FranAaise de CybernA(c)tique Economique et Technique) and the Special Interest Group for Theoretical Computer Sciences of GI (Gesellschaft fA1/4r Informatik). It is held alternately in France and in Germany. This volume contains two invited papers, on combinatorial methods in computer science, and on the complexity of local optimization, and 24 contributions on theoretical aspects of computer science. Some software systems are presented showing the possibilities of applying theoretical research to the realization of software tools.
Algorithms specify the way computers process information and how they execute tasks. Many recent technological innovations and achievements rely on algorithmic ideas – they facilitate new applications in science, medicine, production, logistics, traffic, communi¬cation and entertainment. Efficient algorithms not only enable your personal computer to execute the newest generation of games with features unimaginable only a few years ago, they are also key to several recent scientific breakthroughs – for example, the sequencing of the human genome would not have been possible without the invention of new algorithmic ideas that speed up computations by several orders of magnitude. The great...
