Kombinatorische Herausforderungen der Algorithmischen Biologie 
Seminar im WS 2001/2

Welche algorithmischen Probleme wirft die Sequenzierung des menschlichen Genoms auf und wie wurden sie bislang gelöst? In diesem Beispiel wie auch bei vielen anderen aktuellen Forschungsgebieten der algorithmischen Biologie treten kombinatorisch komplexe, oftmals NP-harte Probleme auf. In der praktischen Lösung dieser Probleme ist deshalb der Einsatz von heuristischen Verfahren, Näherungslösungen oder exakten, problemspezifische Eigenschaften ausnutzenden Algorithmen nötig. (Insbesondere letzterer Ansatz steht in engem Zusammenhang mit von der Deutschen Forschungsgemeinschaft (DFG) geförderten Projekten der Veranstalter.)

Dieses Seminar richtet sich nicht nur an Bioinformatik-Studierende, sondern auch an Studierende der Informatik und Mathematik mit Interesse an algorithmischen, durch die Biologie motivierten Fragestellungen.
