Projektbeschreibung
Die Lücke zwischen Theorie und Praxis in der numerischen Optimierung schließen
Numerische Optimierung ist in vielen Bereichen, von der Wissenschaft bis zur Industrie, enorm wichtig. Durch die zunehmende Komplexität moderner Probleme ist es in der Theorie jedoch schwer, mit den praktischen Anforderungen Schritt zu halten. Infolgedessen wird die Lücke zwischen theoretischen Algorithmen und ihren realen Anwendungen immer größer. Daraus ergeben sich häufig widersprüchliche Ratschläge aus Theorie und Praxis. Ziel des ERC-finanzierten Projekts CASPER ist es, diese Lücke zu schließen, indem die theoretischen Grundlagen von Optimierungsalgorithmen verbessert werden. Dazu werden Methoden und Instrumente zur effektiven Analyse von Algorithmen entwickelt. Diese Instrumente werden zur Entwicklung von Algorithmen beitragen, die bei großen Problemen und in modernen Computerumgebungen funktionieren. Außerdem werden quelloffene Instrumente und validierte Algorithmen für den Einsatz in Bereichen wie maschinelles Lernen und Robotik entwickelt.
Ziel
Numerical optimization is a fundamental tool with a growing impact in many disciplines from science to industry. Many of its successes are due to theoretical advances, which are key to developing trust in numerical algorithms. While trust is non-negotiable in many applications, the complexity level of modern and future problems makes it very hard for theory to keep up with efficient proposals. Arguably worse, while both theory and experimental practice are key to the field, their respective recommendations often conflict with each other and the gap between theory and practice gets embarrassingly large.
The main objective of this proposal is to push forward the theoretical foundations of algorithmic optimization to drastically reduce the gap between fundamental theoretical understanding and practical scenarios. To achieve this, we will develop principled and systematic approaches to algorithmic analyses, as well as computer-aided performance certification tools. Whereas my recent works show that such techniques already allow going far beyond the surprisingly few classical templates for algorithmic analysis, they have currently very limited applicability beyond simple scenarios. We will largely broaden the techniques to develop and study modern algorithms with working guarantees that can (i) scale to unprecedented problem and data sizes, (ii) adapt to common problem structures, and (iii) be deployed on modern massively parallel computing environments. On the way, this project will allow for simplified certification and validation of existing theory, an absolute necessity in this era of massive scientific production.
Outcomes of CASPER will include symbolical and numerical algorithmic certification and development tools, as well as algorithms with unprecedented working guarantees. The tools will be released as open-source libraries and algorithms validated on key benchmarks that include challenging machine learning and robotic tasks.
