The solution of complex problems arising in current applicative areas (such as economics, fluid dynamics simulations or handling of Web information) requires great computational efforts. The development of new high performances architectures must be combined with the design of efficient algorithms. This research group investigates models and algorithms in the following applicative areas: algorithmics for web technologies; computational economics; algorithmics for wireless networks and smart mobility; computational biology. This applied research has been joined by basic research in the field of numerical linear algebra with particular interest in the solution of large linear systems (with and without structure) and in the study of regularization techniques for ill posed linear inverse problems. Recently we started a scientific dissemination activity in the fields of game theory, logic, cryptography and mathematical economics.
