Avviso di seminari > 24/01/08 > > ore 15-16 Prof. Dr. Gert Wanka, Chemnitz University of > Technology, Chemnitz, Germany: "Closedness Type and > Subdifferential Regularity Conditions for Conjugate Duality in > Infinite Dimensional Spaces". > > ore 16-16.30 coffee break > > ore 16.30-17.30 Prof. Dr. Radu Ioan Bot, Chemnitz University of > Technology, Chemnitz, Germany: "On an open problem regarding > totally Fenchel unstable functions". > > Approfitto dell'occasione per chiederle anche di diffondere > notizia di altri due seminari che si terranno presso il > Dipartimento di Matematica Applicata "U.Dini" il 30/01/08. > > > 30/01/08 > > ore 10-11 Prof. Immanuel M. Bomze, University of Vienna: " On the > road to tractability: from combinatorial optimization via > copositive programming to SDP-based approximation". > > Abstract: > > Quite many combinatorial and some important non-convex continuous > optimization problems admit a copositive representation, where the > complexity of solving non-convex programs is shifted towards the > complexity of sheer feasibility. > > Using characterizations of copositivity, one arrives at various > SDP-based approximations. However, not all of these are tractable > with current technology. This talk addresses some approaches on > which tractable semidefinite-programming (SDP) approximations may > be based, along with specific strategies to generate interesting > test instances of intermediate complexity. > > ore 11-11.30 coffee break > > ore 11.30-12.30 Prof. Fabio Schoen, Università di Firenze: > "Practical Global Optimization: from the Circle Packing Contest to > Binary Atomic Clusters and beyond". > > Abstract: > > In this talk we will review some recent computational results in > large scale global optimization. Starting from the techniques we > used and which led our group to win the Circle Packing Contest > (http://www.recmath.org/contest/CirclePacking) we will explain how > that experience proved itself extremely useful in a quite > different context, that of finding the global minimum energy > configuration of atomic clusters composed by atoms of two > different types. Differently from classical (e.g. Lennard-Jones or > Morse) potential energy optimization, for the optimization of > binary clusters the combinatorial nature of the problem has to be > taken into account. In fact, once the coordinates of N atoms have > been decided, through the minimization of a smooth function, > exponentially many isomers can be defined, by assigning different > atom types to different locations (some sort of a 3-dimensional > anagram). We will present our quite simple strategy which led us > to find improved configuration for at least 90 of the previously > known putative optima deposited at the Cambridge Cluster Database. > Very recently we tried to apply a similar algorithmic framework to > another, quite unrelated, contest: finding the best departure and > travel times of a spacecraft which, starting from Earth, should > visit some (3) asteroids to be chosen in a known group. The > objective was to minimize a function of fuel consumption and of > the stay time at each asteroid, with constraints on the maximum > length of the mission (less than 10 years). Although quite > unexperienced in this field and although the competition ran for > only one month, we ranked 10-th out of 23 participants: in the > talk we will briefly sketch our approach. > > > Nel ringraziarla le porgo distinti saluti, > Barbara Panicucci. > > -- > Open WebMail Project (http://openwebmail.org) > > _______________________________________________ Settimanale mailing list Settimanale(a)mail.dm.unipi.it https://mail.dm.unipi.it/mailman/listinfo/settimanale
