Il libro narra la vicenda di Rut, quindicenne, da poco trasferitasi con la famiglia in Germania al seguito del padre che lavora per un'azienda produttrice di Software. Nella nuova scuola Rut sta attraversando un periodo di crisi quando il padre, un giorno, le regala un computer nuovo. E' l'inizio di un'avventura. Nel computer e infatti installato Vim: un programma che ascolta, capisce e risponde alle domande di Rut, la quale finisce per confidargli le proprie difficolta a scuola, soprattutto nei confronti della matematica. Raccontata da Vim, quella che sembrava una disciplina astratta e...

Recently much attention has been devoted to the optimization of transportation networks in a given geographic area. One assumes the distributions of population and of services/workplaces (i.e. the network's sources and sinks) are known, as well as the costs of movement with/without the network, and the cost of constructing/maintaining it. Both the long-term optimization and the short-term, "who goes where," optimization are considered. These models can also be adapted for the optimization of other types of networks, such as telecommunications, pipeline or drainage networks. In the...

Mit dem Auto auf moglichst kurzem Wege von Munchen nach Hamburg zu fahren, ist keine grosse Ubung: Es geht auf die Autobahn und dann immer geradeaus. Eine Route durch 15 112 Orte in Deutschland zu planen, ohne ein Dorf, eine Stadt zwei Mal zu besuchen, ist dagegen deutlich schwieriger.

Ruth, 15 Jahre und von Mathematik alles andere als begeistert erschliesst mit ihrem neuen Computer die Welt der Routenplanung und der dazugehorigen Mathematik, ohne die ein "Handlungsreisender" niemals die oben gestellte Aufgabe losen konnte.

"Dies ist eine wundervoll lockere Einfuhrung in ein...

Le but de ce livre est de donner une introduction aux methodes de Monte-Carlo orientee vers la resolution des equations aux derivees partielles. Apres des rappels sur les techniques de simulation, de reduction de variance et de suites a discrepance faible, les auteurs traitent en detail le cas des equations de transport, de l'equation de Boltzmann et des equations paraboliques de diffusion. Dans chaque cas ils introduisent les processus aleatoires associees et discutent les techniques d'implementation.

Leading researchers in the field of Optimal Transportation, with different views and perspectives, contribute to this Summer School volume: Monge-Ampere and Monge-Kantorovich theory, shape optimization and mass transportation are linked, among others, to applications in fluid mechanics granular material physics and statistical mechanics, emphasizing the attractiveness of the subject from both a theoretical and applied point of view.

The volume is designed to become a guide to researchers willing to enter into this challenging and useful theory.

To this reviewer s knowledge, this is the first book accessible to the upper division undergraduate or beginning graduate student that surveys linear programming from the Simplex Method via the Ellipsoid algorithm to Karmarkar s algorithm. Moreover, its point of view is algorithmic and thus it provides both a history and a case history of work in complexity theory. The presentation is admirable; Karloff's style is informal (even humorous at times) without sacrificing anything necessary for understanding. Diagrams (including horizontal brackets that group terms) aid in providing...
