Métro berlinois – Optimisation de la grille des horaires

La grille d’horaires de 2005 pour ce réseau a été calculée par Matheon à l’institut de Mathématiques de Berlin. La clef de ce travail était de l’ordre de l’état de l’art des techniques d’optimisation combinatoire. Les transports publics de Berlin sont modélisés comme un graphe où les stations sont des nœuds reliés par des arêtes et soumis à certaines contraintes. La solution optimale pour son fonctionnement (minimisant le temps d’attente aux stations et le nombre de trains nécessaires) est cachée quelque part dans l’ensemble de toutes les solutions possibles respectant les contraintes données. Mais cet ensemble est beaucoup trop grand pour être exploré dans son ensemble, même par les plus puissants des calculateurs. Des méthodes mathématiques astucieuses produisent des algorithmes puissants permettant d’éliminer de larges pans de cet ensemble pour concentrer la recherche dans les sous-régions plus restreintes où se trouvent l’optimum.

IMAGINARY at Bar-Ilan University

This exhibition is part of a project funded by the German Ministry of Education and Research under the brandname Research in Germany. This is the second of two IMAGINARY exhibitions in Israel in 2015/2016. The first exhibition was at the Clore Garden of Science at the Weizmann Institute in Rehovot until mid of December. 

The exhibition is open Sunday to Friday, from Thursday the 24th of December until Friday the 29th of January. During that period the exhibition is closed on two days - on Sunday Dec 27 and on Thursday Dec 31  (due to other events in the center).

The entrance is free of charge.

There is a cafeteria inside the venue so that visitors have the opportunity to sit down and  buy refreshments.

Big groups have to coordinate with Arkadius Kalka.

The exhibition is accompanied by a SURFER competition for Israel which continues until 12 April 2016:

Go to the event site or directly to the competition site.

IMAGINARY goes North and East - upcoming exhibitions in Denmark, Russia and Norway

This Friday, April 5, a special IMAGINARY exhibition featuring sculptures and images will be shown for the first time in Denmark, at the Steno Science Museum in Aarhus, see here for the event info. It will be open until August 31, 2013. Then the exhibition series in Russia will find its continuation in a one week exhibition at Pushchino, a small town south of Moscow. It is the fifth exhibition in Russia, coordinated in collaboration with the German Embassy in Moscow (and some more are in the planning pipeline). In May IMAGINARY will be honoured to travel to Norway - also a first-timer - to be shown after the celebrations of the Abel prize ceremony in Oslo. It will be presented in a science museum in Trondheim - more detailscon be found here.

And if you are in Spain (and up for the Camino de Santiago), don’t forget to stop by the University Church next to Santiago de Compostela’s cathedral to see the ongoing RSME-IMAGINARY there - open until May 16, 2013.

IMAGINARY Israel announced

On the occasion of the 50 year long diplomatic relations between Germany and Israel, the project IMAGINARY Israel by the Mathematisches Forschungsinstitut Oberwolfach (MFO) will be announced in conjuction with a visit by German Federal Minister of Education and Research Johanna Wanka at the Weizmann Institute of Science on Feburary 10. The project consists of two mathematics exhibitions for the general public and two workshops mainly for young mathematicians from Germany and Israel.

Within this project, IMAGINARY is given the opportunity to collaborate with an excellent science communication center (the Clore Garden of Science The Davidson Institute of Science Education, the Weizmann Institute of Science) in order to share experiences in staging inspiring exhibitions and communicating current mathematics research to the general public. The collaboration will lead to the first ever IMAGINARY exhibition being shown in Israel during the summer of 2015 at the Clore Garden of Science in Rehovot , followed by a second exhibition shown in Tel Aviv towards the end of 2015 and the beginning of 2016. 

Watch out for the exact date announcements of the two planned exhibitions!

We are pleased to announce that IMAGINARY Israel has received funding from the Federal Ministry of Education and Research (BMBF) and is organized within the “Research in Germany” campaign of the BMBF, with the aim of strengthening the traditionally very good mathematical research collaborations between the two countries.

The software is designed to illustrate maritime seismic imaging and includes

  • a graphic tool to play around with wave reflections
  • a simulation environment demonstrating wave propagation
  • an interactive selection of sources and receivers for seismic imaging
  • several explanations of the basic ideas
  • some information on mathematics and numerics
  • many additional features to discover

For more details and a demonstration video see our website at http://www. waves. kit.edu/pyfwi.php

Description

Description: 

À chaque tour du jeu, vous verrez des polytopes dans la partie supérieure de l’écran.

Vous pouvez les tourner pour les regarder sous toutes les faces.

Dans la partie inférieure de l’écran, vous voyez autant de patrons plans qu’il y a de polytopes en haut.
Ces patrons sont obtenus par déroulement des polytopes sur un plan.
L’objectif est de faire correspondre chaque polytope avec son patron.
Vous pouvez permuter tout couple de patrons en les déplaçant l’un sur l’autre/

MatchTheNet est disponible en français, en anglais et en allemand. Sept niveaux de difficultés sont proposés pour un nombre de polytopes allant de 2 à 5. Le programme est bien adapté à des expositions temporaires et permanentes et aux musées scientifiques.

MatchTheNet est basé sur polymake, un logiciel libre pour la recherche en géométrie des polyèdres. Il permet de travailler avec des polytopes, des polyèdres tout autant qu’avec des complexes simpliciaux, des matroïdes, des cycles tropicaux et plus encore.
