Game theory and the Cuban missile crisis January 2001 Theory of Moves "We're eyeball to eyeball, and I think the other fellow just blinked" were the eerie words of Secretary of State Dean Rusk at the height of the Cuban missile crisis in October 1962. He was referring to signals by the Soviet Union that it desired to defuse the most dangerous nuclear confrontation ever to occur between the superpowers, which many analysts have interpreted as a classic instance of nuclear "Chicken". Chicken is the usual game used to model conflicts in which the players are on a collision course. While ostensibly a game of Chicken, the Cuban missile crisis is in fact not well modelled by this game. On the other hand, the "theory of moves," which is founded on game theory but radically changes its standard rules of play, does retrodict, or make past predictions of, the leaders' choices. Classical Game Theory and the Missile Crisis Game theory is a branch of mathematics concerned with decision-making in social interactions. Backward Induction

Issuu - You Publish Poll: Which methods/algorithms did you use for data analysis in 2011? Regional breakdown is US/Canada, 40.2% Europe, 37.6% Asia, 10.3% Latin America, 5.8% Africa/Middle East, 3.2% Australia/NZ 2.9% We grouped Industry/Gov in one group and Academic researchers/Students into a second group, and computed the "affinity" of the algorithm to Industry/Gov as N(Alg,Ind_Gov) / N(Alg,Aca_Stu) ---------------------------------- N(Ind_Gov) / N(Aca_Stu) Thus algorithm with affinity 1.5 is used 50% more in Industry/Government than by Academic Researchers or students, and the algorithm with affinity 0.6 is used only 60% as much in Industry. The most "industrial" algorithms ( with the highest Industry / Gov "affinity") are: Uplift modeling, INF (no academic users) Survival Analysis, 2.47 Regression, 2.00 The most "academic" algorithms ( with the lowest Industry / Gov "affinity") are: Genetic algorithms, 0.60 Support Vector (SVM), 0.66 Association Rules, 0.83 The following table shows the algorithms ranked by Industry affinity (third column).

Mobile Code Portability the Focus of Adobe 2011 Release Train We Recommend These Resources Adobe has its ear to the ground when it comes to it's core user base of developers and designers. They know that figuring out how to develop and design applications for smartphones (and now tablets as well) can involve a steep learning curve. They also realize that web developers want to use the open source technologies they trust, like HTML5, CSS3, and jQuery. Adobe even has a special treat for the fervent contingent of server-side ColdFusion developers. Today Adobe is introducing its new developer tools and creative suite to keep up with a rapidly growing software and web development industry with constantly changing needs. Flex 4.5 and Flash Builder 4.5ColdFusion Builder 2.0Creative Suite 5.5Here is some info about each release: Flash Builder 4.5 and Flex 4.5 Today developers will see an overhaul of Adobe's mobile development features in the new Flex and FlashBuilder. Flex 4.5 focuses on three main areas for its new features: ColdFusion Builder 2.0

Compte rendu : « L’impression à la demande : une révolution pour l’objet-livre ? » Luc Spooren - Photo par Élodie Picard Du 7 au 11 septembre 2009, le Centre pour l’édition électronique ouverte a organisé son Université d’été de l’édition électronique ouverte. Nous mettons à votre disposition les comptes rendus des conférences et des cours donnés durant cette semaine de formation. Ce compte-rendu a été rédigé par Pierre André, chargé d’édition au Cléo. Intervenants : Luc Spooren et Virginie Clayssen Jeudi 10 septembre 2009 – 18h-19h (amphi Charve – Université St Charles) Luc Spooren est directeur de la société Unibook. L’impression numérique, l’impression à la demande Il convient de distinguer l’impression numérique (le processus technique, s’apparentant à un copieur élargi), et l’impression à la demande (service proposé aux particuliers ou aux éditeurs, dit aussi print on demand, parfois abrégé POD). Il existe deux croyances tenaces sur l’impression numérique. Lorsqu’il est question d’impression à la demande, il faut se demander : à la demande de qui ? Nouveaux modèles

Eurozone debt web: Who owes what to whom? The circle below shows the gross external, or foreign, debt of some of the main players in the eurozone as well as other big world economies. The arrows show how much money is owed by each country to banks in other nations. The arrows point from the debtor to the creditor and are proportional to the money owed as of the end of June 2011. The colours attributed to countries are a rough guide to how much trouble each economy is in. Click on a country name to see who they owe Europe is struggling to find a way out of the eurozone crisis amid mounting debts, stalling growth and widespread market jitters. But, with global financial systems so interconnected, this is not just a eurozone problem and the repercussions extend beyond its borders. While lending between nations presents little problem during boom years, when a country can no longer handle its debts, those overseas banks and financial institutions that lent it money are exposed to losses. GDP: €1.8 tn Foreign debt: €4.2 tn

Python from Scratch: Getting Started Welcome to Python from Scratch, where I'm going to teach you the ins and outs of Python development... from scratch. In this first lesson, we're going to choose a version, install Python, and then create the obligatory "Hello world" script. If you're already familiar with Python, feel free to skip ahead to a later lesson in the series. Video Tutorial Companion Article Choosing a Version "It's important to choose the right version." There are two versions of Python that are currently being developed: 2.x and 3.x. To make things easier, a lot of features that are being added to version three have also being added to version two, so there's less need to worry about the differences. Installing the Interpreter Once you've chosen a version, it's time to install. Python Shell- lets you run commands line by line.IDLE GUI - lets you write more complex scripts, and run them in one go.Text Editor - any text editor that runs on you system. For now, launch the shell to test if it works correctly.
