Innovation, Industry dynamics, Bounded rationality, Learning, Genetic algorithms Research and development (R&D) decisions are characterized by a strong uncertainty concerning the return on investment. As a matter of fact, fixed rules are not a necessary characteristic of decisions under bounded rationality: the main characteristic is procedural rationality ([ Simon, 1976 ]). Of course, one could choose to implement a simple process of trial and error but such a process would contain a strong ad hoc element in the way it models the sequence of trials 2 .

How many hours have you used the Internet today or in an average week? Do you even remember the first time you surfed the Interweb? It wasn’t that long ago when some of us didn’t even know what the Internet was.
Now you can’t do much of anything today without touching it. And yet, if you stopped to ask people what does the Internet physically look like, most would be perplexed by the very thought. Launch Interactive Map of the Internet (zoom in and out) Methodology Non-Geek Version – The Map of the Internet is a visual representation of all the networks around the world that are interconnected to form the Internet as we know it today.

They have several ways of crawling, can swim, and even glide through the air.
And all that with an extremely simple geometry. Snakes are a precious source of inspiration for the robotician, enabling one to imagine a robot capable of movement in chaotic environments such as post-catastrophic ruins. Swim like a fish Fish enjoy unrivalled manoeuvrability and efficiency, inspiring roboticians and hydrodynamicists to conceive innovative underwater robots. See like a fly The extraordinary performance of supposedly simple animals are a source of wonder for engineers.
Fly like an insect Insects, like hummingbirds, are capable of extremely rapid and precise aerial manoeuvres. Sensory-motor integration The nervous system integrates the information necessary to link perception to action and the perception of action.

I - D'abord un peu de théorie (c'est le cas de le dire)... (Les astérisques dans le texte renvoient aux définitions dans le glossaire (lien) situé dans un autre article : indispensable pour bien comprendre le sens de certains termes). Ce premier article jette les bases de la théorie des jeux appliquée à l'évolution biologique, en préambule à plusieurs articles traitant de cas pratiques (à venir) au niveau des plantes succulentes. Bien qu'il s'agisse d'une théorie mathématique, le formalisme mathématique de cet article est minimal pour des raisons de lisibilité. L'article reste cependant très théorique : les cas concrets seront abordés dans les exemples à venir. II - La théorie des jeux classique La théorie des jeux est une théorie des sciences sociales, politiques et économiques qui étudie les interactions entre des protagonistes, généralement dans des situations d'antagonisme*, à travers des modèles appelés jeux*.
Comme domaines divers d'application de la théorie des jeux on peut citer : Blue Brain Project. In Search for Intelligence, a Silicon Brain Twitches. Économie de la connaissance.
