Sommario/riassunto |

When trying to find new methods and problem-solving strategies for their research, scientists often turn to nature for inspiration. An excellent example of this is the application of Darwin's Theory of Evolution, particularly the notion of the 'survival of the fittest', in computer programs designed to search for optimal solutions to many kinds of problems. These 'evolutionary algorithms' start from a population of possible solutions to a given problem and, by applying evolutionary principles, evolve successive generations with improved characteristics until an optimal, or near-optimal, soluti |

Sommario/riassunto |

The current diffusion of a design mentality that proceeds by the assignment of themes, in the design of both sites and individual architectural elements, makes it useful to ponder the subject of the theme park that is the purest example of this. More specifically, what this signifies is questioning ourselves about the relations between the natural element, the architecture and the symbol. Addressing the argument with the eye of the landscape architect, it appears dense with repercussions, focusing the question of what landscape we are dealing with and what its design entails. This is an issue of landscape architecture in the purest sense and in its most extreme forms. |
