“Solving a problem is the transformation of a given situation into a desired one. Evolutionary problem solvers are inspired from a model of natural evolutionary processes where organisms are ‘solutions’ to ‘problems’ set up by the environment.”

 Thomas Philip Runarsson



Design in contemporary architecture focuses on being evolutionary, temporal, changeable, but above all adaptable and customizable to the socio-technological contexts and to people’s needs. By working in tandem with new technologies through virtually endless approximations, designers can more easily and precisely ensure that every morphological decision responds to the multiple requirements of different environments.

In order to generate relevant answers, we are required to understand our context as well as the tools we have at our disposal. Only by understanding context and tools we can produce smart proposals, analyses, and studies. Familiarizing ourselves with the tools is the first important step. But in order to use them optimally, we must go deeper and understand their logic, test possibilities and discover their limitations and boundaries.

REACTION aims to investigate and experiment at the intersection of the physical and the digital world by merging digital fabrication technologies (3D Printing) and Computational Design techniques (Grasshopper & add-ons).
That’s why REACTION team propose two workshops 1401-1402 where those approaches will be deeply discussed and explained.

REACTION 1401 will introduce and focus on optimization processes while the second workshop, REACTION 1402, will start from digital optimizations logics to generate rapid prototyping for the creation of 3d printed physical models. Aim of both is to push designers towards new digital and tangible perspectives that reaches beyond the computer.

The main goal of REACTION 1401  focuses on understanding and controlling the logics of genetics or evolutionary algorithms.  Those evolutionary Solvers applies the principles of evolution found in nature to the problem of finding an optimal solution to a Solver problem.  We will explore the potentials of those design techniques. Environmental and energetic data will be the main inputs of those processes that will drive our design choices towards flexible, progressive, interactive solutions.



The workshop is open to all participants, no previous knowledge of Rhinoceros, Grasshopper or tailoring techniques is required (although an introductory knowledge is welcome). Participants should bring their own laptop with a pre-installed software.  The software package needed has no additional cost for the participant (Rhino can be downloaded as evaluation version, Grasshopper and plugins are free). These softwares are subject to frequent updates, so a download link to the version used in the workshop will be sent to the participants a few days before the workshop.
