They shift the emphasis from ‘form making’ to ‘form finding’
Various generative form-finding techniques existed in architecture long before the digital revolution. At the start of the twentieth century, many visionary architects, engineers, and designers, such as Frederick Kiesler and Frei Otto, were applying design methods that were very similar to today’s computational approach. It seems that today’s new computational design techniques are not as new as they seem, nor impossible to practise without the use of computational tools. These techniques are oft en described by terms such as ‘generative design’, ‘parametric design’ or ‘algorithmic design’, to name but a few.
The shape generation process is comprised of several steps:
i. A building plot is extruded to reflect the built volume it is predicted to contain (see Predictive Analytics).
ii. The volume is populated randomly with points and spin forces at various angles.
iii. The points revolve around the force fields, on a loop, drifting in and out of their gravitational field.
iv. On each round, the most distant points in the point cloud are determined (using convex hull), and used to measure the volume of
the point cloud.
v. The loop ends once the volume of the point cloud is equal to the predicted built volume in that particular plot. This gives us the
the volumetric shape of the building.

By changing just a few variables this procedure can produce thousands of different Iterations.
The question then become that of selecting the best sulutions.

The more complax We need to differentiate between Linear Equations and Non-Linear Equations. that cities and regions are ‘self-organizing’ systems, where the interplay of system feedbacks and historical events shape the evolutionary process, and both the overall performance and the multiple local experiences that emerge.

Let's consider two geometries of different sizes, the bigger the surface area ratio compared to its volume, the easier to generate air supply and electricity
Linear testing
The surviving single-object iterations were then tested as multi-object configurations. In order to prioritize a reach built environment, we set the fitness criteria to be the typological difference between forms in each combination (calculated as the distance of dimensions of a containing polygon) .
Non-Linear testing
Now it was time to test out top 5 linear equation. The attraction of both cellular automata and agent based models is they represent some of the simplest frameworks possible for demonstrating complex systems behavior. L
