Evolutionary Solver Introduction

After the starting point of the Galapagos, there came another attempt to utilize this beautiful addition of David Rutten. This time, I worked over the night to tell it what I want. The aim was (or seemed to be) simple at first sight. I wanted several shapes (not one) to fit into an area, as smallest as possible, without overlaps. This is packing objects. A bounding box and area components quickly gave me the first fitness value. The area of the…

In large-scale projects, calculating tiling layouts for wall, floor, and ceiling surfaces becomes even more critical. Evolutionary optimization of these tilings seemed to be a viable approach yesterday. Considering how time-consuming and labor-intensive this process can be, I tried using Galapagos, an old but often overlooked feature in Grasshopper, which might be particularly useful in this situation. Galapagos provides an alternative interface for evolutionary optimization within Grasshopper. It works by minimizing or maximizing a fitness value you define, using parameters…

After several readings, I’ve understood the way of working the new and very interesting feature of Kangaroo 2: “Grab”. Now, we can actually grab the Grasshopper objects from Rhino viewport! Also, on one hand, the new Kangaroo has a very special way of working (not common to us, native Grasshopper users) and on the other hand, it is very very easy to use and understand now. I loved that. Here is the classical truss exercise I’ve made with my students…

I would like to share my Polyhedra library, which I have used in many projects. Initially, I wanted to build this code based on the geometric constructions of polyhedra. However, because I urgently needed it for projects I was working on at the time, I took a simpler route and hardcoded the vertex coordinates directly inside. Yes, that wasn’t quite in the spirit of designcoding, which is why I called it a “library” rather than a “Polyhedra Generator.” Currently, the…

Informal use of Voronoi diagrams can be traced back to Descartes in 1644 Peter Gustav Lejeune Dirichlet used two-dimensional and three-dimensional Voronoi diagrams in his study of quadratic forms in 1850. British physician John Snow used a Voronoi-like diagram in 1854 to illustrate how the majority of people who died in the Broad Street cholera outbreak lived closer to the infected Broad Street pump than to any other water pump. Voronoi diagrams are named after Georgy Feodosievych Voronoy who defined…
