GEFEST (Generative Evolution For Encoded STructures) is a toolbox for the generative design of physical objects.

In core it uses: 1. Numerical modelling to simulate the interaction between object and environment 2. Evolutionary optimization to produce new variants of geometrically-encoded structures

The basic abstractions in GEFEST are Point, Polygon, Structure and Domain. Architecture of the GEFEST can be described as:

The evolutionary workflow of the generative design is the following:

The dynamics of the optimisation can be visualized as (breakwaters optimisation case):

All details about first steps with GEFEST might be found in the quick start guide.

Tutorals for more spicific use cases can be found tutorial section of docs.

The latest stable release of GEFEST is on the main branch.

The repository includes the following directories:

• Package core contains the main classes and scripts. It is the core of GEFEST framework;
• Package cases includes several how-to-use-cases where you can start to discover how GEFEST works;
• All unit and integration tests can be observed in the test directory;
• The sources of the documentation are in the docs.
• Weights of pretrained DL models can be downloaded from this repository.

Note: To run the examples below, the old kernel gefest version, which can be installed on python 3.7 with:

pip install git+https://github.com/aimclub/GEFEST.git@4f9c34c449c0eb65d264476e5145f09b4839cd70

• Experiments with various real and synthetic cases
• Case devoted to the red blood cell traps design.

Migrated examples can be found in cases folder of the main branch.

Currently, we are working on integration of new types of physical objects with consideration of their internal structure.n

The major ongoing tasks:

• to integrate three dimensional physical objects
• to implement gradient based approaches for optimization of physical objects

Detailed information and description of GEFEST framework is available in the Read the Docs
