A list of interesting concepts, ideas that I stumbled upon at some point in time

**quadtree / spatial hashing**: two methods/data structures used to store objects while keeping their spatial relationship to some extent, allowing more effective calculations, e.g. for collision detection - both are described in this comparison (*2017-12-30*)**Delaunay triangulation**as dual to Voronoi tessellation: The Wikipedia article explains connection between these techniques (*2017-12-30*)**auxetic materials**are technically defined through a negative Poissonâ€™s ratio - meaning for example that they get thicker while stretched!- Generative Adversarial Networks (GAN)
- autoencoders
- context-free grammars
