Enjoyed visiting @uni-graz.at for the Complexity of Life Conference last week. Amazing talks (e.g. @hirokisayama.bsky.social, @douglasguilbeault.bsky.social plus @suetl.bsky.social from my team), and perspectives! Thanks to Daniel Reisinger & co for organising! colibri.uni-graz.at/de/complexit...

Decentralized self-organization — a basic principle of complex adaptive systems. We know this simple principle is sufficient to explain such systems since it has been done in computer simulation since about 1986. Here is a video from a modern approach to that old model:
