How it works



  • Hosts (any life form) have characteristics. When hosts reproduce sexually or asexually, the offspring characteristics are its parent’s plus mutations.
  • Hosts behaviour code MUST be generic, so we can either implement simple heuristics like state-machines, behaviour trees or go more complex like reinforcement learning.
  • Observers can trigger artificial selection, the goal is to implement actions that offer the possibility to influence evolution. Currently what came to my mind: any way to protect, harm, heal, feed … some species


git clone



  1. Docker
  2. Install kubectl

# Should run Unity unit tests (but unfortunately Unity CLI rarely works on Ubuntu 20.04 at least so it Seg Fault)
# Run integration tests with Helm (imply that you have a configured k8s/k3s cluster, Helm)
make test
