Primordial Particle System

An implementation of the Primordial Particle System (PPS) described in:

Schmickl, T., Stefanec, M. & Crailsheim, K. How a life-like system emerges from a simplistic particle motion law. Sci Rep 6, 37969 (2016). https://doi.org/10.1038/srep37969

Explanation video by the authors of the article (not this implementation):

How life emerges from a simple particle motion law: Introducing the Primordial Particle System

Installation

$ go install github.com/fzipp/pps/cmd/pps-simulate@latest

Usage

$ pps-simulate
Visit http://localhost:8080 in a web browser

It uses the following parameter set (as described in the article) by default:

PPS =〈r=5, α=180°, β=17°, v=0.67〉

The parameters, the particle density (DPE) and the size of the universe can be modified via command line flags:

$ pps-simulate -r=4 -alpha=180 -beta=17 -v=0.67 -dpe=0.08 -size=150x150

The port is configurable as well:

$ pps-simulate -http=:6060

Get help about the flags:

$ pps-simulate -help
