According to Brian Skyrms1, Democritus was one of the first philosophers to hold that signals are conventional and arose by chance. Lewis-Skyrms signaling games give us a framework to explore the consequences of that idea in more detail. The tools in this project were developed to support that task, namely by making it easier to set up different games, run simulations, and analyse the results.
