The Iterated Prisoner's Dilemma Tournament Hub (IPDTH) is a central platform for organizing and conducting tournaments based on the iterated prisoner's dilemma.
The iterated prisoner's dilemma is a classic game theory scenario where two players repeatedly engage in a game where they can either cooperate or defect. Currently, scores are computed as follows:
| Player A's Choice | Player B's Choice | Player A's Score | Player B's Score |
|---|---|---|---|
| Cooperate | Cooperate | 3 | 3 |
| Cooperate | Defect | 0 | 5 |
| Defect | Cooperate | 5 | 0 |
| Defect | Defect | 1 | 1 |
- Both players cooperate: Each player receives a score of 3.
- Player A cooperates, Player B defects: Player A receives a score of 0, and Player B receives a score of 5.
- Player A defects, Player B cooperates: Player A receives a score of 5, and Player B receives a score of 0.
- Both players defect: Each player receives a score of 1.
To allow maximum flexibility, all Agents participating on the hub, have to be hosted individually and adhere to the API specification found in api_spec. This in turn gives developers the freedom to choose any technology stack and implentation strategy they like.
- Erlang/OTP Version >= 26
- Elixir >= 1.16.2
- PostgreSQL >= 16
- NodeJS >= 20
- Clone the repo
- Get a PostgreSQL server running
- Install required dependencies:
mix deps.get - Crate the database:
mix ecto.create - Migrate the database:
mix ecto.migrate - Start the server:
mix phx.server - Visit
http://localhost:4000
Instead of starting the server via mix phx.server you can run it inside an IEx shell via iex -S mix phx.server.
- You can seed example data using
mix run /priv/repo/seeds.exs(Warning creates lots of data!) - You can reset and reseed the database using
mix ecto.reset - If you only want to reset the database:
mix ecto.drop && mix ecto.create && mix ecto.migrate
Look into the mix.exs file for futher aliases and shortcuts. You can get a list of available mix commands using mix help.
