scml-agents 0.5.1

Agents submitted to the SCML competition or contributed by the community

This repository contains agents for the SCML world.

To install this package just run:

>>> pip install scml-agents

There are two ways to submit agents to this repository:

1. Participate in the SCML competition https://scml.cs.brown.edu

2. Submit a pull-request with your agent added to the contrib directory.

Please note that torch does not yet fully support python 3.11. If you face issues installing (especially on a mac), try to use Python 3.10.

Getting lists of agents

You can get any specific subset of the agents in the library using get_agents(). This function has the following parameters:

• version: Either a competition year (2019, 2020, 2021, ….) or the value “contrib” for all other agents. You can also pass “all” or “any” to get all agents.

• track: The track (any, std, oneshot [from 2021], sabotage[only for 2019], collusion [until 2023]).

• qualified_only: If true, only agents that were submitted to SCML and ran in the qualifications round will be

  returned.

• finalists_only: If true, only agents that were submitted to SCML and passed qualifications will be

  returned.

• winners_only: If true, only winners of SCML (the given version) will be returned.

• bird_only: If true, only winners the bird award are returned (new in 2021).

• top_only: Either a fraction of finalists or the top n finalists with highest scores in the finals of

  SCML.

• as_class: If true, the agent classes will be returned otherwise their full class names.

For example, to get the top 10% of the Oneshot track finalists in year 2024 as strings, you can use:

>>> get_agents(version=2025, track="oneshot", finalists_only=True, top_only=0.1, as_class=False)
