SCML · ANAC 2027 · In preparation

Supply Chain Management League

Run a factory in a simulated supply chain. Your agent negotiates every purchase and every sale, with no central market to fall back on — buy too dear or sell too cheap and the plant loses money.

Design and build an autonomous agent that negotiates on behalf of a factory manager situated in a supply chain management simulation. The goal of a factory manager in SCML is to maximize its profit given its private production capabilities by negotiating trades with other agents. A factory manager can engage in several negotiations simultaneously, for which its utility functions are in general interdependent. These negotiations, and any ensuing contracts, are bilateral. Moreover, they are private to the agents involved. For more details about the competition, please check the standard track overview or the oneshot track overview.

How to take part

Register
Create an account and a team on this site. Register here — one team per submission.
Read the rules
Start from the call for participation, then the tutorial.
Build your agent
Pick a track (OneShot or Standard), start from that track's agent skeleton, and implement how your factory buys, sells and plans. Give the class a unique PascalCase name — placeholder names such as MyAgent are rejected.
Upload it
Upload from your home page. Every upload is test-run automatically, so you see errors before the official tournament does.
Watch your score
Tournaments run regularly through the season. Track your agent on the standings further down this page and keep re-uploading until the deadline.
Submit the report
A short academic report (or a written description) is required to qualify for the finals. Upload it from your home page before the report deadline.

Getting started and getting help

The first thing you need to do is to read the game overview for the track you plan to submit to. You can check the rules for the one shot track and/or the standard track.
If you are not registered here, do so to received updates and be able to submit your agents later here.
After deciding which track(s) to participate in, check their detailed description (OneShot or Standard).
Next, Check the tutorials. You can find video tutorials and consult the documentation and we are happy to see you joining the discussions.
Next, download the appropriate skeleton (OneShot Classic, RL or Standard Classic, RL) and test it. You will find a full description on how to do that in the README as well as the docstring on top of the agent module in the skeleton.
Happy hacking :-) If you have any questions, bug reports, feature requests, etc, you can open an issue on the SCML GitHub page
