Multi-Agent Programming Contest

The 16th edition of the Multi-Agent Programming Contest

The Scenario: Agents Assemble III

Agents with limited local vision have to organize to assemble and deliver complex structures made of blocks, in a grid world.

The scenario is a revision of the previous editions, 2019 and 2020/21 .

What When
First software package and specifications available December 2021
End of Registration and Qualification June 2022
Contest July 2022


To register, submit the registration form (tbd).


In order to participate in the contest, your agents have to demonstrate a stable connection and some basic scenario-related skills. Details will be made available closer to the contest.

Connection Tests

After the registration deadline, you can contact us to schedule a connection test, where you can try out your connection to our severs (and possibly identify some issues before the qualification).

Anonymous Test Matches

You can tell us if you’d like to play test matches against other teams (before the contest!). If we find a match, both teams’ identities will be kept secret from each other. The full monitor will of course also be disabled.

The platform

The MASSim server is available on GitHub.

The package contains some dummy agents for different platforms. You can use them as a starting point or implement the communication protocol yourself.


The winner of the contest will be awarded a voucher for 500 EUR worth in books, thankfully provided by Springer Verlag. Requirements are the submission of a team description paper and the source code of the agents.


Mailing List

Participants and all interested colleagues are invited to subscribe to our mailing list:

All the important details and announcements will be shared on this list.

The mailing list archive is publically available.


You can also join our Slack community for discussions, questions, bug reports, etc.


After the tournament we invite every participant to submit a paper about their team. Once the quality of the papers has been assured, they will be regularly published (as the previous editions) in Springer’s LNCS Challenges subline.

Authors should consult Springer’s authors’ guidelines and use their proceedings templates, either for LaTeX or for Word, for the preparation of their papers. Springer encourages authors to include their ORCIDs in their papers. In addition, the corresponding author of each paper, acting on behalf of all of the authors of that paper, must complete and sign a Consent-to-Publish form. The corresponding author signing the copyright form should match the corresponding author marked on the paper. Once the files have been sent to Springer, changes relating to the authorship of the papers cannot be made.

Please answer and append the questionnaire (tbd.) to your team description paper. Also, please send us a draft version until 15 September.
