The 2020 Contest

The Scenario: Agents Assemble II

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 edition. Replays are available.

Mailing List

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

All the important details and announcements including scenario and communication protocol specifications as well as software release announcements and bug reports will be shared on this list.

The mailing list archive is publically available.


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.
