Submitting a solution 📩

Solutions must be submitted through a form opening during submission week, using the template from the data folder on Zenodo (file named masterplan). Participants can submit either an Excel file (simplest option with the dropdown options) or JSON/YAML files (for greater customisation and following the naming convention and structure detailed in Section 2.3 of the paper). An open-source evaluator will be released before the first submission deadline, enabling participants to test the compatibility of their solution in advance.

Ranking 📊

Competitor solutions will be evaluated using the four metrics detailed in the problem description: economic performance, environmental impact, reliability, and fairness.

The competition consists of multiple rounds. The ranking formula will blend weighted aggregation of these metrics with multi-criteria decision-making methods, reflecting changing social priorities and societal perspectives. This formula may vary between rounds to represent how societal values and priorities shift over time.

To simulate real-world decision-making under deep uncertainty, the exact ranking formula will not be disclosed to participants before each submission deadline. However, the ranking methodology used will be revealed at the end of each round, before the next submission opens. The final winner will be announced at the conference.

Despite the multi-objective nature of the challenge, each team must submit a single solution per round, requiring participants to identify their own compromise within this complex decision space.
