Participate

There are two ways to take part: enter a planner, or contribute a benchmark domain. You can do both.

Entering a Planner

  1. Register before the registration deadline (see the timeline). Write to pascal.bercher@anu.edu.au, mohammad.yousefi@anu.edu.au, jakub.med@cvut.cz and bartak@ktiml.mff.cuni.cz with:
    • the names and email addresses of your team members,
    • the planners you want to enter, and in which tracks,
    • how many repositories you need,
    • any software your planner depends on that cannot be freely redistributed, such as a commercial solver.
  2. Develop in the repository we set up for you. We will test your planner on sample problems, so you see problems early. The repository also holds your log-check script.
  3. Until the Feature Stop, you can change anything. After it, only bug fixes are allowed. See Feature Stop and Bug Fixes.
  4. Submit a two-page abstract describing your planner, due after the Feature Stop. See Planner Abstract.

What counts as a planner, how many configurations you may enter, the resource limits and the output format are all in the rules.

Contributing a Domain

You do not need to enter a planner to contribute a domain. What a submission contains and how domains are selected is described under contributing a domain.

Questions

Write to pascal.bercher@anu.edu.au, mohammad.yousefi@anu.edu.au, jakub.med@cvut.cz and bartak@ktiml.mff.cuni.cz, or ask in the track’s Slack channel:
