IPC 2023 will use a subset of PDDL 3.1, as done since IPC 2011. Planners must support the subset of the language involving STRIPS, action costs, negative preconditions, and conditional effects (possibly in combination with forall, as in IPC 2014 and 2018). We will also consider including domains with disjunctive preconditions and existential quantifiers, in which case we provide an automatic translation compiling these features away, and we run all planners on both variants and select the best result per instance.
Most planners in previous IPCs rely on a grounding procedure to instantiate the entire planning task prior to start solving it. In IPC 2023, we will follow in the steps of the previous IPC by including domains and problems that are hard to ground.
As in previous editions, the competitors must submit the source code of their planners that will be run by the organizers on the actual competition domains/problems, unknown to the competitors until this time. This way no fine-tuning of the planners will be possible.
All competitors must submit an abstract (max. 300 words) and an up to 8-page paper describing their planners. After the competition we ask the participants to analyze the results of their planner and submit an extended version of their paper. An important requirement for IPC 2023 competitors is to give the organizers the right to post their paper and the source code of their planners on the official IPC 2023 web site, and the source code of submitted planners must be released under a license allowing free non-commercial use.
As in the previous IPC 2018, we will use the container technology Apptainer (formerly known as Singularity) to promote reproducibility and help with compilation issues that have caused problems in the past. In contrast to the previous IPC, we will host repositories of planners ourselves. The repositories will be hosted on Github under the ipc2023-classical organization, and they will be kept private until the end of the competition when we make them public, i.e., after the competition is concluded, we plan to make all planners, domains, and all related data accessible from one place.
When a competition team registers (see below), we create a private repository (or multiple repositories if needed) and add competitors as users with write access. After the “feature stop” deadline (March 10, 2023), we allow competitors to send only a pull request with bug fixes. We will review every pull request with its accompanying description of the bug fix to make sure that no big changes or parameter tuning is committed to the repository. To help us with the debugging process, in contrast to previous years, planner authors will be responsible for detecting if the run of their planner and our analysis of the results was successful. We will add more details on this later.
This year, we will also allow to submit multiple planners to multiple tracks from a single repository (see the Planner Submission section below). So, each team will need only one repository per code-base and different parameters for different tracks can be set by providing multiple Apptainer files.
To register a team, the participants need to send an e-mail with a subject containing “[Registration]” to ipc2023-classical@googlegroups.com. The e-mail must contain:
Based on that, we will create private repositories under the ipc2023-classical organization and add all participants as users with with write access and participants can commit to the repository as they wish until the “feature stop” deadline (March 10, 2023).
Comming soon
