Optimal Track

Satisficing Track

Agile Track

PDDL Fragment

We will use a subset of PDDL 2.1, considering two fragments:

Preconditions and goals are arbitrary propositional formulas. That is, they include quantifiers, negative preconditions, disjunctive preconditions and any number of numeric predicates. Conditional effects are not considered. Terms can either be literals as in classical planning, or numeric terms of the form f(X){ >=,>, =} 0 where f(X) is a linear expressions. Each domain of the competition will be either a SNP or a LNP (LNP is more expressive than SNP). Planners supporting only SNP will be accepted and their performance will be reported when compared with respect to only SNP problems. A planner can also only support SNP. We are considering to have separate rankings.

In terms of the optimisation track, the optimisation functions will always be a minimisation. Problems will either be a minimisation of action costs, or a metric function that is a weighted sum with positive coefficients where each involved variable can only be increased by the actions.

Sample problems are here: Domain1, Problem1, Domain2, Problem2, Domain3, Problem3


We require that a planner is registered through a team. For this you need to send an e-mail with a subject containing “[Registration for Numeric Tracks]” to The email must contain:

names of participants, email contacts, track (agile/satisficing/optimal), at least one github account

Based on that, we will create a private repository under the ipc2023-numeric organization and add all participants as users with with write access and participants can both upload their planner there, and then commit to the repository as they wish until the “final planner submission” deadline.

All participants must subscribe to the Google Group. We will announce further details on the submission process there in due time.

To propose a domain for the competition, please contact the organizers (see below).
