Is modeled on PDDL2.1 (Fox & Long, 2003), the domain-description languageįor deterministic domains used in IPC-3. In analogy to PDDL (McDermott, 2000), which was introduced in IPC-1. PPDDL stands for "Probabilistic Planning Domain Definition Language", We created a new domain description language called PPDDL1.0, described in Has begun, but the intent of the probabilistic planning track was to createĪ set of shared benchmarks and metrics that could crystallize efforts in The other consists of planning researchers incorporating probabilistic andĭecision theoretic concepts into their planning algorithms. One communityĬonsists of Markov decision process (MDP) researchers interested in developingĪlgorithms that apply to powerfully expressive representations of environments.
