AsyncHow (PDDL2.1 Formalizer): leaderboard
AsyncHow asynchronous planning (Lin et al., 2024) as run in Robust Asynchronous Planning via Auto-Formalization (Zhang et al., 2026): 320 WikiHow-derived plans with step durations and precedence constraints. Here the LLM writes PDDL2.1 files that the OPTIC temporal planner solves, zero-shot at temperature 0; makespan accuracy in percent, higher is better.
Metric: Makespan accuracy (%; share of the 320 AsyncHow asynchronous WikiHow plans whose predicted total time equals the optimal makespan; the LLM writes PDDL2.1 domain and problem files that the OPTIC temporal planner solves (PDDL2.1 Formalizer); zero-shot, temperature 0). Source: arxiv.org. Saturation forecast: Estimated already saturated. 4 models tracked.
