SimulCost (Single-Round) - Medium Accuracy: leaderboard
Metric: Success rate (%) at the medium accuracy requirement, single-round mode (one parameter guess, 2,643 tasks), on 11 physics simulators with analytically defined costs (fluid dynamics, heat transfer, solid mechanics, plasma physics); a task succeeds when the proposed parameters meet the accuracy requirement; higher is better. Source: arxiv.org. Saturation forecast: Around January 2027. 5 models tracked.
