Convergence Criteria and Observability
Look up syntax, contracts, layouts, algorithms, and exact behavior.
The simulator separates a lucky hit from a solved field. A generation is considered generation-solved only when the hit rate reaches the configured threshold. The overall scene is solved only after that condition holds for the configured number of consecutive generations.
The rendered surface exposes the state variables that matter: generation number, hit rate, best minimum distance, solved streak, current target, best trajectory, ghost trajectories, wind vector, and launch velocity. The visualization is not decorative; it is the diagnostic layer for the search process.
