Goal is at (10, 4). Three frontier nodes have:N1: g=6, h=5 → f=11N2: g=4, h=9 → f=13N3: g=7, h=2 → f=9Which node does A* expand next?

A team is building a model that does not learn a parametric equation. Instead, it stores past examples and, for a new case, finds the most similar stored cases and predicts based on those similarities. This approach most closely aligns with
