+  collapsed:: true
 	- **Evaluation function** — $f(n) = g(n) + h(n)$ guides exploration toward the target.
 	- **Optimal & Complete** — guarantees finding the shortest path if $h(n)$ is admissible (never overestimates) and consistent.
 	- **Min-Heap driven** — open set selection is powered by priority queues for $O(\log V)$ node retrieval.
 	- **Dijkstra as base** — Dijkstra is a special case of A* where the heuristic function $h(n) = 0$.
 	- **Memory bound** — A* stores both open and closed sets in memory, which scales to $O(V)$ size.
