The Math Behind Your Commute

The Palindrome • 4 implied HN points • 05 Dec 25
🕹 Technology Algorithms Computer Science Graph Theory Navigation
  1. BFS explores outward from a start node in layers, so it finds shortest paths by edge count and builds a BFS tree that groups nodes by distance.
  2. DFS follows one path as far as it can and backtracks when needed, producing a narrow, deep DFS tree. Any non-tree edge in DFS must connect a node to one of its ancestors or descendants.
  3. A connected component is the set of nodes reachable from a start node, and both BFS and DFS can find this component to decide if two nodes are connected. More generally, you can discover a component by repeatedly adding neighbors of the current set until no new nodes appear.
