Why it matters
This objective helps connect Simple graph-traversal algorithms to exam-style questions, flashcards, and revision notes for Graph-traversal.
Quick student answer
A breadth-first search starts at A. The neighbours of each vertex are considered in the order shown: A: B, C; B: D; C: E; D: none; E: none. In what order are the vertices visited?
Direct answer
A, B, C, D, E
Key terms
- Breadth-first search: A graph-traversal algorithm that explores vertices level by level from a starting vertex; in an unweighted graph it can find a shortest path.
- Depth-first search: A graph-traversal algorithm that follows a branch as far as possible before backtracking; it can be used for navigating a maze.
Common trap
Confusing the two traversal patterns: Remember that breadth-first search explores level by level and is used for shortest paths in unweighted graphs. Depth-first search explores one branch deeply and is used for navigating a maze.
