Alyce Brady CS 510: Computer Algorithms

Breadth-First Graph Traversal Algorithm. Alyce Brady CS 510: Computer Algorithms. Search: Look for a given node stop when node found, even if not all nodes were visited Traversal: Always visit all nodes. Search vs Traversal. Similar to Breadth-first Traversal of a Binary Tree
