The video introduces search algorithms, focusing on breadth first search (BFS) and depth first search (DFS). It explains the purpose of search algorithms and contrasts random search with BFS and DFS. BFS explores nodes layer by layer, while DFS dives deep into one path before backtracking. The video uses examples to illustrate these concepts and prepares viewers for more formal explanations in future lectures.
