In the second of the week, What i have learnt on this course was Uninformed Search Strategies, A search for a piece of information with going through the nodes without knowing any domain specific information. Lastly I also did some exercises regarding the new knowledge I just acquired.

This search includes several algorithms

BFS which stands for breadth-first search

DFS which stands for depth-first search

UCS which stands for uniform-cost search

IDS which stands for iterative-deepening (depth-first) search
