week--3 & 4
- Uninformed Search Strategies: Uninformed search is a class of general-purpose search algorithms which operates in brute force-way. Uninformed search algorithms do not have additional information about state or search space other than how to traverse the tree, so it is also called blind search.
- Informed Search Strategies: Informed search algorithm uses the idea of heuristic, so it is also called Heuristic search. ... Heuristic function estimates how close a state is to the goal. It is represented by h(n), and it calculates the cost of an optimal path between the pair of states. The value of the heuristic function is always positive.
