WebGreedy Search • Most heuristics estimate cost of cheapest path from node to solution. • We have a heuristic function, which estimates the distance from the node to the goal. • Example: In route finding, heuristic might be straight line distance from node to destination. • Heuristic is said to be admissible if it never overestimates cheapest ... Web• Uninformed (Blind) search : don’t know if a state is “good” – Breadth-first – Uniform-Cost first – Depth-first – Iterative deepening depth-first – Bidirectional – Depth-First Branch and Bound • Informed Heuristic search : have evaluation fn for states – Greedy search, hill climbing, Heuristics • Important concepts: how many dogs are euthanized every year
