WebJul 16, 2024 · A heuristic function for the 8-puzzle problem is defined below: h (n)=Number of tiles out of position. So, there is total of three tiles out of position i.e., 6,5 and 4. Do not count the empty tile present in the goal state). i.e. h (n)=3. Now, we require to minimize the value of h (n) =0. http://madrasathletics.org/artificial-intelligence-objective-questions-and-answers-pdf
WebHere, in the above example all numbers in brackets are the heuristic value i.e h (n). Each edge is considered to have a value of 1 by default. Step-1 Starting from node A, we first calculate the best path. f (A-B) = g (B) + h (B) = 1+4= 5 , where 1 is the default cost value of travelling from A to B and 4 is the estimated cost from B to Goal state.
