N-Puzzle or Sliding Puzzle is a popular puzzle that consists of N tiles where N can be 8, 15, 24 and so on ... a time (i.e. move the empty space one position at a time). A* is a computer algorithm ...

A* ("A Star") algorithm ... solving the puzzle: So what should be the g and h cost for this problem? Since each time you just move one tile by one block, you can say actual move cost (g) is 1 from ...

Also, be aware that the time it takes to solve random 8-puzzle instances can vary from less than a second to hundreds of seconds — so solving all these problems might take some time! The algorithms ...

Abstract: The 15-Puzzle is one of the most famous benchmarks ... and Linear Conflict heuristics under an A* search algorithm to come up with a solution for the problem. A* approximates the cost that ...
