    My code worked successfully for all the games, but still no score? Can anyone know why?

        After comparing different heuristics, I found that the best performance was given by this cost function

        steps_from_start + manhattan_dist + sqrt(nb_misplaced)
        
        • steps_from_start: length of path taken until current state
        • manhattan_dist: distance between each cell's position versus end position.
        • nb_misplaced: number of tiles incorrectly placed

        Solved in 20 moves after finding 667 states and navigating through 396 of them.

          Played with matplotlib to generate a video solver for the sliding blocks:

            I used this formula but with or without sqrt(nb_misplaced) I still miss test 5

              I have the same problem. All the test cases have passed except the Game 5. I do not know why. (Game number changes but always one case fails.)

              Is h(s) = (manhattan_dist + sqrt(nb_misplaced)) admissable??? I don't think adding the sqrt(nb_misplaced) is necessary, or even efficacious past the constrainted tests we have.

              When I run my code, my output shows up in the "Output" column beside the input in the "Input" column briefly, but then it all disappears and an empty "Error" box appears while the puzzle animation continues. Once the animation finishes showing the 24 moves output by my program (which solve the puzzle), it says "You have lost the game". As expected, when I submitted my code, I lost all 6 games. I'm not sure why the "Error" box appears and why it's empty and I assume that this is preventing my program from winning the game.

              Any ideas about what I should do? Thank you!

              (fyi I used A* graph search with the number of misplaced tiles as the heuristic)
