when I open the Laptop the program not function, there are "The code execution cannot proceed because MF.dll was not found. reinstalling the program may fix this problem". What should I do to fix it

8-puzzle code executes infinitely.

Bingo, you go from linear time to constant time. Huge performance benefits for large data sets.

Ahh, right. The object class should be smart enough to use all of the object attributes, but you may want to override it since it could most likely be executed faster. That makes sense, I missed that one. I only spent a little while looking through and editing code.

Your solution works! make these changes. Just change comment the first two line of equals and yo did not change the Code: public void equals(EightPuzzle test)[/quote] to Code: public void equals(Object test)[/quote] Now it executes withing 1 second for all the inputs. Superb optimization. Thanks*Smile
But I would like to get things clarified.
You have made the following changes :

• in astar() you changed Code: EightPuzzle x = openset.seek();[/quote] to Code: EightPuzzle x = openset.poll();[/quote] .This way you could removed the burden of first peeking and then polling.

• 
  in astar() you converted Code: if(closedset.contains(y)){ continue; } if(!closedset.contains(y)){ openset.add(y); }[/quote] to Code: if (closedset.contains(y)) { continue; } openset.add(y);[/quote] This removed the burden of calling contains two times. Instead you called it only once.

• BUT in public LinkedList getChildren() of EightPuzzle you just kept one EightPuzzle variable called unified instead of up,right,down,left. And you changed the if statements to do while. Did you make these two change to save memory or does it also make the execution faster? If yes how did these two changes make the execution faster?

Code execution problem will not allow programs to open

when trying to open any program from the desktop icons I receive the following message, " The code execution cannot proceed because C:\WINDOWS\SYSTEM32\gdi34full.dll was not found. Reinstalling the program may fix this problem." I searched the files and
this dll is showing in SYSTEM32. Do I have to reinstall Windows 10 or is there another option?
