A* pseudocode

There is pseudo-code in the Wikipedia article about A* search... Is there anything wrong with it? Perhaps you can explain what part of what you have read you don't understand.

this is a pretty simple and solid tutorial, it's what i used to initially learn the algorithm.

If the thousands of A* tutorials (complete with pseudocode) already on the internet can't help you, why should a fresh summary here help you any better?

I recently post the code of my implementation in c.
The most useful links (besides wikipedia):

You can find my post with the code, limitations etc, here:

Good luck.
