Here is a screenshot of the latest version of A* Explorer (v1.1). It shows
all of its features, including:
Dynamic search space indication (red/blue squares)
Node highlighting (blue square w/magenta arrows)
Breakpoints (Red circle between O and D of Flipcode)
Open/Closed list viewing
Drawing your own large maps.
A* Explorer should be one of the most comphrensive A* learning tools out
there. A* is very important to AI game developers, so I thought you'd all
appreciate this. Plus the source code is available for download, along with
the binary and help files at http://www.generation5.org/ase.shtml.
Comments and improvement suggestions are very welcome!
