A star
it is an implementation of A* algorithm with examples of its usage.
A start (A*) is the algorithm for searching the shortest path in the weighted graphs. My implementation is provided with various interesting applications, i.e. 15 puzzle.
This project is related to my other projects located at sourceforge as well:
https://sourceforge.net/projects/path-finder-qt/
https://sourceforge.net/projects/shortest-path-graph-a-star/
For detail of A* algorithm see wiki page:
