    Unhappy Need help with bounding functions!

    To whom it may concern:

    I have a homework assignment that requires a backtracking algorithm to find the minimum cost route from one starting city to all the other cities along the route and then back to the starting city. It requires that I use a bounding function to reduce the search space. I'm not really clear on what the bounding function is supposed to do. I know that it is supposed to "kill the live node" and reduce search space some how. I'm just not clear how. I would just appreciate any simplified explanation of how this function works so that I can try to write the code for it.

    Thank You!!!!!!!!

    This is hard to explain. Not because it is difficult but because you really need a visual. Look up stuff on the "huffman compression algorithm" on google. You this will give you the sort of visual you need. Okay, now for some explaining. The idea here is that one path is always going to be longer than another except for the shortest path. If you compare each path to each city soon you will find that one is shorter then the next one. You simply keep evaluting until you find which path was shortest.

    No problem. I'm wasn't very specific but I wouldn't want to take away from the learning experience.
