We were talking about this AI problem at work the other day and I was wondering if any one out there could suggest a way to solve it in xlisp or common lisp. Any help would be appreciated. Road Map: Read a network of roads from a file with a structure like - (<pt-name> <x-coordinate> <y-coordinate>) for the locations of the points on the map and (<pt-name> <pt-name> <pt-name>) for the list of points that make up a road. The program reads this in and asks for a starting and ending point and it returns the shortest route connecting the points with respect to the known roadways. The program must use the A* algorithm as the search whatever that is. Please explain. These are lists in the file. (<pt-name> <x-coordinate> <y-coordinate>) for the locations of the points on the map and (<pt-name> <pt-name> <pt-name>) for the list of points that make up a road. Please respond by email. Comp.ai is not carried by my newsfeed. Bill --- William M. Perkins Of course we run UUCP on an Amiga! The Greenwood wmp@wperkins.UUCP +1 703 590 0207 ...!uunet!pyrdc!wperkins!wmp
