Lisp: Heuristic Search A* puzzles--

Hello freelancers, I need help creating a Lisp program which will implement heuristic search A* to solve three puzzles. ("Farmer, wolf, goat, cabbage", "Water jugs" and "8-puzzle"). I will have the complete instructions attached! You are able to use code found online as long as you cite it :) I found this heuristic search for the farmer, wolf,goat cabbage puzzle I believe: [login to view URL]~luger/ai-final/code/[login to view URL] I have a very similar lisp program which implements breadth and depth first search for the same three puzzles. I will also attach that program. I hope you can help me! Deadline is in 3 days.
