Webahead in the search tree of a CSP and check the status of domains of variables, and if one of these domains has been annihilated—all of its possible values have been eliminated— to begin backtracking earlier. Forward checking has proven to be one of the most effective methods of speeding up solxing CSPs, and our results supported this. WebThe code in nqueens-csp.lisp is a good guide for what's needed. Apply plain backtracking to your CSP and show that it works. 10. (5) Now instrument backtracking-search so that it counts the total number of guesses made.

http://aima.cs.berkeley.edu/python/csp.html WebBacktracking is a class of algorithms for finding solutions to some computational problems, notably constraint satisfaction problems, that incrementally builds candidates to the solutions, and abandons a candidate ("backtracks") as soon as it determines that the candidate cannot possibly be completed to a valid solution.
