Webcated. Non-chronological backtracking has the potential of significantly reducing the amount of search. However, we observe that the non-chronological backtracking may erase the satisfying assignments of the previous search by lacking component analysis, which results in solving some compo-nents multiple times and consuming more time … WebThe backtracking algorithm traverses this search tree recursively, from the root down, in depth-first order. At each node c, the algorithm checks whether c can be completed to a valid solution. If it cannot, the whole sub-tree rooted at c is skipped ( pruned ).
