WebSolving CSPs–Backtracking Search • Bad news: 3SAT is a finite CSP and known to be NP-complete, so we cannot expect to do better in the worst case • Backtracking Search: DFS with single-variable assignments for a CSP – Basic uninformed search for solving CSPs – Gets rid of unnecessary permutations in search tree and WebBacktracking and Depth First Search. In very simple terms, we can think of backtracking as building and exploring a search tree in a depth first manner. The root node of the tree, or the "path" to the leaf node, represents a candidate solution that can be evaluated. So as we traverse through each path, we're testing a solution.

WebA backtracking algorithm is a problem-solving algorithm that uses a brute force approach for finding the desired output. The Brute force approach tries out all the possible solutions and chooses the desired/best solutions. … WebPut another way -- a naive DFS blindly visits each node until it reaches the goal. Yes, it "backtracks" on leaf nodes. But a backtracker also backtracks on useless branches. One example is searching a Boggle board for words. Each tile is surrounded by 8 others, so the tree is huge, and naive DFS can take too long.
