WebNov 4, 2024 · 2.2 Chronological Backtracking CSP can be solved using generate and test paradigm. In this paradigm, each possible combination of the variables is systematically generated and then tested to see if it satisfies all the constraints. The first combination that satisfies all the constraints is the solution. 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 ). how many hours do you need to play faceit
