WebBacktracking is a form of brute-force approach that comes into play when addressing a problem that involves evaluating several options since we don't know which one is accurate and we try to solve the problem using the trial and error method, one decision at a time, until we get the desired answer. WebIt uses a recursive backtracking algorithm with forward propagation to solve the CSP problem. The backtracking procedure works like this: function Search if all variables are set, check if the solution is consistent if the solution is consistent, then we have found a solution get the next variable V for each value in the domain of V assign the ...

WebLCV help make backtracking less often in case there is a solution, but it does not help when there is no solution since every value has to be searched. In other words, if the goal is to find all solutions instead of one solution, then MCV still help effectively while LCV does not help at all.
