WitrynaThe Backtracking Search Algorithm Backtrack(assignment, csp): If assignment is complete then return assignment var ← select one unassigned variable for each value in the domain of var do if value is consistent with assignment then add {var = value} to assignment result ← Backtrack(assignment, csp) if result ≠ failure then WitrynaSummary CSPs are a special kind of problem: states defined by values of a fixed set of variables goal test defined by constraints on variable values Backtracking = depth-first search with one variable assigned per node Variable ordering and value selection heuristics help significantly Forward checking prevents assignments that guarantee … bisbee courthouse
