WebForward Checking (Haralick and Elliott, 1980) Variables: U = {u1, u2, … , un} Values: V = {v1, v2, … , vm} Constraint Relation: R = {(u1,v1,u2,v2) u1 having value v1 is … WebForward Checking • The idea of searching in a tree of variable assignments is very powerful. However generic backtracking is not a very good algorithm. • (Note that although BT is much faster than simple enumeration all algorithms for solving CSPs take time that can grow exponentially with the size of the problem.)
