For many problems, the path to the goal is irrelevant. For example, in N-Queens problem, we don't need to care about the final configuration of the queens as well as in which order the queens are added.Hill ClimbingHill Climbing is a technique to solve certain optimization problems. In ...
No worries! If you're interested,this was the taskin question, where you are asked to come up with a sequencial way to place queens in every cell of the board, so that each queen placed cannot be hit by the previous one. As for your question, for backtracking, you can note that you...

is impossible to figure out, because the efficiency of deriving from the whole to the part is too low, this question is directly given For a local value, we must use a relatively "local method" to quickly derive the next value, so this problem cannot be solved with a backtracking ...
