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...

or diagonally. A chess board has 8 rows and 8 columns. The standard 8 by 8 queen's problem asks how to place 8 queens on an ordinary chess board so that none of them can hit any other in one move. Here we solve this problem with a genetic algorithm for a n (n is between 8 an...

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 ...
