It begins by explaining backtracking as an algorithm that builds partial candidates for solutions incrementally and abandons any partial As for the backtracking, that is accomplished simply by making sure that the function that gets called with k + 1 removes the k + 1 th queen from the board before returning; this essentially says "We've now (unsuccessfully) tried all ways of placing the remainder of the queens - based on the positions of the k queens that have already been placed. ) You may work this entirely on your own; or you may follow the hint and use some code that I provide below. So let us consider the four-queens problem and solve it by the backtracking technique. The eight queens puzzle is the problem of placing eight chess queens on an 8×8 chessboard so that no two queens threaten each other; thus, a solution requires that no two queens share the same row, column, or diagonal. com/co The document discusses the 8 queens problem and how backtracking can be used to solve it.
