    New Mathematical Models of N-Queens Problem and its solution by a Derivative-Free Method of Optimization
    (Science International, 2015) Ali, Javaid; Muhammad Saeed; Tabassum, Muhammad Farhan
    Most of the optimization methods do not inherit convergence proofs. One of the measures to rank them is their potential to solve challenging problems specially formulated for this purpose. In this paper the problem involves two main issues. Firstly we present new formulations of the N queens’ configuration problem as optimization problems and secondly we modify a derivative free method so that it may be able to find the optimal configuration of the chessboard.
