The classic problem of N queens, originally published by Max Bezzel in 1848, is defined like this: Place N queens in a NxN chessboard so that no queen threatens any other. As you already may know, a queen threatens another chess piece if they share the same row, column or diagonal. This website simulates a slight alteration of the N queens problem, where in a NxN chessboard we need to place M queens ( M <= N) so that no queen threatens another and additionally, all chessboard tiles are threatened by at least one queen.
