The N-Queens problem is one such problem with many possible configurations and realizing a solution to this is hard as the value of N increases. Reinforcement Learning has proven to be good at building an agent that can learn these hidden patterns over time to converge to a solution faster....
queens on an NxN chessboard so that no two queens attack each other, for which solutions exist for all natural numbersnexceptn=2 andn=3. A solution requires that no two queens share the same row, column, or diagonal. It is more general form of initalEightqueens problem,where we need t...
}/* This function solves the N Queen problem using Backtracking. It mainly uses solveNQUtil () to solve the problem. It returns false if queens cannot be placed, otherwise, return true and prints placement of queens in the form of 1s. Please note that there may be more than one ...

problem.In 8-Queen problem,the goal is to place 8queens such that no queen can kill the other using standard chess queen moves.So,in this paper,the proposed solution will be applied to 8-Queen problem.The solution can very easily be extended to the generalized form of the problem for ...
