What is the N-Queens problem and how can I solve it?
The N-Queens problem is a classic puzzle where you place N queens on an N×N chessboard so that no two queens threaten each other.
Can you give me an example of how to solve it for N=4?
Sure! For N=4, one solution is to place queens at positions (2, 4), (4, 2), (1, 3), and (3, 1). This way, no two queens can attack each other.
What algorithms can I use to find solutions for larger N?
You can use backtracking, constraint satisfaction, or even optimization algorithms like genetic algorithms to solve larger N-Queens problems.
Are there any known solutions for N=8?
Yes, there are 92 distinct solutions for the 8-Queens problem, and they can be found using various algorithms.
