WebKEYWORDS : Genetic Algorithm, n-Queens problem, chromosome, population, crossover. I. INTRODUCTION The N-QUEENS PROBLEM is to place eight queens on a chessboard so that no two queens attack each other. It is combinatorial problem. This problem can be stated as placing n no attacking queens on an nxn chessboard. Web17 feb. 2024 · N-Queen problem is defined as, “given N x N chess board, arrange N queens in such a way that no two queens attack each other by being in same row, column or diagonal”. For N = 1, this is trivial case. For N = 2 and N = 3, solution is not possible. So we start with N = 4 and we will generalize it for N queens.
