In the 8-Queens problem, each queen must be placed in a unique row. After The eight queens puzzle is the problem of placing eight chess queens on an 8×8 chessboard so that no two queens threaten each other. Backtracking is an algorithm that builds candidate solutions The main motive of this IA is to find the 8 – queens problem using backtracking algorithm. If a generated solution satisfies the constraint of the problem, it prints that solution. Two queens are attacking each other if they are in the same row, column, or diagonal. The problem is challenging because multiple constraints must be considered simultaneously. The algorithm starts by placing a queen on the first column, then it proceeds to the next column and places a queen in the first safe row of that column. The goal of N Queens Problem is to suitably place N number of Queens on an N x N chessboard in a way that there is no conflict between them due to the arrangement, that is, there is no intersection between them vertically or horizontally or diagonally. Replacement: Replace the least fit members of the population with the new offspring, ensuring that the population size remains constant. Backtracking - N Queens Problem Objective: In chess, a queen can move as far as she pleases, horizontally, vertically, or diagonally.
