This is one possible solution for the 4-queens problem. For another possible solution, the whole method is repeated for all partial solutions. The other solutions for 4 - queens problems is (3, 1, 4, 2) i.e. The implicit tree for 4 - queen problem for a solution (2, 4, 1, 3) is as follows: Fig shows the complete state space for 4 - queens problem.
May 27, 2024 · 03 Jul, 2024 @ 01:30 PM. The 8 Queen Problem is a puzzle in which 8 queens must be placed on an 8x8 chessboard so that no two queens threaten each other. It is a classic problem in computer science and mathematics. There are 92 solutions to this problem. The eight queens puzzle problem was first posed in the mid-19th century.
Since Solution 12 is invariant under rotating the chessboard by 180 degrees, its equivalence class consists of only four solutions. Altogether, this page represents 92 solutions to the problem of eight queens; brute force shows that no other solutions exist. Solution 1. Solution 2. Solution 3.

Finding all the solutions to the 8-queens problem can be computationally intensive, as there are over 4 billion possible arrangements of eight queens on an 8x8 board, but only 92 solutions. There are various ways to reduce computational requirements, such as applying a rule that chooses one queen from each column, which reduces the number of possibilities to 16.8 million.
The backtracking algorithm, in general checks all possible configurations and test whether the required result is obtained or not. For thr given problem, we will explore all possible positions the queens can be relatively placed at. The solution will be correct when the number of placed queens = 8. The time complexity of this approach is O (N ...
The figure on right, shows one of the possible arrangements that serve as a solution to the 8 queens problem. Images taken from chegg.com and indiamedic. There are various methods to solve the 8 queens problem. The most common being BackTracking. It can also be solved using a variety of approaches such as as Hill climbing, Genetic Algorithms ...
