So far, there have been many different algorithm of eight queens problem. A similar sieve algorithm is presented in this paper:Using a algorithm similar to the sieve method in number theory:place the first queen in the first grid of the first row, and mark out the row, the column, the ...
Previously,lots of work is done on this problem.K.D.Crawford in [2],applied Genetic Algorithm and have discussed two ways to solve n-Queen problem.Ivica et al.provided a comparison of different heuristic techniques in [1].The techniques include Simulated Annealing,Tabu Search and Genetic ...
I'm trying to solve the problem of positioning N queens on NxN board without row, column and diagonal conflicts. I use an algorithm with minimizing the conflicts. Firstly, on each column randomly a queen is positioned. After that, of all conflict queens randomly one is chosen and for her...
在N*N的方格棋盘放置了N个皇后,使得它们不相互攻击(即任意2个皇后不允许处在同一排,同一列,也不允许处在与棋盘边框成45角的斜线上。你的任务是,对于给定...

This article tries to solve N-Queen problem by Depth First Search (DFS) algorithm and show result visually in chess board. Background As is the case with all such problems, the 8–queens problem is posed as an example to be used in discussing search methods, not as a problem that has ...

The n-queens puzzle is the problem of placing n queens on an n×n chessboard such that no two queens attack each other. Given an integer n, return all distinct solutions to the n-queens puzzle. Each solution contains a distinct board configuration of the n-queens' placement, where 'Q' ...
