这是Java 中著名的 N Queens 问题的实现。 这使用了递归回溯的概念。 此类使用辅助函数 place(),如果可以将皇后放置在给定的坐标中,则该函数返回 true。 positionInRow - 该数组将保存放置的皇后的列值,其中单元格的索引将指示行值。 您可以在 main() 函数中更改 gridSize 的值,并获取任何给定网格大小的放置...

If you are interested in java programs for other board games likeSudoku Checker,Tic Tac Toe,Snake N LaderandN Queen Problem, you can check out my posts in Board Games section. Sudoku can be solved usingrecursive backtracking algorithm.For other Backtracking algorithms, check my posts under sectio...
The process to print the subsets of the set is a problem of combination and permutation. To get the result we use the backtracking process. Let,f(i) = function to insert the ith number into a subset. Here, we take a subset of that set in our consideration and consider two things, ...
Basically we do three things: Choice Constrains Goal For example, consider the SudoKo solving Problem, we try filling digits one by one. Whenever we find that current digit cannot lead to a solution, we remove it (backtrack) and try next digit. This is better than naive approach (generating...
