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...

This paper approaches an implementation of Genetic Algorithm for solving n-Queens problem. It provides an efficient way to solve the problem than traditional backtracking method. In proposed genetic algorithm, members of the population are represented by number of chromosomes. Each chromosome is a ...
queens on an NxN chessboard so that no two queens attack each other, for which solutions exist for all natural numbersnexceptn=2 andn=3. A solution requires that no two queens share the same row, column, or diagonal. It is more general form of initalEightqueens problem,where we need t...

Comparing Python, Go, and C++ on the N-Queens Problem Python currently is the dominant language in the field of Machine Learning but is often criticized for being slow to perform certain tasks. In this report, we use the well-known $N$-queens puzzle as a benchmark to show that once ...
