Eight queens puzzle
Description:It is possible to use shortcuts that reduce computational requirements or rules of thumb that avoids brute-force computational techniques. Martin Richards published a program to count solutions to the n-queens problem using bitwise operations. These are called fundamental solutions; representatives of each are shown below. For example, by applying a simple rule that constrains each queen to a single column or row , though still considered brute force, it is possible to reduce the number of possibilities to 16,, that is, 88 possible combinations. However, this solution has already been published by Zongyan Qiu .
