The queens order returns without attacking each other.
We use "Simulated annealing".
It is a metaheuristic search algorithm for global optimization problems.
The general objective of this type of algorithm is to find a good approximation to the optimal value of a function in a large search space.The name comes from the process of annealing steel and ceramics, a technique that involves heating and then slowly cooling the material to vary its physical properties.
