### n-queens in Fusion

In a nice post on LinkedIn by Alireza Soroudi the author presents a short GAMS integer model for the classical n-queens puzzle: place the maximal number of non-attacking queens on an $n\times n$ chessboard.

And here is the solution we get for $n=8$:
[[_ ♕ _ _ _ _ _ _]
[_ _ _ _ _ ♕ _ _]
[♕ _ _ _ _ _ _ _]
[_ _ _ _ _ _ ♕ _]
[_ _ _ ♕ _ _ _ _]
[_ _ _ _ _ _ _ ♕]
[_ _ ♕ _ _ _ _ _]
