Take a look at this 'KQRRN vs kqbp' mate in 4 chess puzzle created by Chesthetica using the relatively new computational creativity approach called the 'DSNS'. Chesthetica is able to generate various types of mates and study-like constructs and also compose problems using specific combinations of pieces fed into it (such as using only a queen vs. rook and knight). Learn more about it on ChessBase. The largest endgame tablebase in existence today is for 7 pieces (Lomonosov) which contains over 500 trillion positions, most of which have not been seen by human eyes. This problem with 9 pieces goes even beyond that and was therefore composed without any such help.
