Computer-Generated Chess Problem 02251

Now, here we have a 'KRRNPPP vs kqrp' chess problem generated autonomously by the program, Chesthetica, using the 'DSNS' computational creativity approach which does not use any kind of machine or deep learning. Chesthetica is able to generate mates in 3, mates in 4, mates in 5, study-like constructs and also compose problems using specific combinations of pieces fed into it (e.g. to compose something using a rook, bishop, knight and three pawns vs. a queen and a rook). (Read more about it on ChessBase: https://en.chessbase.com/tagged?tag=Chesthetica). Any chess position over 7 pieces could not possibly have been derived from an endgame tablebase which today is limited to 7 pieces.
