Computer-Generated Chess Problem 02127

Published online for the first time, consider this KQRBB vs krrn mate in 4 chess problem generated by a computer using the relatively new computational creativity approach called the 'DSNS'. Chesthetica is capable of composing positions that may otherwise take centuries or longer to arise in an actual game; so you can enjoy them right now instead. 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. instructing it to compose something using perhaps two queens vs. four rooks). (Read more about it on ChessBase: https://en.chessbase.com/tagged?tag=Chesthetica). Noteworthy here is that a chess position with over 7 pieces could not have been derived or taken from an endgame tablebase because 7 pieces is the present limit.
