Published online for the first time, consider this KQR vs kqrnp mate in four chess puzzle or problem (whichever you wish to call it) composed by a computer using the Digital Synaptic Neural Substrate computational creativity approach which does not use any kind of deep learning.

The largest complete endgame tablebase in existence today is for seven pieces (containing over 500 trillion positions anyway) which means the problem could not have been taken from it regardless.
