Now, here we have a 'KQRNNP vs krbnp' chess construct composed autonomously by a computer using the 'DSNS' computational creativity approach which does not use any kind of machine or deep learning. 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 11 pieces goes even beyond that and was therefore composed without any such help.

If you notice any version of Chesthetica 'skipped' from one problem to the next, that simply means additional (minor) changes were made to the program before it was set to run again. Now, let's see what else there is to say. Give me a moment. Do share and try out some of the others too. Note that not all the chess problems are like this. They cover quite the spectrum of solving ability and there are thousands published already.
