Computer-Generated Chess Problem 04168

Now, here we have a 'KBBNPP vs knp' mate in four chess puzzle or problem (whichever you wish to call it) composed by a computer program, Chesthetica, using the 'digital synaptic neural substrate' (DSNS) computational creativity approach. It doesn't use endgame tablebases, deep learning or any kind of traditional artificial intelligence (AI). The largest complete (Lomonosov) tablebase today is for seven pieces which contains over 500 trillion positions. With each additional piece, the number of possible positions increases exponentially. It is therefore unlikely that this problem with nine pieces could have been taken from such a database.

Chess puzzles are ancient. Some are over a thousand years old but only in the 21st century have computers been able to compose original ones on their own like humans can. Everything composed by Chesthetica is original. Do you think you could have composed something better with these pieces? Share in the comments and let us know how long it took you. Some of these problems may be trivial for you, especially if you're a club or master player, but bear in mind that chess lovers can be found at all levels of play. Therefore, do consider some of the other problems available. You can probably find something more to your taste.
