Computer-Generated Chess Problem 02852

Contemplate this ‘KQRBNN vs knn’ four-move chess problem generated autonomously by Chesthetica using the Digital Synaptic Neural Substrate (DSNS) computational creativity approach. It doesn’t use endgame tablebases, deep learning or any kind of traditional AI. You can learn more about the DSNS here. Any chess position with this many pieces could not possibly have been obtained from known endgame databases. Chesthetica is therefore the real McCoy.

Chesthetica, especially if running on multiple computers or operating system user accounts, is capable of generating far too many compositions than can be published in a timely fashion here. The newer ones will therefore only be published some time later. This is why the composition date above does not match today’s date. Now, let’s see what else there is to say. Give me a moment. Why not time yourself how long it took you to solve this? Solving chess puzzles like this is probably good for your health as it keeps your brain active. Nobody wants something like early-onset Alzheimer’s.

Computer-Generated Chess Problem 02851

Take a look at this ‘KRBNP vs kqn’ mate in 4 chess construct composed autonomously by Chesthetica using the Digital Synaptic Neural Substrate AI computational creativity method. You can learn more about the DSNS here. The largest (Lomonosov) tablebase today is for 7 pieces which contains over 500 trillion positions. With each additional piece, the number of possible positions increases exponentially. It is therefore impossible that this problem with 8 pieces could have been taken from such a database.

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. Chesthetica composes only unique or new constructs. If you have seen it before, cite the source and comment below because it is purely coincidental. Try to solve this puzzle. Do try some of the others in the series as well before you go. As a whole, these problems are intended to cater to players of all skill levels.

Computer-Generated Chess Problem 02850

Take a look at this ‘KQBPP vs krb’ mate in 4 chess puzzle or problem (whichever you wish to call it) composed by Chesthetica using the ‘Digital Synaptic Neural Substrate’ computational creativity method. It does not use endgame tablebases, artificial neural networks, machine learning or any kind of typical AI. The chess board is a virtually limitless canvas for the expression of creative ideas (even by computer). Chesthetica is able to generate various types of mates and study-like constructs and also compose problems using specific combinations of pieces fed into it (e.g. composing something original using only a rook vs. five pawns). Learn more about it on ChessBase. Any chess position with this many pieces could not possibly have been obtained from known endgame databases. Chesthetica is therefore the real McCoy.

Solvability Estimate = Moderate

Most changes to Chesthetica that result in a slightly higher ‘version number’ are simply to improve the interface, by the way. White is over a rook’s worth in material but the precise win in this position still needs to be found. Did you find this one interesting or have something else to say? Leave a comment below! Solving chess puzzles like this can also help improve your game.

Computer-Generated Chess Problem 02849

Now, here we have a ‘KQRP vs kqr’ mate in 3 chess problem generated by the prototype computer program, Chesthetica, using the ‘Digital Synaptic Neural Substrate’ computational creativity approach which does not use any kind of deep learning. You can learn more about the DSNS here.

Some of the earliest chess problems by humans are over 10 centuries old but original ones by computer are very recent. Chesthetica composes everything autonomously (no human intervention) and even chooses the main line of the solution to show you. Do share and try out some of the others too. As a whole, these problems are intended to cater to players of all skill levels.

Computer-Generated Chess Problem 02848

Take a look at this ‘KQBBN vs kqrbnnp’ chess problem generated autonomously by the prototype computer program, Chesthetica, using the approach known as the DSNS from the sub-field of AI, computational creativity. There is also no proven limit to the quantity or type of legal compositions that can be automatically generated. The largest (Lomonosov) tablebase today is for 7 pieces which contains over 500 trillion positions. With each additional piece, the number of possible positions increases exponentially. It is therefore impossible that this problem with 12 pieces could have been taken from such a database. The analysis presented for this study may not be perfect as it depends on the engine used and time allocated to it. However, the key move should be right.

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. Everything composed by Chesthetica is original. Do share and try out some of the others too. Collectively, these puzzles are intended to cater to players of all levels.
