Re: Self-taught AI solves Rubik's cube.

Hello Peter: It would be very interesting to know if their algorithm could actually be trained to learn how to solve a 17x17x17 cube. The state space is very large. Just the inner pieces can be arranged in (24!/4!^6)^56 ~= 10^868 ways. My guess is that their algorithm cannot solve 17x17x17 cubes, o...

Re: Self-taught AI solves Rubik's cube

Can it beat this guy though who solves 17x17x17 cube in about 2 hours ? https://www.youtube.com/watch?v=7ChuKKL2PpU I would like to understand what makes it a unique challenge. From what I understood from the abstract - single goal state - solved in reverse with root node being that single goal sta...

Re: Banksia - Yet another Chess Tournament Manager

Hi,

Interesting project.

I tested it in Linux and it worked fine except for one compile problem. I also added CMake build files to make compilation in Linux easier. I have created a pull request that you may want to review.

Re: Droidfish 1.74 Bin-book installation

To all Droidfish (Android) users for help. I just can not bring the opening book of the SD card to work, on a Samsung Galaxy S9 + and the last Droidfish version 1.74. In the settings for 'bookfilename' the path has to be entered. For me it looks like this: /storage/0000-0000/Droidfish/book/Goi 6.bi...

Re: LC0-Leela0 for Android Devices...?

Hi Aart, Thanks for the step by step guide - I will try it! And I am so impressed because I am NOT a software man!! Thats the reason I ask for simple guides. I could NEVER write a GUI - thats another man! But I LOVE playing chess on a wooden board - using your great app! :D Peter It is easy to mix ...

Re: LC0 For Android!!! History Made!!

Tried the 64bit compile and it worked. ... Weak at tactics but plays an opening as if it is using an opening book. ... Tried to install it at different gui. 1. Droidfish, ok DroidFish has an old optimization that makes it not send the complete game history to the chess engine. Moves in the history ...

Re: Searching crazy positions

This is absolutely normal; >99.9% of the positions conventional alpha-beta engines consider belong in this totally ridiculous category. I get completely different results with Texel. ... If we consider positions with a score >= 100cp "ridiculous", it means that about 1-0.3753 = 62.5% of the positio...

Re: Searching crazy positions

When my engine searches from the starting position, I noticed that it considers board positions which are completely terrible ... Is it normal to search positions that are this unlikely to happen in a real game? Or do your engines find a reason not to go anywhere near them? It is probably likely to...

Re: Re-Pair compression questions

The decision tree is constructed by a greedy algorithm. First all possible predicates are evaluated for all positions in the tablebase, and the predicate that causes the largest reduction in entropy is chosen as the root of the decision tree. The procedure is repeated for a leaf node in the decisio...
