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...

Re: Re-Pair compression questions

For the complicated cases, such as KRNPvKQ which is the largest 6 man WDL table, the decision tree is a lot less efficient at reducing the compressed size. The KRNPvKQ table is reduced by around 30% by the decision tree prediction. Other "complicated" tables are reduced by around 30% to 50%. Do you...

Re: Re-Pair compression questions

I think it's worth to try using ANS with probabilities delivered by convolutional neural network fed with position. I tnink well-trained CNN is able to deliver almost exact evaluation which could dramatically reduce memory usage... How are you going to run an NN on all the positions in a 7-piece ta...

Re: Please Help for fix motion in all games across movements.

Unfortunatelly I dont know how to put motions in al these games or examples here into the post. Here are the games surrounded by pgn tags to make them viewable directly in the web browser.
