Re: create log on android

If the directory the engine is in doesn't allow write access, then you can't create files there. This behaviour is the same under any Linux, not just Android. So the first thing is checking what the file permissions for this directory are.

I started here a discussion where I try to understand the basics of bitboards. I would like to make a kind of tutorial, with Pascal code examples.
Discussing a LISP implementation in Finnish would be even more effective in limiting the number of participants. :wink:

Re: Creating a spoon of TSCP181

What are the thoughts about this process? 1. Given TSCP's licence, it sounds pretty much like a copyright infringement. 2. You cannot re-licence a derived work. 3. It is still a fork, technically. 4. You already have an engine up and running that is 700 Elo above TSCP, so what's the point? Why not ...

Re: CCRL 40/40, 40/4 and FRC lists updated (23rd February 2019)

That is a surprise for me. Any particular reason ? 1) the market share of desktop Linux is negligible in general. 2) application deployment under Linux is bad. You can't just make an EXE on one distro and hope that it will work on another distro - and there are hundreds of distros around in a compl...

Re: Singular extension ... again

Maybe that's a re-adjustment of the score? Some engines give a bonus for delaying bad positions and a malus for delaying good positions, so that's how a depth and a score could be tied together.

Re: understanding android chess engine binary formats

Basically, you have Android in 32 bit, that's the armv7 executable. And then in 64 bit, that's the arm64 ones. The arm64-pgo is optimised after profiling, so it is faster than the normal arm64 one, but the arm64-pgo has the drawback of being twice as large. All of them are for ARM CPUs, which are th...

Re: Which Android engine support do you want?

many have arm32 , many chess engine are available for it but now arm64 device is present Actually, from August 2019, 64 bit apps will be mandatory.
