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.

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 ...

You don't need a top program on that easy one.

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...

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.

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...

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. The question is how many devices are unable to run 64 bit engines. Something is wrong with the poll, cannot vote... Ah, that's why. I guess polls don't...

ct800 (no moves) That works also under Shredder GUI, I'm using that myself. However, the only Winboard version of the CT800 was V1.11 from 06/2017. All subsequent versions (i.e. also the current V1.34) are UCI only and must be installed as UCI engine. What happens when you click the CT800 executabl...
