I used all three given chess sites on https://downforeveryoneorjustme.com/ . All are up but not accessible for me .
That's probably because you're in Iran where internet is heavily censored.

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 ...

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

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.
