Re: UCI flexibility

Hash table size doesn't matter much because e.g. CCRL tests are usually done with 128 or 256 MB, see here: http://ccrl.chessdom.com/ccrl/404/about.html . If your hash table design requires powers of 2, then it wouldn't make sense to allocate only 128 MB when 256 MB are allowed just because you'd end...

Re: Pointers in C++, please help

Hi Ras, Thanks! How would it be done with good practice in C++? I have no clue. You'd use some of the STL provided types. You could use either a std::vector inside another std::vector, or std::array inside another std::array. I think the latter will be faster here because the dimensions are fixed s...

If you have this: *(mvs + (((fs << 3) + n))) = ts; // I want to do something like, mvs[fs][n] = ts; then the shift suggests that the n variable stretches over 3 bit, i.e. it can go from 0 to 7. That means a lower array dimenion of 8. Assuming that the other dimension is also 8 because it is about a ...

Re: Problem accessing sites

Easily said but is it true? I think it's related to https-only. I tested also my small website using https://www.comparitech.com/privacy-security-tools/blockediniran/ - doesn't work in Iran. On the other hand, Talkchess happens to work because this site is so badly maintained that it doesn't even h...

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:
