Re: Linux flavors - opinions

Ubuntu has gcc 7.0 by default which is fine, but CentOS 7 on the other hand comes with 4.8.5 which is a royal pain. It can't compile my fortran 2008 and c++11 codes most of the time. yum-config-manager --enable rhel-server-rhscl-7-rpms \ && yum -y install devtoolset-7-gcc devtoolset-7-gcc-c++ devto...

Re: FRC / Chess960 -- Some Lessons I Learned

#1 Move Encoding In this process I think I came across the answer to the question "Why does Stockfish encode castle moves as King captures Rook". I chose a different route, but I'll write a bit about both. The benefit, or the reason, that Stockfish encodes using KxR is because at many points in the...

Re: Pointers in C++, please help

I played around with it, and figured out how to do it with a natural array. However, I personally find the notation more confusing. u08 mvsNW[64][8]; //... u08 (*mvsB[])[64][8] = { &mvsNW, &mvsNE, &mvsSW, &mvsSE }; // ... auto & mvs = *mvsB[i]; m->ts = mvs[m->fs][j]; I also found another way to do ...

Re: Could someone do a Demolito compile please ?

Tirsa's compile was used to test it here: http://ccrl.chessdom.com/ccrl/404FRC/ Thanks for testing Demolito. I'm a surprised to see it so high in the ranking. Yet, the elo gap to SF is monstruous, which indicates that too few engines support Chess960. It's a shame, because I like 960. It's a bit we...
