Stupid error, crazy performance boost

[xr_a_y]

After months of diagnostic, bug tracking and tuning on Weini, trying to get some strength, my eyes became blind to mostly everything ... So I used CLOP a little, and added a few elo. But nothing spectacular at all ...
Yesterday, the single threaded version of Weini, with ponder on, was "only" +150elo (69%) against fairy-max at bullet or atomic TC but was loosing badly versus Isa or Dorpsgek.

So I decided I shall take some time to read again old, basic, stuff in the code... And of course, I've just discovered something bad, very bad. In QSearch, move generation was performed too soon, before standard cut-offs... Having fixed this, I ran a match versus fairy-max : the speed boost is quite interesting of course : more than 30% in knps ; but the elo gain seems crazy : now around >80% winrate (>250elo) versus fairy-max.

Some days are needed to ensure everything is correct, but that was clearly the silly little kind of things I was looking for for months ... I feel a little better now !

Nice, a new engine! What's the current estimated strength? I might include it in next season's CCLS.

I'd be glade to participate. Weini should be around 2200 for now.

No Windoze bins? I've been unable to compile with Cygwin. Stuck at the Cmake stage, with an error about /usr/bin/c++.exe being broken.

It uses backtrace() which is Linux only and it also has lots of template substitutions that are not legal.
No way to compile it under Windows.

No issue with visual studio here. The traceback call is inside a #ifdef. Indeed, I've never tested cygwin. You can probably remove the content of backtrace function if requiered. I'll do something for the next release for cygwin.

Can you elaborate a little about this template issue please ?

On the Github page you have linked to, I only see a README file, was that intended?

g++ output is attached.
You can get a stack trace like this in Windows:

All the compile errors complain that you have defined a backtrace() that returns void, it seems. It complains on this line over and over again:

Code: Select all

             (*_os) << backtrace() << std::endl;

Nothing illegal about that, as long as backtrace() returns something that can be printed (ie., not void).
