Source code needed for simple experiment

[Michael Sherwin]

one more thing: it seems Microsoft broke the CRT (still not fixed!) so you'll probably have to set Windows SDK to 10.x in general properties or you can simply go to main.cpp and delete the 4 lines below "disable I/O buffering".

Is that why Viper won't run in windows 10 as well?

Hmm, could be. You can try to set Windows SDK to 10.x for Viper to see if it helps.

Is source code available for a material only searcher that is simple fast and hopefully smp? I want to do a very simple experiment for a search based on statistics and material only with absolutely no positional evaluation involved.

Suggestion:
Start with Viper, and simplify the eval to have wood only.

Thanks Dann, Sounds good! I recently downloaded Jim Ablett's Compile of Viper and could not get it to work in Windows 10 under Arena. I then tried compiling Viper myself with the same result. What am I doing wrong?

Nothing, it used to work, but something has changed (probably in the Windows API) and it just hangs now.

Too bad, because your eval would have been as simple as this:

Code: Select all

int evaluate(const position_t *pos, int thread_id) {
    unsigned us = pos->side;
    unsigned them = us^1;	
    return pos->material[us] - pos->material[them];
}
