Re: what happened to scorpio NN in TCEC?

This tournament is becoming a bit of a mess: They were supposed to restart without Scorpio, but they just restarted and forgot the "without Scorpio" part… They did, but they aborted it after 3 games and re-started it with Scorpio in again, apparently with the same version they used for teh blitz te...

Re: what happened to scorpio NN in TCEC?

Meanwhile, the entire Div4 has been restarted, without Scorpio. The chat message is: hi everyone i am sorry to inform you Entrance Division 4 had to be restarted due to too many inconsistencies in book orders, probably as a consequence of the many crashes among other things. this seemed to be the o...

Re: what happened to scorpio NN in TCEC?

From what I gather it is not the fault of Scorpio but cutechess-cli. Apparently cutechess-cli only waits 10 seconds for an engine to load but loading Scorpio neural networks may take upto 30 seconds. It is not a problem for winboard if an engine takes an hour to initialize because the winboard prot...

Re: std::cout or printf

This is typically the result of the "design by a committee" approach: * some idiot, who just discovered namespaces, and wet his pants dreaming about them says: hey this is awesome, we should encapsulate C library in a namespace too! * someone else, likely the political kind, who knows it's a stupid...

Re: std::cout or printf

cstdio is shitty wrapper which typically includes stdio.h internally, no magic here except it injects these C functions into std namespace; so ( typically ) you end up with std::printf and also printf in global namespace, you still typically get SEEK_SET as macros and so on. So the <cxxxx> headers ...

Re: std::cout or printf

I use this for Andscacs, I don't remember why: void afout(const char *fmt, ...) { va_list args; char buffer[4096]; va_start(args, fmt); vsprintf(buffer, fmt, args); va_end(args); fprintf(stdout, "%s", buffer); fflush(stdout); } Probably because you Ctrl+V'ed it from Fruit :) This function is just e...

Re: New uci engine: Rofchade

It does pretty well :D . Rofchade will participate in the next programmers tournament of CSVN on december 1st and 2th, I am experimenting with eval to get a good version for that and was not busy with creating a new version yet. To maybe join TCEC was a surprise so I created an intermediary version...

Re: Demolito 20181029 released

Sharable link: https://drive.google.com/open?id=1hhhs3TexEJxc9rxmACry4tsFdhWW41_y Contains my tiny source change and a 64 bit Windows binary. This compile of yours has asserts enabled (I get abs(score)<MATE at depth 9 from startpos). Did you actually test it? And he didn't even compile the latest v...

Re: Demolito 20181029 released

demolito_20181029-tp.zip Someone reported a 2GB limit this compile. Cannot allocate more than 2GB. There is definitely no bug in the code, which carefully uses 64-bit arithmetics, and _aligned_malloc() which is supposed to be 64-bit according to MSDN. So, yet another compiler/libc bug, it seems :cr...
