zagreus's Issues

v2.4 out ?

i just compiled the latest source by git clone and i see the uci command shows v2.4, however your GitHub page shows v2.3.1 being the latest version.

is v2.4 a development version ?

Time forfeits in uncountable quantity

Hi Danny,

In my last tournament for Zagreus 2.2.0 there were 192 time forfeits out of 576 games! I don't know if they all were caused by Zagreus but I suspect so.
Have you not noticed that before? Does 2.3.0 solve the problem?

I used Arena. Time control was 1.6 minutes + 0.8 seconds. Maybe Zagreus does not understand split seconds increment?

compilation error : solved

i see you worked on the evaluation functions .. when i compile this newest version (it says v3.0!) i get a compile error in evaluate.cpp no matching function for call to 'min' :

uint8_t pawnShieldCount = std::min(popcnt(pawnShield), 3ULL);

i solved it by :

uint8_t pawnShieldCount = std::min<int>(popcnt(pawnShield), 3ULL);

this solution i found at https://www.appsloveworld.com/cplus/100/155/no-matching-function-for-call-to-minuint8-t-int but i'm not into C(++) so this might be wrong .. probably the error is caused by the 2 parameters not having the same type.

memory problem

letting the newest v3.0 (after PR 54) play in CuteChess i see Zagreus is using too much memory : it increases after each move, upto several Gb (5.9) and i had to cancel the game to keep my PC running .. i set 128 Mb hash for all engines, most of them claim that amount of memory (a bit more) to run.

Suggestion

Could you please include version number in zip file name?

Zagreus 0.5 and 1.1.0 Hash

Zagreus 0.5 uses around 4GB of hash according to the task manager. Zagreus 1.1.0 uses 1GB. Atlhough WB GUI is set up for engines to use only 128 MB. I also tried Arena and CuteChess and the hash could not be set. Is there a way to configure it to use 128MB or less?
