DayDreamer : hackers wanted

[Olivier Deville]

Hi all

Since the project is open source and the author has no email address where to complain at, it would be nice if somebody manages to fix the engine so that it won't lose on time anymore at 40/x time controls.

I got it so that at least it will compile with Microsoft and Intel compilers:
http://cap.connx.com/chess-engines/new- ... dda5009.7z

Someone else can take it from there.

The original version requires a C99 compiler (which are hard to come by as hen's teeth).

[Dann Corbit]

I made an update. The hash code did not work properly in 64 bit mode (an int value cannot hold 4 billion, so I changed size calculations to use size_t). I also changed the code so that Win64 users can allocate up to 8GB, Win32 users can allocate up to 2 GB, and Posix users can allocate up to 4 GB (the old size limit).

[Dann Corbit]

Looks like there may be some problems with other internal calculations, because hash is reported as 162% filled.

Many thanks Dann !

It seems your compiles are from DayDreamer 1.4, when latest version available is 1.5

Did you do anything about the time control management ?

Aaron Becker just released DayDreamer 1.51.

* hash sizes above 2GB should now work (not adequately tested yet
because my laptop doesn't have enough memory, but it at least doesn't
fail an assertion any more)
* hash occupancy is correctly reported (that was a left-over from when
i transitioned to multiple hash entries per key)
* time forfeits are now much less likely in "x moves in y seconds" scenarios.
