A new version of Octochess has been released.
Probably the most important change is that Octochess now follows the limits set by the GUI on the size of the transposition table and the number of threads to use, making it much easier to test Octochess against other engines under equal conditions.
- CECP and UCI: Number of threads can be set
- CECP and UCI: Size of transposition table can be set
- CECP: Support fixed move time (st command)
- Improved playing strength
- Specialized endgame evaluation
- Many small performance optimizations
You can download the new version from http://octochess.org/octochess-r4632.7z |
Thank you Tim for the new release. But unfortunately, it really doesn't work for me. Sample session
| Code: |
uci
id name Octochess
id author Tim Kosse
option name Hash type spin default 1314 min 4 max 1048576
option name Threads type spin default 2 min 1 max 2
uciok
ucinewgame
position startpos moves e2e4
go movetime 10000
bestmove e7e6
go depth 10
bestmove g1f3
quit
|
* bestmove e7e6 was returned immediately, and no search seems to have been performed (or perhaps a very very fast one with no display at all). I tried go wtime winc btime binc and same thing happenned.
* go depth 10 returned bestmove g1f3 ? who said that e7e6 should have been played ? the whole point of UCI is to not be path dependant and you specify the position and search conditions and treat each search as a new one.
* quit is irresponsive
* my task manager is not seeing 1.3 GB of memory consumption, so perhaps there was something wrong allocating the memory perhaps ? besides, 1314 MB is really not a good choice for a default value. Use something small, like a common like 16 or 32 and think of it as a common denominator for everyone (thing Octochess should be useable on a cell phone). even better is to alloc the TT at the last moment when a setoptin name Hash is issued or a go command is issued and the TT is still not allocated. this would allow it to run on small hardware and not try to alloc big memory before it is told. |
