Wanted engines with UCI_Elo

[Ferdy]

Blackmamba is all right but Hamsters forfeits on time all its games.

Does Hamsters hang on the second move? I should have warned you that you need to specify "-threads x" as a command line parameter. (Without the quotes, and x is the desired number of threads.) Give that a try.

Thanks, Hamsters is now running around .

Hamsters is strong

I apologize again, it's been a while since I configured Hamsters, and I'd forgotten some of the quirks of the settings.

If you leave the blunder setting on the default setting of "disabled", it will play very strongly. I usually set blunder to either "normal" or "medium".

The strengths of the blunder settings, from strongest to weakest are:

Very hard
Disabled
Hard
Normal
Medium

(There isn't much difference between the Normal and Medium settings.)

What is your recommended values such that DanaSahZ will play at a level close to human with fide elo rating 1200?

I have run DanaSahZ with that setting, and the result so far is,
7-round swiss, TC 40moves in 3 minutes repeating, ponder off.

A user who wants to play as a human only has to put elo_type human and select the elo. (The diff parameters are rather internally and should not be modified by the user to do things so complicated).

With this configuration the engine will be weaker than your configuration, approximately (466 +70) / 2 = 268 points. A human will be eternally grateful

Another thing I do is limit the number of plys of the openning book with the elo (elo/100). With Elo 1200 engine play the first 12 ply (6 moves)

[styx]

Texel from the very talented Peter Österlund is also strength adjustable (but does not support UCI_Elo)

but maybe it is not useful for you, since its strength adjustment parameter does not have an Elo reference (0 (random legal moves) - 1000 (full strength))

[mar]

What I have so far are the following. Tell me if you know of other engines .

Just a simple note regarding strength limit in cheng4, I found a bug recently (forgot to subtract elapsed time,
was 1+penalty_time_multiplier instead of penalty_time_multiplier),
so now it should be a tiny bit stronger in strength limit mode).
Fixed version can be found at github btw.: https://github.com/kmar/cheng4

At present I put my attention on engines with settable elo figures.

The result indeed is very low, with 3 forfeits on time, 2 from SlowChess and 1 from DanaSahZ.

With this setting of DanaSahZ, what rating level in activ list is this comparable?

[mar]

Thanks but I am not successful in compiling the sources.

Uh oh . What OS/compiler do you use?
I tried the win version now and compiles just fine (there is VS2012 solution+project).
For other OSes, there are simple shell scripts (instead of makefile make_*.sh
Maybe - almost forgot, either compile all the .cpp sources except "allinone.cpp", or just that one (where everything is glue-included)
