N.E.G. 0.3 was actually a slightly modified version of my regular alpha-beta engine Joker, which was closed source. I haven't worked on that since 2008, and I am not even sure I do have sources, as this is many computers ago.

The Ram 2.0 source is below. It should be linked with the MersenneTwister random generator.
Thank you very much, for N.E.G 1.3 and for Ram 2.0.

After some research I was able to compile Ram (under Linux). :)

Here are the results of a little tournament that I have just made.

Code: Select all

Rank Name                Elo    +    - games score oppo. draws 
   1 Iota 0.1            633  138  103    48   96%   168    8% 
   2 Moustique 0.3       393  123  113    24   69%   238   13% 
   3 Alouette 0.0.9      309  114  108    24   63%   238   25% 
   4 NEG 1.3             287   81   79    48   54%   254   17% 
   5 Ram 2.0              32   79   85    48   19%   318   33% 
   6 Arminius 2017 RND     0   80   89    48   16%   326   27%

With pleasure. Unfortunately, I can't get the Linux version to work. :?

I will give it a try tomorrow under Windows.

With CuteChess POS doesn't seem to work. I tried with WinBoard. It works, but unfortunately POS always loses on time. The time control was 40/4. What I don't understand is that Iota 0.1 always loses on time too, which doesn't happen with CuteChess, even with shorter time control. :|

My Windows computer is not very powerful. At times, all the applications run in slow motion, I don't know why.

I still saw that N.E.G. 0.3 is stronger than later versions.

Just in case, you know that POS needs cmd args?

Code: Select all

POS_120 --io-mode xboard" /fd=C:\Engines\WBJAVA\POS_120

All the time. In every conversation. You must post. Something. It's like you just can't help yourself.
