New RomiChess released (WBEC site)

[Michael Sherwin]

thanks michael!

You're welcome Joseph!

If Tony is right and this Romi is not so good then I should have the next version ready before round 3 of WBEC div. 4.

Hi Joseph,

is the autoparalized two thread version suppose to make use of both processors?

Yes, the compiler generates multithreaded code for loops that can be safely executed in parallel.
Nothing like as efficient as dedicated hand-written smp code but should in general (depending on src code)
give a small benefit on dual-core/dual processors,

Interesting. It does not show that both cpus are running?

[Jim Ablett]

Something wrong with my standard x64 build - crashes with 'unknown win32 exception'
Sorry about that. Download this fixed one instead >

Hi Michael,

I just read the readme.txt. As a follower of Romichess, it will be sad to hear a last version. Just to show my appreciation, I also did my own comple as the released were quite slow. I didn't know Master Jim already did it as well. I've included builds to run up to Pentium1 to suite majority of users. Many people still love Romichess Mike.

I hope other learning files like from Marc Lacrosse' works in this version. Anyway, have fun with my compile too.

Yes, the learning file from Marc Lacross still works, but the one from Wael is much better.

is there a discussion of how romi chess learning works? Can the algorithim be described in a paragraph or so?

There were lots of dicussions about how Romi's learning works. Maybe someone will provide the links. I only have time for a short explaination, right now. I will write something up to include with my next release.

The 'skinny' is, Romi combines two ideas in her learn file, 1)Pavlov's dog experiment and 2)monkey see monkey do.

First, Romi remembers every move of every game for 160 ply (IIRC) and

1) gives a small bonus to every move of the winning side and a small penalty to every move of the loosing side (Pavlov)

2) Romi plays back winning lines played by herself as well as those played by her opponents (Monkey see)

so, Romi will without 'thinking' play back your own lines against you if you are good enough to beat her or her lines untill you beat her at wich time the bonus/penalty will kick in to make Romi change her play untill she finds a way to win.

Definitely the learning system works perfectly in my tournaments and the two versions of RomiChess are climbing slowly the rating list with more games played in time

Mine was never intended to be used for anything. It was just the result of the 6000 fast games experiment I ran a few years ago to prove that Mike's learning concept was statistically efficient.

It could be nice to implement this mechanism into a modified Polyglot 1.4 so that Polyglot could benefit of some kind of learning mechanism as a book manager.
