Soberango 0.00.0 realized.

...
Perhaps you can contact respectively send to him debug-files (about games running Soberango 0.00.3 on WinBoard /ScidvsPC)
...

OK! Thanks! I´ll do, but actually I´m still madly involved in just playing development.

[Sylwy]

Thanks for your time Norbert and Sylwy!

...
The engine has around 410 Elo CCRL 4/40 !
...

1.-How do you know it?

2.-What is 4/40? 4 minutes for 40 moves? ¿And after move 40?

1.-Well, a long test versus Pos 1.20 engine (used like marker);
2.-I used in my test TC=5'/game. The total time per game is very similar to TC=4/40 moves of CCRL.

THANK YOU for the new version !

[Luis Babboni]

5 minutes per game?
Is what I use too as only mode for the moment.
You gives Pos 1.2 the ELO that appears here:

and see the final ELO for Soberango after some number of games?
Wich ELO do you choice for Soberango at the start?

Yes. Pos is a weak but stable chess engine. I tested it a lot ! Well, statistically the rating after a single match is not correct.......but the result is not too far. Maybe CCRL will test it !

[Luis Babboni]

I read in CCRL that actually they just test engines at least as good as the worst in this list:
http://www.computerchess.org.uk/ccrl/4040/
That is Ziggurat with ELO 1790..... too far from Soberango!

I just ended 20 5/0 matchs against Pos and the score was 19-0-1 (+676 ELO for Soberango 0.01.1 for starting in 288, the same as POS)

I use this list of CCRL:
http://www.computerchess.org.uk/ccrl/404/
Where Pos is the last and trying to play one by one from bottom to top 10 5/0 matches each and do not found all and somes do not works but nº492 Kace with ELO 975 stop 0.01.1 clearly and NSV being the stop for 0.00.3, now ended all in tie cause neither it neither Soberango knows 3rd repetition rule and none use random but with whites NSV was clearly better and slighty better with blacks.
I tried Microchess and the problem is that cause Soberango 0.01.1 lost the random ability cause the implementation of the Alpha-Beta, it plays allways the same game against some other engines that do not have random neither. Microchess is one of them and they play just 2 differents games on wich have whites and who have blacks. Both won by Soberango.

My next target, and I´ll put myself right now on that is to gave back some random to Soberango!

[Sylwy]

Here is my result after 90 games: +60-29=1 +123 Elo for Soberango 0.00.0 !

[Luis Babboni]

Thanks!

Which version of Pos you have? It seems is better than wich I use or depends on the speed of the hardware, Soberango do not depends on the speed hardware for the moment if it have enough time to complete the game.
I have a Phenom 955 at 3.2 MHz.

Wait!! I use 0.01.1, not 0.00.0.
Anyway with 0.00.0 I had 9 0 1.

Nice to see the flag and the logo in Arena, just after saw your image I went to Arena I learn how to do it!

[Luis Babboni]

LOL!! Soberango did its first tournament.... and lost all its matches!!

Thanks Dydolec for include it!! I hope new versions will have better performances in the future!

Version 0.01.3 incorporates some of the random that lose when change from minimax to alphabeta:

Plays better than 0.01.1 and 0.01.2

Well, 1st step completed.
Starting from zero knowledge, after 5 months (3 trying to understand what´s the matter included failed attempt to learn C++ and 2 in the making and tests), the very first version of Soberango see the sunlight.
It´s played some games against myself (1500 in chess.com) and in 5/0 blitz is a good opponent. Playing 10 games against the weakest engine I could found: Safrad, won 1, tie 3 and loses 6.

Comments:
-Version: 0.00.0 (Very basic winboard engine, just works and for the moment just checked successfully in Arena 3.5 and Arena 3.5.1).
-Options: there isn´t, just plays matchs from the initial position without ponder.
-Searching algorithm: just Mini-Max, no alphabeta.
-Search depth: fixed in 4 plies.
-No time management. In a Phenom 955 3.2MHz, could play Blitz from minimum time 1:30/0 losing by time very rarely.
-Evaluation: just material difference.
-Not detection of 50 moves rules neither 3rd repetition.
-Not show think.
-Known bug: if lose by time, could not start a new game without restart.
-32 bits engine.
-8x8 matrix board representation.
-Wrote in FreeBasic .

Thanks to the forum for the help you give me no matter how noob my questions use to be!

Engine a bit buggy...tends to hang and not close after games ended..(use task mgr to close) works using only wb2uci adapter in Fritz and Lokasoft...(xboard and winboard gives no moves in lokasoft)...not quite a random mover..shows some ability (tactics) reasonable strength for a new engine..(needs some work)....rating based on some swiss games
1100-1300?!?! rough guess...AR

Soberango pgn games
