engine Rocinante is available.

[Antonio Torrecillas]

Hola,
Rocinante 1.0 engine is available (source + win32 executable)

This is an UCI engine based on the algorithm PB* .B* probability based search )
This first version is dedicated to reinvent, demonstrate, evaluate the validity of this algorithm so
it lack of the usual improvements that own modern engines (Zobrist hash + transposition table,
futility, late move reduction, end game tablebase ...) and evaluation is just the simplified UFO.

The reference used to develop PB* in this engine is B* Probability Based Search

I hope my implementation of PB* resemble the original.

Rocinante is able to fight some games against TSCP 1.81 (Blitz 2/6
+35-51=14) so milestone reached.


Happy testing, cloning...

Let me know of any issue/bug.

Regards,Antonio.

Hi,

I just downloaded it and installed it on Arena, but under author's name, it appears to show "Guillerno Filia". Are you by any chance related to him?

May be you had Chronos loaded before or Arena mixed some things up?
Chronos' author is Guillermo Filia.

There is no string with that name in the Rocinante exe,
and the uci dialogue also shows the right name
for the author.

Code: Select all

uci
id name Rocinante 1.0
id author Antonio Torrecillas
option name credit_nps type spin default 700000 min 0 max 4000000
option name ufo_eval type check default true
option name cpus type spin default 1 min 0 max 256
option name Threads type spin default 1 min 0 max 256
uciok

No, I'm the first surprised. In Arena 1.1 it show correctly.

When setup under Arena, if you choose to start from positions in an EPD file it generates illegal moves. I guess it hasn't got the uci protocol implemented to start from a specific FEN position?

I run some EPD test with, or ... are you starting a game from a position...this may be is not correctly handled. I look at this. Thanks Andy.

I've downloaded the full package of the engine,extracted the winzip file fully and placed its own folder, and installed it again. Now everything is solved.

I had extracted only the exe the first time around. Maybe Arena didn't recognize the info, and instead mixed up and showed the author name and country of the last installed engine.

Yes, I mean starting a game from the position.

I just finished reading Don Quixote so I enjoyed your choice of name!
