this engine is geared toward (and has a lot of code for) modern intel family processors...

i intend to make a different compile but it takes time...
please be patient...
(dont forget i'm producing this engine in my free time)

kranium, I might hold an IPPOLIT VS THE WORLD match (If Ippolit is the correct term, I don't know)

Do you think the 10 best engines in the world can beat the 10 best ippolit-based engines?

"The open-source development of Fire has officially ended, and it is no longer available for download."

Hmmm, what is the difference between Fire and RobboLito2? wink

Hmmm, what is the difference between Fire and RobboLito2?

Good question...
well, for one, Fire had many features that Robbo does not:
multi positional gain (for each CPU/core/thread)
multi history (for each CPU/core/thread)
old and new robbobase support (up to 6 piece endings)
70+ UCI/fire.cfg options
random configuration generation
optional timestamped I/O log file
and more...
it's fatter and slower

Robbo is much faster, highly optimized for speed, and is considerably stronger (probably +30 ELO or more, test it yourself)
it does more agressive pruning
material values, search and evaluations are are also quite different:
for ex: here's a random position:
http://www.chesslogik.com/Robbo_vs_Fire.jpg

there are also similarities, of course, having both been developed from Ippolit source code,
but they lie under the surface, and are pretty hard to see, IMO
i.e. basic functions like hash tables, SMP algorithms, move generation, etc.
take a look at the source code if you want to know more
