The REAL innovation in computer chess in recent years, which is probably something the Ippolit authors were well aware of, it massive automated testing. They basically took Rybka and re-engineered it to gain 30-50 ELO.
So to answer HG's question, I don't hink there is much that Ippo contributed and if I'm wrong nobody here is refuting me.
This viewpoint is completely unsupported by any evidence whatsoever...
ans it's sad to see you posting such claims without any proof
Please download and read report.pdf available here:
According to BB's detailed and expert analysis,
Ippolit is completely and utterly removed from Rybka...
i.e. the # of differences are enormous, and not just cosmetic
They involve critical program functionality, everything from hash routines and memory management to search and eval
the 2 programs have little in common.

So in my opinion, Ippolit was evolutionary, not revolutionary and was not a particularly remarkable contribution to computer chess - except perhaps to show what was possible. Ippolit broke the 4 minute mile so to speak. [/b]
for years Ippolit has been publishing state-of-the-art open-source C code for:
a sophisticated SMP implementation (something many programs still lack today)
a complete innovative and original full-featured tablebase solution that easily surpasses Nalimov EGTB
RAM resident endgame bitbases
Montecarlo regression analysis
sophisticated hashing routines and options
Large pages memory
Slab memory implementation and management
Positional gain and history tables for each thread/cpu
Eval and Material explanation modes
Java GUI game explorer (similar to what Hiarcs now offers)
Java GUI endgame explorer
and much more...
All of which are innovative and original implementations!
Ippolit is not a remarkable contribution?
The fact that Ippolit's role/contributions are systematicly sabotaged and downplayed by members of talkchess.com is a travesty...
It was (and still is) summarily condemned and executed without a shred of evidence of any wrongdoing...
It should be celebrated, not raped and shot
Your statements above seem to be part and parcel to the continuous and successful effort by you and others here at talkchess.com to delegitimize a fine free and open source program
