I remember when Ruffian appeared in the Leo Dijksman tournaments.
For me (and I think for everyone in general) it was an "impact", he won his tournament very easily, something that had not happened before, at least that's how I experienced it. If I remember correctly, the version of Ruffian was 0.7.6 (or something like that), it was a private version that I think some beta testers had but it was not made public, which I regretted because I've always been a Ruffian fan. .
Until then most of the engines had a progression (no very strong engines appeared out of nowhere) and that's why, as I say, for me, it was a shocking appearance, since that first version that I saw in the Leo Dijksman tournament was very very strong.
Nowadays, with all the sources that are available to see, the strange thing is to see a new engine that does not have a very high level or that improves little by little, but at that time (before Rybka appeared) it was not normal to see this.
What was the top Chess engine before it was Stockfish, Komodo or Houdini?

Even if it were relevant, the data about the PAL/CSS Freestyle Tournament, isn't correct; this is what actually happened in the first edition (6/19/2005):Uri Blass wrote: ↑Wed Oct 24, 2018 10:14 amI think that super computers are not relevant for this discussion that is about engines and not about the best chess machine.yurikvelo wrote: ↑Wed Oct 24, 2018 9:36 amFor full story, one must admit, that before ~2006 there were 2 chess engine universes:Eelco de Groot wrote: ↑Wed Oct 24, 2018 12:29 am A nice list for sure, but where is Kaissa and where is Sargon
1) supercomputers
2) home computers (before IBM PC - called "microcomputers")
Supercomputers were owned and operated by big companies, played a few games and were not available to public - neither software nor access to run hardware. And they dominated up to Hydra, up to 2006.
Advances both in software (Fruit, Junior, Shredder and Fritz) and hardware (dual-core Pentium arrived in May 2005, DDR2 memory arrived in 20003, 3 GHz broken late 2002 etc) enabled home computers to beat supercomputers.
In Feb 2005 Hydra humiliated any competitors (+7 =2 -0), including Shredder and easily won PAL/CSS both in June 2005 and April 2006.
Hydra still defeated Rybka in april 2006, but later in 2006 PC-rivals become stronger and stronger (mainly Rybka) so it was obvious that "supercomputer era is over". Playing strength of Rybka skyrocketed due to advances in algos.
Intel moved to 64 bit (2004), DDR3 (2007), Core 2 architecture (2006), first Quad-core for home (November 2006 - Kenstfield) - Rybka moved to x64 (2007) and to Deep (SMP).
Fast home computers enabled engine developers to run statistically meaningfull self-play for debug and fine tuning, which in turn sky-rocketed engine strength.
The PAL/CSS Freestyle Tournament, which was held on the Playchess.com server, ended today with the finals and the match for third place. Three grandmasters, working very efficiently with support from computers and human colleagues, had eliminated all opponents of the predominantly computer kind. With one exception: dark horse ZackS with no GMs or even titled players, had made it all the way from the qualifier (required for non-titled players) all the way to the finals, leaving even the giant Hydra machines in its wake.
The result of the final was a real shocker: ZackS defeated 14-year-old Russian GM Vladimir Dobrov, working together with a 2600+ colleague (and of course computers) convincingly with a 2.5:1.5 score. A full report on both sides will follow. For now we just note that ZackS consisted of a team of two players from New Hampshire: Steven Cramton, 1685 USCF and Zackary Stephen, 1398 USCF. They used three computers for the event, an AMD 3200+, a 2.8 MHz and a 1.6 MHz Pentium. The ZackS team used the chess engines Fritz, Shredder, Junior and Chess Tiger – no GMs or IMs were involved.

My brave prediction: there will NEVER be stronger AB/cpu engine than Stockfish!

On the other hand, supercomputers are now available for a reasonable price.
I bought a 64 core machine for about $700 and a 128 core (actually 4x32) for $1700.
And the 7 nano-meter AMD stuff will be out in early 2019. I think that for a hobbyist who is a little crazy, it might be possible to get deep blue numbers on a dual AMD 128 core device.
Actually, Bojun Guo already did that. But his budget is a lot bigger than most, I imagine.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Before the scandalous ones it was rybka. Nothing could approoach the versions.
Before that were fruit derivatives, before that was shredder, before that, hiarcs had a long rule.
Chessmaster 6 had a short reign, but genius 3 had a very long reign. It was the completion of richard langs and psion legacy.
Mephisto was very hyped, but I'm not sure it was what it was hyped to be.

At one point, the dedicated machines ( and particularly many of the Mephisto units , with others, TASC etc)) were stronger than any engine on any consumer PC. That changed with the 100 Mhz Pentium CPUs and the release of Chess Genius for the PC.S.Taylor wrote: ↑Wed Oct 24, 2018 10:16 pmBefore the scandalous ones it was rybka.

Just to be clear , since the Intel brand "Pentium" is still used today, it was this CPU that allowed home computers to be stronger than dedicated machines with the PC release of Genius 2.

Yes Genius 2 on Pentium beat Kasparov in summer 1994, but even on 486 Genius 2 was stronger than any dedicated machine.MikeB wrote: ↑Thu Oct 25, 2018 3:09 amAt one point, the dedicated machines ( and particularly many of the Mephisto units , with others, TASC etc)) were stronger than any engine on any consumer PC.

People seem to forget how Fruit 2 and 2.1 impressed when being superior to Shredder 9 in 2005 up till the arrival Rybka in December the same year. Maybe it was a short period - app. 8 months, but this forum was all hot about Fruit then.yurikvelo wrote: ↑Tue Oct 23, 2018 11:13 pm 1956-1958 MANIAC I - Tube supercomputer: Could play by rules, in rare ocassion could win newbie
