Anything dealing with Houdart is better than a soap opera. On CCC he chastised Vida for supposedly having parts of Houdini in Critter, and threatened a "cease and desist" letter. This from someone that copied one of the RoboLito family and claim it to be his original. It just doesn't get much ...

Pieter,

To reliably detect a 25 Elo difference you need to play at least 500 games.

If you play only 30 games the expected score is 16-14 for Houdini 2.
The 95% confidence interval with 30 games is about +/- 4 points, which means that any result between 20-10 for Houdini 2 and 12-18 for Houdini 1 ...

P.S.
Here's another interesting link: a 100 game match at 40 min/game on strong 8-core hardware with the SilverSuite. Score was 59.5-40.5 in favor of Houdini 2 Pro, the games are available for download.

As for your tests, in ...

Hello Pieter,

From my tests with many games I expect Houdini 2 to be about 25 Elo stronger than H1.5.
By playing only 30 games your error margin exceeds 100 Elo.
This means that from your results there are no real statistical grounds to claim that H2.0 is stronger than H1.5 at fast TC, nor the ...

Anybody know what these are ??

Are there Houdini derivatives already ??

_op seems to be the stronger of the 2 , maybe ??

I'm testing _op against regular Houdini 1.5 now ......... the evals look wild , but , bottom line is after only 22 games _op is + 6 ..........
These versions have been ...

Like the two earlier replies, your reaction is completely off-topic for this thread.
It's a sad day for a forum when even the grand moderator feels the irresistible urge to make counter-productive, off-topic interventions.

Peterpan, Houdini is not a "modification of Ivanhoe" nor "open source".

If every of my replies is going to be followed by an incorrect, off-topic speculation about Houdini, it becomes very difficult for me to interact efficiently with this forum.

Peter,

"As far as I know" is a polite and respectful way of saying that the other person is wrong, hinting at some doubt so that the other's person's honour is safe.

On the other hand, your reaction is neither polite nor respectful, nor very relevant to this topic. Please be so kind to stop your ...

Anthony,

As far as I know Houdini doesn't adapt its playing style to the opponent.

The reason for not using "contempt_analysis" is that it produces asymmetric evaluations - the evaluations are slightly skewed in favor of the player having the move. If you would analyze a position with White, then ...

The maintenance update Houdini 1.5a is available, see http://www.cruxis.com/chess/houdini.htm .


Why is there such a big differene in files sizes (966kb for 1.5-w32 and 1.59Mb for 1.5a-w32)?
Houdini has a special multi-threading architecture in which each thread has its own code. The more ...
