Houdini 1.5 beats Houdini 5 in two testsuites

[Jouni]

Quite weird. In AH_Tactics H1.5 scored 248/250, but Houdini 5 only 243. Time limit is 10s and 4 cores. Houdini 5 tactical was also weaker with 245. In AH_Endgames Houdini 1.5 got 245 and Houdini 5 240 - and 1.5 was without tablebases also!

[Colin-G]

This is just example how useless many testsuites are! BTW Houdini 3 Tactical scores in tactical suite repeatably 250/250.

On a small test suite of positions that I regularly use, the best results are by Critter 1.4, Houdini 1.5a and Naum4.2, all getting 19/20 correct within the time limit.
Single core used, 64bit 3700MHz cpu with fixed 15sec per position and 5sec penalty for fail.

Code: Select all

1	Critter 1.4    19/20    32sec
2	Houdini 1.5a	19/20	 40sec
3	Naum 4.2		 19/20	 70sec
4	Spark 1.0		18/20	 57sec
5	Spike 1.4		18/20	 95sec
6	Komodo 8		 17/20	 86sec
7	Booot 6.1		17/20	 97sec
8	Protector 1.8  17/20	106sec

All others were < 17/20 and Stockfish 8 only scored 13/20 in 158sec
Stockfish and Komodo still top my ELO rating list in spite of this.

[reflectionofpower]

It really does not means anything unless it is a drastic departure from standard deviation.

[D Sceviour]

Quite weird. In AH_Tactics H1.5 scored 248/250, but Houdini 5 only 243. Time limit is 10s and 4 cores. Houdini 5 tactical was also weaker with 245. In AH_Endgames Houdini 1.5 got 245 and Houdini 5 240 - and 1.5 was without tablebases also!

These results are not surprising. I like to use Houdini 1.5a for every type of analysis. It has a wide search so it does not miss very much. However width does not translate into higher elo, where depth seems more important.

[Dann Corbit]

What are the positions in your test suite?

[yanquis1972]

This is just example how useless many testsuites are! BTW Houdini 3 Tactical scores in tactical suite repeatably 250/250.

disagree. its an example of how aggressive pruning has changed computer chess. better depth & elo, but more blindspots.
