Houdini 1.02  969 861 929 905 926 933 933 890 887 933 9166
IvanHoe 57a   971 845 928 930 952 958 909 809 866 963 9111

Houdini wins here, again largely due to STS8.

[Swaminathan]

Yes, the comparison is interesting.

The engine's style seem to deviate with more updates.

[Swaminathan]

Based on the stats, I can't really say which one is better. It's still open to research and learning.
Another way of making comparison is Ivanhoe leads 5.5 - 4.5 over Houdini in 10 STS's but Houdini has more better grades.
I think STS 8 is not nearly as crucial or important relative to others but it still helps for a top program.

Is there an easy way I can get a chart of the "hardest" positions in STS, that is, those (of the 1000) that have the lowest percentage of engines that get the correct move? I suppose this is just some transposing of the available data, but I can't find anything that directly gives this on the STS website.

I don't have that data. I was wondering if making available all the log files of top engines like Stockfish, Houdini, Ivanhoe, Komodo, Spark etc could help in isolating the tough puzzles from the moderate/easy ones?

Thank you very much, Swaminathan, for the great results. That's the most comfortable way of using your suite for all of us of course, if you do it for us.

I will allow myself to set a link to your posting in CSS forum, won't I, if you don't mind.
