Recommendation for difficult test suite

Post by fkarger »

I have seen that there are several test suites, such as HTC, ERET or ACT.
Which test suite is recommended if you want to challenge modern engines?
Is there a test suite that represents the latest state of the art?

Many thanks for your recommendations!

Here I once in a while mixed 256 positions of somewhat collective difficulty as for hardware- time needed by nowadays stronger engines.
Most of them are well known since quite a time, some aren't, some include the sources that I know, some only as for the the older one test suites I took them out of.

These 256 are meant for about 30"/pos. and 1-8 threads of modern CPUs or a 3070ti GPU for Lc0, thus I get comparable results of about 60 to 80% of solutions for the better performing ones. More than 8 threads or stronger GPUs could get less TC of course, depending on the width of the pool of engines too, regards
Peter.

Thank you very much Peter!

I'm curious to see how my engines will cope with this :)

Which test suite is recommended if you want to challenge modern engines?
Is there a test suite that represents the latest state of the art?

Many thanks for your recommendations!

Peter one question. Which engine is the best solver in your suite? Of course multicore test and MV=1.

Of course MultiPV does help most of the engines with such positions, yet this one version of Crystal's solves only 4 positions more with MultiPV=4 and even gets some less EloStatTS (Frank Schubert)- points because of a little better time- indices of single primary run.

Internal MultiPV- mode with options of Random Op. MultiPV together with corresponding parameters for Plies and Score profit especially because you can set those parameters best fitting to certain suite and hardware- TC, one of those branches holds with 8 threads maximum of 212 solutions as for the 30"/pos. with a special setting of its internal MultPV- mode, regards
Peter.

For the two Epd sets in this thread, here are my fully decorated EPD records and simple EPD with avoid move and best move:
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.

Thanks, Dann!
BTW, in the 256 pasted here
viewtopic.php?p=978556#p978556
, nr. 137 is missing a second one solution 1.(28.) Bg7, which was the original one, when it was used as Eret nr. 84. In your .epd now it's nr.109, and in the commented version both moves are mentioned. 1.(28.) Bg7 and Bg5 are both about as equally as for their WDL- chances to be evaluated and so both should be given in syntax of bm and counted as correct solutions as well.
The position originally derives from the corr. game Persson- Teichmeister 2009, regards
Peter.
