No work has been done since last summer, this is probably the mysterious 1-core engine of "considerable strength", mentioned earlier as yet another teaser.

It's developed for TCEC, but doesn't support MP or plays there a MP-Version?

Re: Hakkapeliitta TCEC, dev relase/MAC Version
Thanks for the Mac build, works pretty well for me, giving me some crazy entertaining games! (If any engine needed a gambit opening book, it is Hakkepeliitta!)
It doesn't work well with short increments, though. I'm finding that it loses half of its drawn endgames on time when the increment is only 1 second. It makes me wonder how you are getting it to work in your super-short TC tournament. Here is a profile of its thinking times for the last ten moves in one such 5+1 game:
1.0 1.0 1.0 1.1 1.0 1.2 1.3 1.1 2.2 1.2
Hakkepeliitta needs to make its time allocation more conservative, apparently.

I am completely tied up for the next couple of weeks but after that I intend to complete the MP version, no matter what.neelbasant wrote:When will the MP version be out ?velmarin wrote:Binary TCEC, for those who like

I haven't had any time losses at short TC, or any time control for that matter. What you are experiencing is a bug which I have been trying to find for two years. People have reported this behaviour a few times, but I have never been able to replicate it. If you could send me a few PGNs of such games, or some way to cause such timeouts it would be much appreciated.IanO wrote:Thanks for the Mac build, works pretty well for me, giving me some crazy entertaining games!

Re: Hakkapeliitta TCEC, dev relase
Aaaaand right after I write that I am able to replicate the bug. Typical. Basically, it is a combination of high search depths, the hash table working as it should and checking for time only after 10000 nodes have been searched, and not the time allocation. The fix seems to be rather simple as well. I'll add a new binary soon.
