Right now I've been fixing some bugs uncovered by recent Pachi play
and trying to finish some experiments from February. (It seems that
when randomly choosing whether to apply a certain heuristic in a playout
or not (perhaps with 80% probability or such) it may be *slightly*
beneficial to actually do this decision once per playout for all the
moves in the playout.) Nothing terribly interesting, but I'd like to
wrap up in-progress stuff and tag pachi-11.
Other than that, I'd like to mostly revisit some old stuff that really
*ought* to have worked and brought great improvements, but never did.
Maybe I'll unearth some obvious bugs with fresh mindset. :-) Generally,
I want to focus on the never-ending quest for algorithmic breakthroughs,
not small heuristic tweaks (...which is what again sucked me in last
weekend; it's tricky to resist!)

I did some proof-of-concept work on this, described at
https://github.com/pasky/pachi/blob/master/README#L151
but it's just commandline scripts, definitely not user friendly.
Pachi also has a JSON "streaming" interface that contains details on
its thought processes. And it would also be pretty easy to build
a CrazyStone-style web interface for Pachi, in principle.
However, I'm unlikely to work on anything in this category personally,
at least not as a free-time activity. I'll gladly support other
programmers that would like to have a stab on such a thing and I think
it'd be really awesome to build something like that, but for me there's
tons more work deeper down in Pachi.

I wish they'd have let me know... :)
