Re: [Computer-go] Zen lost to Mi Yu Ting

[Chun Sun]

How does Zen know it's playing a Japanese rule game? Can it be set to play
a Chinese rule game and hope to converge at the end?

Re: [Computer-go] Auto Go game recorder

[Chun Sun]

have you tried "justgo"?
https://play.google.com/store/apps/details?id=com.wtweiqi.justgo

it's not perfectly robust but when setup correctly, doable.

Hello everyone,

Another update, as AGA will announce later:

* We are honored to have Yuandong Tian from Facebook Research, to
present "DarkForest:
A DCNN-based open source Go engine", on 8/4 afternoon.
* We are honored to have John Tromp, who calculated the exact number of
legal Go positions, to present "The number of legal Go positions", on 8/4
afternoon.
* As previously mentioned, Deepmind is coming to USGC this year. In
addition to the opening keynote on 7/30 Saturday, Aja Huang and Hui Fan
will also present "AlphaGo Insider" lecture on 8/4 Thursday's "Computer Go
afternoon", focusing more to the developer community.
* After these exciting presentations, DarkForest will play Andy Liu 1p at 3
handicaps.
* "JustGo" live recording/broadcasting app will be demoing around the
lounge and playing room.

This should be a fun event :)

Thanks everyone who helped our community work:)

Hello everyone,

I'd like to bump up the thread and announce another team attending USGC
this summer:

Wantong Technology from China will attend USGC with their automatic game
recording and broadcasting app "JustGo". Lei Chen 7d (CEO) and Yi Tang 2p
will come to Boston to do the demo.

Here is a demo for an internal version, pretty sure the July version will
be better...

Thank you, and hope to see you this summer in Boston.

[Computer-go] US Go Congress 2016 "Computer Go Afternoon" invitation

[Chun Sun]

[Demo Stations; Poster sessions; Freestyle Q chat with anyone]

Hello everyone,

We are happy to announce that we will have the "Computer Go Afternoon"
event in the US Go Congress <http://www.gocongress.org/> in Boston this
summer. It will be arranged on Thursday, August 4th, 2016, from 2pm - 5pm. We
will have a dedicated large meeting room + hallway demo/poster stations +
white board + boards/stones for computer go developers.


This is:

   - A salon for devs to meet each other in person, hangout and talk.
   - An opportunity to ask questions and share pains about corner cases,
   parameter selections, or other random technical details with experts and
   colleagues.
   - A stage to show-off your Go related projects. It can be *any*
   interesting projects other than playing bots.
   - A chance to test your program against curious real players in any
   strength. You can find your potential test engineer with pro strength too.

This is Not:

   - A bot competition.
   - An academic conference.
   - A chance to revenge to another dev in real game if your program is
   weaker.

The afternoon will be more about connecting people. We hope everyone will
enjoy.

We already have confirmed attendance from the AlphaGo team. We are working
on confirming attendance with some other teams, I will update on this
thread with better information along the way.


You can sign up for USGC now (register at www.gocongress.org) then send me
your abstracts (or ads with pics, or videos) later. If I get your material
before 6/30, I can manage to advertise it before the congress opens.


This year's USGC also features keynote speech at the opening ceremony,
Saturday(7/30) evening, by Aja Huang and Fan Hui from the AlphaGo team.

Email me if you have any questions.

Thank you, and hope to see you this summer in Boston.

Re: [Computer-go] Congratulations to AlphaGo (Statistical significance of results)

FYI. We have translated 3 posts by Li Zhe 6p into English.

These may provide a slightly different perspective than many other pros.

Re: [Computer-go] Game 4: a rare insight

Hi Marc,

"but did not find a "solution" for Lee Sedol that broke AlphaGos position"
-- this is not true. Ke Jie and Gu Li both found more than one way to break
the position :)

Is the last requirement equivalent to dynamic komi?
