Re: Definition of single-point eye

I think I'll be doing exactly this: it's alive if it can never be captured; [some example] is alive because it has two eyes.

(In my flyer sequence, I will cover false eyes and seki, but not bent four or thousand-year Ko.)

Definition of single-point eye

I'm writing up some "how to play Go" flyers and and want to make sure I'm being precise. How is this for a definition of a [single-point] eye?

An eye is a vacant point, surrounded [orthogonally] by stones of the same color, that can only be filled by simultaneously capturing all of the surrounding stones.

Note that this is a "real" eye, not a "pseudo" or "quasi" eye as we often use in Monte Carlo search.

Also, because these are rules for beginners, I'm only interested in one-point eyes. Under AGA (and, I think, Chinese) rules, confused players can always keep going until all eyes are one-point eyes.

I *think* this definition works regardless of whether adjacent blocks have one or two eyes. (If filling is always illegal, it certainly requires capturing all of the surrounding stones.)

Is there a horrible flaw in my definition?

Ph.D. Position on Learning Online Search-Control Knowledge for General Game Playing (Maastricht University, NL)

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Ph.D. Vacancy on Learning Online Search-Control Knowledge for General Game Playing

The Department of Knowledge Engineering (DKE), of the Faculty of Humanities and Sciences (FHS), has a
vacancy for a Ph.D. Researcher on the GoGeneral project funded by NWO and DKE. The project, supervised by
dr. Mark Winands (Maastricht University) and prof. dr. Yngvi Björnsson (Reykjavik University), aims
to create intelligent programs that can automatically learn how to play many different games at an expert
level without any human intervention. 

The domain of General Game Playing (GGP) poses many research challenges in several areas of Artificial
Intelligence, such as knowledge acquisition, heuristic search, and machine learning. A recent
development in GGP is the successful application of simulation-based search methods such as
Monte-Carlo Tree Search and Nested Monte-Carlo Search. These search methods overcome to some extent the
knowledge-acquisition bottleneck. Still, all relevant search-control knowledge required for
expert-level play must be discovered using machine-learning techniques during online play. This is a
challenging task, for which more effective methods are required than currently exist. Therefore, this
project aims to develop new and more methods for online learning of search control, which will lead to
improved search algorithms. 

++++ REQUIREMENTS

Successful candidates are expected to meet the following requirements:

- A M.Sc. degree in Computer Science, Artificial Intelligence, Knowledge Engineering, or Applied
Mathematics. Candidates expecting to graduate by 1 February 2015 can also apply.
- Proof of excellence and ambition.
- An enthusiastic and cooperative working attitude.
- Perseverance to meet the targets that are set.
- Good communicative skills.
- A strong background in programming.

Preferred skills are as follows:

- Experience with C++ or Java.
- Strong self-motivation and drive.
- Fluency in English.

++++ CONDITIONS OF EMPLOYMENT

-  PhD position for four years (full time, 38 hrs/week, yearly evaluation)
-  Gross salary ranging from Euro 2083 (1st year) to Euro 2664 (4th year) gross per month
-  Holiday allowance (8%), end-of-year bonus (8.3%)
-  Stimulating scientific environment
-  Excellent facilities for professional and personal development

++++ ORGANISATION: MAASTRICHT UNIVERSITY (UM) and  DEPARTMENT OF KNOWLEDGE ENGINEERING (DKE)

UM (www.maastrichtuniversity.nl) is renowned for its unique, innovative, problem-based learning
system, which is characterized by a small-scale and student-oriented approach. Research at UM is
characterized by a multidisciplinary and thematic approach, and is concentrated in research
institutes and schools. Maastricht University has around 16,000 students and 4,000 employees.
Reflecting the university's strong international profile, a fair number of both students and staff are
from abroad. The university hosts 6 faculties: Faculty of Health, Medicine and Life Sciences, Faculty of
Law, School of Business and Economics, Faculty of Humanities and Sciences, Faculty of Arts and Social
Sciences, Faculty of Psychology and Neuroscience.

Founded in 1992 as part of the Faculty of Humanities and Sciences, today DKE
(www.maastrichtuniversity.nl/web/Schools/DKE.htm) broadly covers Knowledge Engineering in
research and teaching. DKE comprises three internationally respected research groups, having their
foci on "Robotics, Agents and Interaction", "Networks and Strategic Optimization", and
"Biomathematics and Bioinformatics". Education programs currently offered by DKE are Knowledge
Engineering (Bachelor), Artificial Intelligence and Operations Research (both Master). DKE has been
top-ranked in Keuzegids Hoger Onderwijs (2014). With respect to both research and teaching DKE is
engaged in various national and international collaborations.

++++ FURTHER INFORMATION AND HOW TO APPLY

Informal inquiries concerning this position can be directed to dr. Mark Winands (m.winands_at_maastrichtuniversity.nl).

Applicants are asked to email a curriculum vitae and the name of at least one reference to 
Recruitmentfhs <at> maastrichtuniversity.nl with relevant vacancy number (AT2014.201) in the subject
line before 1-12-2014.

Date of November KGS bot tournament

At present, the  November KGS bot tournament is scheduled for Sunday
November 9th, starting at 08:00 UTC.  Hideki Kato has pointed out to me
that this clashes with the Game Programming Workshop 2014 (GPW-14) on
November 7th-9th, making it difficult for Japanese programmers to
enter. I therefore propose postponing it to November 16th, starting at
11:00 UTC, and probably ending at 17:00 UTC (I will be on holiday with
friends, making a start at 08:00 UTC difficult for me).

If any of you are planning to enter but find this date impossible,
please let me know soon, and I will try to find a better date.

Convert Nemesis .GAM file to .sgf

Does anyone have a file converter to convert Nemesis .GAM files to .sgf? Or have the specs on the .GAM (Binary) file format?

 

Thanks,

CGOS update

Just renewed the domain for another 2 years. TY very much donors!

-Josh

P.S.  Anyone in the group know TCL?  I'm not bad at learning new
languages (tend to be the same) but could use some TCL help.

Perhaps my #1 request is someone with a Mac.   I can rebuild the
Linux/Windows packages, but could really appreciate someone w/ a Mac
and could download the TCL/build let me email them source (or
download) and build it for distribution. If you need help perhaps I
can walk you thru it. Will definitely note your contribution!

P.S.S.   Anyone recommend some FREE 19x19 engines.  I've post once or
twice, but still didn't see a link or find info for them.  A year or
so back both 9x9 and 19x19 was available on the wiki.  I have the 9x9
now and fusing into the server while trying to respect the original
rating for anchor.  Still need some 19x19s to run since that seems the
2nd (tie w/ 1st) most used.   Kinda giving up on 13x13 till the others
are smooth.
