Life In 19x19

Many thanks to everybody having brought L19 back to life! It is good that updated code makes hacking less likely.

if intelligent aliens exist on another planet, the game they would play would be go.

For a game to be reinvented remotely, several game design decisions have to be made. Go (with some reasonably simple ruleset) requires a comparatively small number of such design decisions. Simpler games, such as ...

In the paper Absolute Zero: Reinforced Self-play Reasoning with Zero Data

https://arxiv.org/pdf/2505.03335

AI learns from scratch on its own to create and prove problems of reasoning incl. deduction, abduction and induction for coding or mathematics in the manner of Alpha(Go)Zero or KataGo ...

MOST of the time we do not have the situation where A>B at a lower number of playouts but B>A at a very high number of playouts.

It is my observation in Katago study that it changes the relative order of most move candidates frequently for low numbers of playouts. A>B and B>A tend to change ...

Neural net computer go is not mathematical theorem proving, that is, we do not know whether a move is perfect play. Some practical search limit is needed, although one can fill one's RAM if a particular query is important. Go tournament players' thinking time are a different consideration and ...

For this purpose, start with one joseki corner and three single stone corners. To limit the amount of study, occupy the diagonally opposite corner with a 4-4 stone. In the two adjacent corners, each choose either a black or a white stone. Either such stone is 3-4 or 4-4 (because mostly others are ...

The basics of study with Katago concern calibration with komi, numbers of playouts, precision of values and study modes.

KOMI

For every ruleset, there is a komi so that initially the winning probability is about 50.0% and the expected score is about 0.0. One can set such a komi or accept other ...

No discussions by pros that I've seen waffle on about decimal points. They are trying to see the big picture.

Almost all decisions among top candidate moves AI makes due to decimal points. Decisions due to integer differences are the rare exception.

My study with AI includes both (a humanly ...

There is a bit of increased variation up to the maximal values of the first week after repasting:

After Before Delta Item
~66.5°C 69.5°C -3.0°C GPU-Temperature
~81.7°C 109.0°C -27.3°C GPU-Hot-Spot-Temperature
~1110 2050 -940 GPU RPM

Mostly, the new temperatures are ~64.5°C and ~79.7°C. Note that ...

For some 2500h of GPU usage, its temperatures remained reasonable. Recently, however, they and RPMs increased dramatically. dGPU temperatures above 115°C are said to be dangerous for the GPU life. The hot spot temperatures of my GPU rose to 105°C and, during subsequent weeks, beyond. RPMs used to be ...

On 2025-02-27, Claudia Pechstein, 53, and ISU made an extrajudicial agreement with confidential details. Today, on 2025-03-10, she ends her career as an athlete but might become a trainer.

Another consideration is the standard of proof. Contrary to first impressions the standard of proof in sport is not ‘reasonable doubt’. The standard is usually ‘comfortable satisfaction’. What that means is that it is necessary and also sufficient if the evidence allows the decision making body to ...

Previously on Youtube I experienced some deletions of comments in computer tech channels. Now, in a go-related channel, I have experienced something new to me: a comment temporarily disappearing for a few days while being on hold for closer reading or moderation by a channel admin. Instead of ...
