Life In 19x19

It depends on your strength, of course. For me, I can't even beat it with 1 playout.

When a bot knows ladder, many interesting things happen, like this one.

Don't forget the capability to play handicap games. Although the 40 block network is powerful, it basically has not much idea how to play handicap games.

Well I never heard any amateur 10 dan rank. We think we can safely put it into the professional rank range. However, it may be hard to invite any professionals to do any match with this bot. Just a wild guess, 1600p maybe around 9p.

I have attached my configuration file and I'm happy to hear any suggestions to make it better. During that game the root visits was around 10000 to 20000, while the ELF playouts was around 2000 to 5000.

I was running a match between Katago(B) and ELF(W). Yes I used time parity with 20 seconds per move. The playouts are variable, but ELF used roughly 5000 playouts per move. It looks like ELF was ahead from the beginning to the end. I didn't set any resign threshold but at the end both sides ...

For higher playouts (visits), Katago is still much weaker than ELFv2.

Zen behaved weird in the last few moves, which seem to be low level blunders.

So what is the explanation for this straight win with only hundred or two playouts? No strong opponent yet?

It is very hard to beat ELF when it plays white.

The most confusing part is to compile the cudahelpers.cu into an obj file. I made a batch file to run in command prompt with this contents:

NVCC cudahelpers.cu -c --cudart shared -gencode arch=compute_30,code=sm_30 -gencode arch=compute_30,code=compute_30 -gencode arch=compute_37,code=sm_37 ...

You are right it is a complex situation. However, Katago thought b was losing (w can play A5 to make it a direct ko). That's a little confusing to me. By the way, white just need to find a small ko threat to win the game. I would think it would be better than sitting there and doing nothing about ...

Now this is a strange game between Katago(B) and LZ230(W). Near the end of the game white played F8 so that there was a seki in ko situation.

Both sides ...

Here is a 4 stone handicap game with Leela 0.11 with 20 second per move time setting. With the same time setting Leela Zero 40b weights have only small chance to win in 3 handicap games. The obvious style of Katago is that it likes to cut and deal with multiple groups properly. It even outsmarts ...

Compared to ELFv2, Katago's handicap game style is really the best. It can play 5 handicap games ( I haven't test more handicaps yet) without any bad moves (remember ELF's ladder moves?).
