LZ's progression

[Tryss]

It's not suprising it is stronger : it's faster.

Look at the difference in playouts you got in your matchs

[nbc44]

Edit : another 40 game match 0.15.9999 v 0.15 (#184, same conditions as before)
LZ 0.15.9999 wins 22-18
So, after 60 games : LZ 0.15.9999 wins 36-24
Not bad
If someone wants the games...

"visit" parity test 0.15.9999 vs 0.15: 193 wins, 191 losses

Code: Select all

C:\APPS\l0gpu15.9999\leelaz.exe -g -v 800 --gpu 1 --gpu 0 --noponder -t 12 -q -d --timemanage off -w C:\APPS\net\2da87ea8.gz
vs
C:\APPS\l0gpu\leelaz.exe -g -v 800 --gpu 0 --gpu 1 --noponder -t 12 -q -d --timemanage off -w C:\APPS\net\2da87ea8.gz

Nothing interesting ...
P.S. If someone wants the games...

[Vargo]

The official V0.16 just came out !

Nothing interesting ...

V0.15.9999 or V.0.16 is faster than V0.15, so, it's stronger than V0.15 at TIME PARITY, not at visits parity (your test is at visits parity...)

If you run a match at TIME PARITY, I bet you'll see a big difference !

[Uberdude]

How much faster is the question. I just did a little test on my GTX 1060 and LZ #157 in 10 seconds went from 4k playouts to 5.4k. So that's about 35% speed increase, nice!

Someone posted this at github about the improvement LZ 0.15 --> LZ 0.15.999

So, it seems you're about right !

And time parity is the correct way to measure.

However ENOUGH time (realistic time) can be critical also. A program that might be better than another at unrealistic short amounts of time but dos not improve as much when given a more realistic amount of time as the second program is not necessarily the stronger at REALISTIC time.

We really should be making some decisions about this. What would be realistic for human blitz games? What would be realistic for fast (but not blitz) human games? What would be realistic for normal speed human games?

New network (185)
20 game match between #157 (best 192x15) and #185 (best 256x40)

LZ 0.16, 5 min per side and game, GPU 1x1080, twogtp 1.4.10

#185 wins 12-8 (6 wins as B, 6 wins as W)

Average length 227 moves , almost exactly 2 sec/move for both sides.

I'll upload the games if someone wants them.

I'm following Leela's progression with delight. Does anyone know what its current rating against human pros on "normal" hardware (let's say one GTX 1080) would be? Is it better than the #1 human on those conditions? If so, by how much?

[Mike Novack]

AND normal time. A human player could do little to no reading at 2 seconds/move.

Considering that even a few months ago, LeelaZero was beating human professionals with 2-3 handicap stones, which it was not even built for, on consumer hardware. (Since then, there has been various improvements to handicap play)

I would think that LeelaZero is well above any human on a GTX 1080. It is possible that you can find a blind spot with a ladder or similar though, depending on the time settings.

[splee99]

I run two games with equal thinking time (20 seconds per move) between Phoenixgo(W) and Leela zero(B) with weight 186. LZ lost both games.

[splee99]

LZ weight 185 is better against Phoenixgo.

P.S. Games #22 & #34 are the top of artificial intelligence .
What/where are we doing/going?

What is your GPU ?
