is Leela deterministic in analysis? seems no

[Uri Blass]

I decided to analyze the initial position with rook odds by Leela twice
wtih contempt 420 and white side analysis
It seems that first iterations were the same but later I got some difference and I wonder what is te source of the difference(I do not have gpu)
first analysis

[Karol Majewski]

It's not deterministic anymore. I've reported this couple of years ago and nothing has changed since then:

https://github.com/LeelaChessZero/lc0/issues/1769

[Eelco de Groot]

Knowing nothing about Leela I think it would be natural to expect this, if the search is Monte Carlo, so that at least semi random moves get chosen for the tactical search, but I'm sure there are people in the forum who know Leela better than me

[Ryan Benitez]

If you are trying to get something close to deterministic I would hope you have Dirichlet Noise and Temperature both disabled. I have not looked at the source code the Leela in a while but I would assume that it uses asynchronous batching so timing will get you further from deterministic results. Small of timing differences can really compound move selection differences in MCTS.
