Hi Martin, do you have any news about new Houdini DEV version for TCEC tournament?

[Isaac]

In Gull vs Spike, the reported nodes for Gull are wrong.
It shows, for example at move 26:
Speed: 26778 KN/s
Move time: 00:03:03
Nodes:307.7 M

But if you take a calculator, and you multiply the Speed by Move time (in seconds, so 183 seconds here), you get 4904.4 M nodes, more than 10 times more than the displayed "307.7 M" nodes.
It does not happen to Spike.
What's going on here?

P.S.:Both are UCI engines.

Thursday, March 20: Chat has disappeared for me on both IE and Chrome. Is the problem on my end or TCEC's?

I have exactly the same "problem". It must be general.

Neither.

It is Chatwing that is the problem.
Not anything I can do about it until they fix it.

It's just a matter of Gull not sending a final node count update to the GUI before making the move. So the GUI uses the "last" data it sent which was probably much earlier (15 seconds?), considering it was only 307.7 million nodes.

thx Martin

I see, thank you.
