Hi,
The new alphazero paper of DeepMind about chess and shogi has been published in
Science:

I believe that the dependence of C(s) (formerly c_puct) on N(s) is new.
The file pseudocode.py in the supplementary download sets c_base to 19652
and c_init to 1.25.

Interesting, thanks. I had not found pseudocode.py.
It is in that file:

The link is at the bottom of that page:

What exactly is the innovation that is patented ?
Using short look-ahead searches for tuning evaluation functions ( in this
case a neural network ) is not exactly new.

So far it just looks like an application (and I don't think it will be be
difficult to oppose, if you care about this)

More games in general. looks like more chess games than previously
available(wasn't it previously just 100, now it is 210)
and it looks like they addressed the flack they got from the chess

Remember, patents are a STRATEGIC mechanism as well as a legal mechanism.
As soon as a patent is publically filed (for example, as utility, and
following provisional), the text and claims in the patent immediately
become prior art globally as of the original filing date REGARDLESS of

What's insane about it?
To me, what Jim O'Flaherty stated is common sense in the field of patents,
and any patent attorney would attest to that. If I may add, Jim's last

patent". The difference is huge, and this may be in the
