New release of Axelrod: 4.11.0 is out.

Was just testing if that worked. I'm typing from matrix which integrates really nicely with gitter.im

Owen: has setup the UK Python association on matrix so having access to gitter here will make this better for me as I don't keep my eyes on the gitter channel as much as I should.

If anyone else would like to join our 'UK Python Community' room on matrix, you'd be more than welcome. Brief instructions are at https://uk.python.org/contact/

On Axelrod-Python/Axelrod#1391 I've made (hopefully) minimalistic changes to the docs but also there you can see I've set up readthedocs to build documentation on PRs.

From now on any new PR will build a set of built docs that we can read through (could be a helpful check to make sure new features are documented properly etc).

It's not specifically required but doesn't hurt.
Thanks for opening the PR, (I've taken a look, not entirely sure why the CI has fallen over, probably an update to mypy).

Apparently, game theory is simple...

A former Conservative campaign headquarters insider concluded that No 10 was viewed as “pretty vindictive” by Tory MPs wary of scuppering their chances of promotion pretty, adding: “Once you’re in the cold you’re rarely going to come back in.” Another Tory aide said it was simple game theory. “Yes the odds of a reshuffle are slim, but are you really going to blow up your chances if you might then spend the next two, three years kicking yourself?”

Neat paper on a quantum prisoner's dilemma: https://www.nature.com/articles/srep06286
While the game is derived quantum mechanically and has an entangled strategy, the game itself can be simulated classically with a modified game matrix
In this case the entangled strategy is a cooperator in the limit of no entanglement, otherwise it is essentially a kind of mixed strategy (but not the classical p S_1 + (1-p) S_2 kind)

I've started using https://docs.github.com/en/discussions elsewhere and quite like how it works - especially how it then means issues can be converted to discussions so the remaing issues become an actual todo list. Do we fancy doing that too?
Marc
@marcharper
Willing to try it out :)
vinceknight (he/him)
@vinceknight:matrix.org

Yup me too!
Also, thanks for the pointer to the quantum paper. Looks neat. Will try to read it.
Apologies for the slow reply, have been head under water for a little while (on parental leave, was planning on being more around but 🤷‍♂️.

@marcharper
No worries, hope you are enjoying leave :)

They cite our work:
Of particular interest, the
memory-one PSO Gambler q = [1, 0.522, 0, 0.121], an opti-
mized strategy using particle swarm algorithms in IPD games
with the conventional payoff values [18], belongs to class A
of unbending strategies (Fig. 3a), and WSLS is an unbending
strategy only if T + S < 2P (Fig. 3b).

Just seen this paper mentioned on twitter: https://www.nature.com/articles/s41598-022-11654-2

They fit memory one data to histories of play (similar to our testing ZD paper: https://arxiv.org/abs/1904.00973).

Did they use our library to do it?
vinceknight (he/him)
@vinceknight:matrix.org
[m]
No although, having read only the abstract I think that's understandable.
They have data from actual human interactions and then they measure cooperation rates.
I think it would be neat to add the measure from the testing ZD paper to the library at some point so theoretically someone could look to do it.
to do it* on human interactions.
There's also scope to fit more complex behaviours like the ones we have in the library (the FSMs etc...) to historical data. That would be a neat thing to add to the library.
one day 😆

Oh neat :D
But yeah I agree.
I reached out to them on twitter and their data is available so we could always look at fitting more etc... one day
