Here you go! This lecture (phrased to hopefully be useful to people even outside of the class I'm teaching) goes over the 5–6 GA hyperparameters and hwo they fit on the diagram above.

Oh -- a key to the quantities:

M: Census population size (N for popgen)
R: Size of parent pool (effective pop size N_E for popgen)
Pc: Crossover fraction
Pm: Mutation rate
E: Number of elites carried over
SP: Selection pressure in selection operator

/cc: @wcratcliff.bsky.social -- You might have some passing interest in this. An attempt to more seriously use concepts from popgen and artificial selection to better understand and use evolutionary algorithms, and I would argue the hand-drawn diagram applies to artificial sel'n in general.

I follow that up with this slide, which I put together a while back to help students use ideas from popgen to build high-level intuition about what you're trying to do when changing hyperparameters/designing new operators. The new diagram just makes that more explicit and tailored for a GA.

Well, the ACM Digital Library Premium is pretty slimy too -- doubling the membership fee just to get access to articles in order to support "Open" access elsewhere -- but at least ACM is much cheaper than IEEE and even gives you an IEEE discount.

After trying out Plus for a few days, the on-screen UI downgrade was just too bad. The voice assistant is a bit better, but it's not worth the losses. Fortunately going back to the old version is as easy as:

"Alexa, end early access"

Hopefully they keep working on this product.

I see! I don't think they're telling the whole story about what happened, but I'm glad they got it fixed!

The fix is out – see link below. I don't think their explanation tells the whole story (otherwise, why would installing an older version fix the issue as well as it did?).

Download the fixed version manually (affected computers must have this done manually) from:
