Cool, I'll have to look into that in my spare time. Looks a lot more "paper space" efficient and less error prone than what most of us grew up with. On Sat, Nov 3, 2018 at 10:03 AM Tom Johnson wrote: > https://www.facebook.com/637328420/posts/10156877698343421/ >

Don’t know if it is redundant with material somewhere in this post already, but someone I have met who works in this space (mathematics and quantitative social science of gerrymandering) is Wendy K. Tam Cho at UIUC. http://cho.pol.illinois.edu/wendy/ I found

Re: [FRIAM] gerrymandering algorithm question

Hi, everybody. FiveThirtyEight had a five part series on Gerrymandering over the summer which was fascinating. The take-home for me was that the notion – implicit in the gerrymandering conversation – that it would be easy for reasonable people to design fair districts – is insane. In

Re: [FRIAM] gerrymandering algorithm question

Oh, I absolutely agree that we could design districts to maximize any variable we wanted. And with a little luck, we might maximize a couple, or even three. But inevitably, we will encounter some variable that is negatively correlated with those we already maximize, so even we philosopher

Interesting, Tom, What utility do you imagine is being maximized in your plan? N Nicholas S. Thompson Emeritus Professor of Psychology and Biology Clark University http://home.earthlink.net/~nickthompson/naturaldesigns/

Re: [FRIAM] gerrymandering algorithm question

I think you are combining two topics that aren’t related, and I don’t want to play whack-a-mole between them. The first topic is how to perform the multi-objective optimization given quantifiable properties of voters, and how to weight those properties. The second is how (and whether) to

Re: [FRIAM] This is how the Japanese multiply. (Math, not biology)

"Real" and "real math" are two different things. My definition of real math is exposition of the form "definition, theorem, proof". When you figure out what "real" means, let me know. Frank --- Frank Wimberly My memoir:

Re: [FRIAM] gerrymandering algorithm question

First, we would have to agree on whether there will be objectives related to the demography of any district? I prefer only counting the number of current population 18 and over. Or some would argue for the total population of any age. But given either choice, there will be serious suggestions

I have a couple of books on "Vedic Math" - a large set of techniques for how to calculate. This technique was among them. Showed the books to Frank once, he was not impressed, "not real mathematics." davew On Sat, Nov 3, 2018, at 9:02 AM, Tom Johnson wrote: >

Re: [FRIAM] This is how the Japanese multiply. (Math, not biology)

This way of multiplying is isomorphic to what I learned in third grade. Multiply these numbers as you were taught. If your numbers have n and m digits, below the line in the multiplication there will be n m-digit numbers. (Ignoring carries for the sake of exposition), each of those n by m

Re: [FRIAM] This is how the Japanese multiply. (Math, not biology)

Some applied math is real math by my definition as is some CS. Jon, Hywel and I were reading Schutz on general relativity. It was close to being "real math" but I was quite frustrated. He talks a good deal about the metric tensor but never really defines it. As far as I can see it's neither a

Re: [FRIAM] This is how the Japanese multiply. (Math, not biology)

Yeah. I am not on my “Real” kick today. “real” is good enough for me. “real” in the sense of honorable, respectable, normative, proper, honest, genuine, true to itself, etc. But on your definition, applied math wouldn’t be “real”, right? CS wouldn’t be real math, either. To me, math is

Re: [FRIAM] gerrymandering algorithm question

Consider a network where the nodes represent individual membership in a district and the edges connect any two individuals that could possibly be considered as being in the same area. An edge has a weight of -1 if the neighbors are in opposing political parties and 1 if they are the same. A
