Thank you.
I have, since about 1961, dealt with computer languages from MAD
(Michigan Algorithmic Decoder) through Fortran, early Basic, turbo
Basic, Pascal, C++ and APL*Plus then J . The earlier languages were
compiled and the compilers used "assembly" code. C and its relatives,
as far as
Oops, I did not think about that "reflexive giving" wart.
Here's a fix for my version:
tick=: (0 >. <:) + i.@# +/@:(=/)~ I.@:* (] + <:) +/@:* ?@# <:@#
require 'stats'
stddev"1 tick^:(i.10) 45#45
0 0.977008 1.18705 1.73205 2.01133 2.15322 2.46798 2.86832 2.97719 3.1334
tick^:1]20#2
The number of $ available each round is the number of people with >&0. The
number of potential recipients is the population. This simplification though
means its possible for someone to pay himself.
A correction to your version,
/:~@(-&1`]@.(=&0)"0 (#/.~@] + ~.@]{[)`(~.@])`[} >&0 # (?@#~@#
His narration states
Quote: “Imagine a room full of 100 people with 100 dollars each. With every
tick of the clock, every person with money gives a dollar to one randomly
chosen other person. After some time progresses, how will the money be
distributed?”
And I came up with this simulation. (45 p
Why do you think that?
Or were you referring to Xiao-Yong Jin's narrative?
Thanks,

You may also be interested in this, a purely J implementation of the
Levenberg-Marquardt nonlinear least-squares optimization:

So, you start with $10,000 (=100*$100) but end up with $2,025 (=45*$45),
how?

I don't really understand what you mean by "mean expectations" - could
you describe the intent there?
That said, here's how far I've gotten in implementing this concept:
tick=: (0 >. <:) + i.@# +/@:(=/)~ +/@:* ?@# #
(mean,stddev)"1 tick^:(i.10)]100#100
1000
100 0.932034
100 1.41421
I thought this is a good lunch break exercise.

Thanks, Devon.
Actually I've come across a few over the years. But their authors don't go
noising them about. :-)

BTY - I think it's really cool there's a Mac app using J but I don't really
work in that space myself.
