Balloting
Iteration of a balloting paradigm, using random number generator.
Very surprising patterns amdist chaos. It is very different from
a coin toss paradigm, in that the voting population decreases as
the balloting progresses. That is a very important distinction,
as this algorithm was designed to determine the margin of error
in the predicted outcome.
I developed this algorithm in November 2000 as part of a DOS program
I wrote to simulate the Florida presidential balloting, in order to
predict who would win the recount - Bush or Gore. The program
predicted that if a standard for counting ballots was adopted
that accounted for the difference in undercount between "Marksense"
counties and "Optical" counties, then Gore would have an 80 percent
chance of winning, with the most likely margin of victory being
approximately 350 votes. One year later, such a recount was
performed, and Gore actually won by about 350 votes, using
the standard whereby "dimples" counted as votes. It was the
only standard that ever made any sense. Dimples don't appear
without the voter taking some action, as emphasized by the
president of the company that manufactured the Marksense machines,
and as verified by their own testing. In fact, all other standards
for interpreting ballots produced results that fantastically failed
to account for the difference in undervote between Marksense
counties and Optical counties.
Anyhow....
Even though my program incorporated the BASIC random number
generator, distinct patterns always appeared in the graphical
output. This is an example of applying an algorithm to
randomness. Without the algorithm, no number of iterations
of XY plots, with Y being assigned randomly, will produce
any pattern.
The pattern that is generated matches that which is generated
by two other very different algorithms. One of those is the
logistic map, and the other is a repeating line drawing routine
used to color a plane in a CAD program. Both of those are shown
on other pages of this website.
(VisualBASIC and DOS BASIC program code displayed further down on page)
The following graphs were generated using a slightly modified
version of the DOS program using VisualBASIC:
|
Output: First 20 percent
Amplitude: .5
X increment: .04
Votes: 20000
Trials: 500
Output: First 50 percent
Amplitude: .5
X increment: .04
Votes: 20000
Trials: 500
Output: First 80 percent
Amplitude: .5
X increment: .04
Votes: 20000
Trials: 500
More amazement: When I shrunk the images, even more
accentuated and previously undetected patterns appeared.
The greater the shrinkage, the more revealing are the
newly seen patterns. The following three images are
1/2 size, 1/4 size and 1/6 size (then re-enlarged) of
the "50 percent" image:
Output: First 50 percent
Amplitude: .5
X increment: .04
Votes: 20000
Trials: 500
Strangely enough, I discovered this identical pattern
when I graphed the logistic difference equation in a
circular manner for a given value of the parameter r.
Those images are displayed on the logistic difference
equation page of this website.
Just as surprising, this very same pattern showed up on
one of my 3D-CAD images, due to some odd combination of
perspective angle and the ratio of cross-hatch lines used
to color a plane. I've never seen that pattern or any
other pattern appearing on any of my thousands of CAD
images. Here it is:
Here is an image from my original DOS BASIC program, which
I used to determine the margin of error in my prediction:
By varying the scale and the percent of output, one can
adjust the manner in which the patterns appear:
Shrinking the above image gradually revealed some
grouping of the Y values. See next two images:
Here is my original code for the VisualBASIC version.
It's been 16 years since I wrote this code,
and I have to admit - it somewhat baffles me.
"G" in the code stands for "Gore".
Private Sub voterunbtn_Click()
Set viewport.Picture = LoadPicture("")
DONE$ = "done"
per = Val(perbox.Text)
amp = Val(ampbox.Text)
inc = Val(incbox.Text)
iter = Val(iterbox.Text)
trials = Val(trialsbox.Text)
iterper = Int(iter * (per / 100))
For total = 1 To trials
Randomize Timer
X = 0: G = 0: A = 0
For C = 1 To iterper
RN = Rnd(1)
If RN >= 0.5 Then G = G + 1
A = A + 1
A2 = A / 2
Y = (A2 - G) * (iter / A)
X = X + ((100 * inc) / per)
viewport.PSet (X, Y / amp), RGB(0, 0, 0)
Next C
Next total
finalnum.Text = DONE$
End Sub
