BFACF Demos Help

Simulation method: 
You have the choice of two (soon three) simulation methods, BFACF and KJC (kink jump crankshaft).
BFACF is ergodic and KJC isn't. However, KJC is length preserving and "ergodic enough" for some us,
at least for long, loose knots. If you are using the KJC method, the z and p() sliders have no 
meaning.

Plot:
Simulation needs to be running to see the plot update. If the plot is inappropriately scaled, try
changing the scale with a command something like:
plot scale 1.08
plot scale 3
(default is a scale of 1)

set probs:
These are convenience buttons to automatically set the probabilities. The "from z" button sets the 
probabilities according to the standard formula. "0 only" is equivalent to the KnotPlot command
bfacf prob 0 1 0
and reduce equivalent to
bfacf prob 0 1 1

p(+2) p(0) p(-2) sliders:
Set the probabilities for the different BFACF moves for your own crazy interests.  Useful for the
minimal stick search, or to get very long knots. 

z sliders:
First slider goes from z=0 to z=0.208 (the critical value), giving you finer control over this
range. The other slider is from z=0 to z=1.  Changing these slider values will automatically set
the probabilities according to the formula.  To set a specific value for z, either use type it into
the KnotPlot Command Window, for example:
bfacf z .108
or double click on the value field in the slider.
