What the fuck is that
ELI5:
Imagine some sort of a polynomial function
f(x) = r * x * (1-x)
that is also depending on some constantr
in range0 < r < 1
.You apply
x = f(x)
for many times, at your wish. Think of it as a for-loop, or f(f(f(...f(f(x))...))). The resulting value will reside (converge) to some value.So, this looped function sets to some stable point with any
r
in range untilx < 3
. After that, it doesn't converge but it will constantly jump between one of 2 points, then 4, 8, ... and at some point it goes wacky-macky.The graph from Wikipedia merely shows the probability of the value
f(f(f(...f(f(x))...)))
for allr
in the given range.If you're curious, Veritasium's made a good explanation here: https://youtu.be/ovJcsL7vyrk
