The Conway sequence
a(n)
is defined by
a(n)=a(a(n-1))+a(n-a(n-1))
, where
a(1)=a(2)=1
. In this Demonstration you can vary the initial conditions, but the sequence may be undefined for some values of
n
. A wide variety of behaviors is observed, including variations of the Blancmange function. A call graph is also shown.
