Two general types seem to exist:
1) a(n)=a(n-a(n-1))+a(Floor[a0*n/b0]): a0<b0 ( noise-like)
2) a(n)=a(Floor[a0*n/b0])+a(Floor[c0*n/b0]): c0<a0<b0 ( step-like)
FORMULA
a(n)=a(n-a(n-1))+a(Floor[a0*n/b0]): a0<b0:a0=1;b0=8
MATHEMATICA
a[0] = 1; a[1] = 0; a[2] = 1; a[n_] := a[n] = a[n - a[n - 1]] + a[Floor[n/8]] b = Table[a[n], {n, 0, 200}]
