How to solve this DE by using  Differential transformation method?

diff(f(x),x\$3)+1/2 * f(x) *diff(f(x),x\$2)=0;

with boundary conditions

f(0)=1 ; f '(0)= lamda * f ''(0)   and   f ' (x) -> 1  as x -> infinity
where lamda is some constant...

How to solve this DE with IC by using DTM.
D^m u(x,t)=u''(x,t)-u^2 (x,t), where n-1< m < n

IC: u(x,0)=1+sin(x), and u'(x,0)=0
