comment Partition of number's squares
The first $n$ I can see this is possible for is $n=8$, and the greedy algorithm from the largest number produces the partitioning. Not sure this will or will not work for $n=1000$

comment The function $f (x) = f \left (\frac x2 \right ) + f \left (\frac x2 + \frac 12\right)$
the only thing i can see is that $$f(x+1)-f(x) = f(x/2+1)-f(x/2)$$ and $f(1/2)=0$
