@JB King good point, sometimes strange things happen aroud the zero :)

yes, but what about closed form solution ? it seems to have something to do with n(n+1) sum ?

comment Checking Sudoku - sufficient sums
ok I have not answer but information that make my question invalide math.stackexchange.com/questions/157682/… my condition could be substituted by taking sums of 2^value, but I'm not sure on 100%

I've wrote that.

but what about $\delta^{bis}_{2}:=E(\big|-|X-E(X)|-\delta_1\big|)$ it's the symmetric part of the situation?

comment Minimize combined variance of multiple measurements with known (but varying) variance
"The measurements are of course correlated (as they measure the same property)! And I can also calculate a covariance matrix..." but do you suppose that errors of measurements are also correlated ?

comment What is closed-form expression for $F(n)$ when $F(n)=F(n-1)+F(n-2)$ and $F(0)=a$,$F(1)=b$ and $a,b>0$?
as I thought, but is there way to effectively search for them ?

comment What is closed-form expression for $F(n)$ when $F(n)=F(n-1)+F(n-2)$ and $F(0)=a$,$F(1)=b$ and $a,b>0$?
How to find a and b, if I have only given value of F(n) (without knowledge of n) ?

great, I have value of $F(n)$ and have to find smallest $a,b>0$ your answer is going to be very helpful
