Hi, Namir|

5:30 am here so just a couple quick observations:

(07-12-2018 11:15 PM)Namir Wrote:  F(X,a) = (LHS1 - RHS1)^2 + (LHS2 - RHS2)^2 + ... + (LHSn - RHSn)^2

Where:

LHS1 = sum(X(i)) for i = 1 to n
RHS1 = - a(n-1)/a(n)
....
LHSn = product(X(i)) for i = 1 to n
RHSn = (-1)^2 * a(0)/a(n)

1) without loss of generality you can consider a(n) to be 1. If it's not, simply divide all other coefficients by it before doing anything else.

2) there's a typo in your RHSn, (-1)^2 is obviously wrong.

Regards.
