Thread: Minimize an Error Function

Hi,
How can I find x1...xL such that minimize the Sigma expression having the following assumptions (see attached file)?
S1...SK and c1...cK are given constants (belong to R).
thanks for your assistance.

You only need minimise:

- sum_{i=1 to K} [c_i (x_{A_i} - x_{B_i})^2]

or maximise:

sum_{i=1 to K} [c_i (x_{A_i} - x_{B_i})^2]

Which needs all the c_i be negative.

sorry but the attached image is actually the correct minimization experssion.
Appreciate your help.
