We don't know how the variables are interrelated. The only thing we can tell is that you will have to use "ga" to solve your problem.

Hi Imad,

F = symsum(f,k,a,b)

returns the sum of the series f with respect to the summation index k from the lower bound a to the upper bound b. You can use this to find the summation of variables in the given equation. Yopu can use the below link for more information.

Sum of series - MATLAB symsum - MathWorks India

Since one of the variables require multiple summations, you can use nested sum or symsum to get the desired output. Refer this link for more information: Multiple Summation in matlab - MATLAB Answers - MATLAB Central (mathworks.com)

You can use the min function to then compute the required answer.

Hope this solves your issue.
