thanks a lot for your support

but the problem is that sometimes sum of c's can be equal to 6, 5, 4, 3, 2 OR 1

the sum of c's should take a value that gives the best optimization solution

so now I will be having a big big big bundle of permutations, so are there any new options???????

sorry for the disturbance and thanks for the support !!!!!
