ALgorithm Solution

Dear ALL :

I try to set up a simulation coding. THe formula I am with is like

SUMi (SUMj(SUMk(SUM..))) (Ai*Bj*Ck....)

Let n= number of sums.
THe problem is n is not fixed, which is really depend on the input
variable.

Now my question is how to develop such kind of algorithm. I can not
figure it out. Thanks for any comments.
