Solved: FASTCLUS

Can I put a upper bound on aggregate weights in a cluster using fastclus ?

I am going to guess that you are using a WEIGHT variable. You are asking whether you can restrict the sum of the weights in every cluster to be less than some constant?

If that is the question, then I think the answer is no. The FASTCLUS procedure does not support that option.

The question sounds like the Knapsack Problem in optimization. If so, there are several ways to solve the Knapsack Problem in SAS.
