You are asking whether you can restrict the sum of the weights in every cluster to be less than some constant?&nbsp;&nbsp;</P> <P>&nbsp;</P> <P>If that is the question, then I think the answer is no. The FASTCLUS procedure does not support that option.</P> <P>&nbsp;</P> <P>The question sounds like <A href="https://en.wikipedia.org/wiki/Knapsack_problem" target="_self">the Knapsack Problem in optimization</A>. If so, there are several ways to solve the Knapsack Problem in SAS.</P> Fri, 19 Jun 2020 15:07:46 GMT https://communities.sas.com/t5/Statistical-Procedures/FASTCLUS/m-p/663515#M31622 Rick_SAS 2020-06-19T15:07:46Z
