Hi! You might be interested to know that the CLP procedure implements a bin packing constraint, specifically designed to tackle problems like this one. The constraint programming engine can even be invoked from the OPTMODEL procedure using "solve with clp", but the attached code would need to be translated. I have made the assumption that the optimal solution is attainable. Alternately, one can add an objective function, but that formulation took longer to find an inferior solution. Thanks! Lindsey
