This algorithm has been implemented in the computer package DICOPT++. Computational experience is presented on a set of 20 test problems. Included are problems for optimum feed tray location and number of plates for distillation columns whose methods are described in detail. The results show that the proposed algorithm can effectively handle design problems."
