Process design computations are represented by directed graphs whose edges correspond to streams of information flow between computational units. Algorithm I‐R extends existing algorithms for finding the minimal sized blocks of units between which no recycle exists. Algorithm II‐R orders the sequence of unit computations within a block to minimize the number of recycle parameters. Algorithm III‐R uses the concept of indexing to order computations which evade algorithm II‐R. This work is directed toward the evolution of efficient programs for computer‐aided process design.
