<p>Much of the recent work on the automated design of VLSI chips has concentrated on routing problems associated with such designs. One major class of routing problems focuses on single-row routing. Recently, the traditional single-row routing model has been generalized to allow external wires. Under this generalized model, it is possible to route many more single-row routing instances than in the traditional model. There is, however, a clear disadvantage in the use of external wires, since they force a lengthening of the channels surrounding the single row of terminals. Thus, it is desirable for these generalized single-row routings to use a minimum number of external wires. A linear-time algorithm for determining the minimum number of external wires needed to route a given instance of single-row routing is provided here.</p>
