COWLES FOUNDATION DISCUSSION PAPER NO. 649 "Scarf's Procedure for Integer Programming and a Dual Simplex Algorithm" Philip M. White, Andrew S. Caplin and Ludo Van der Heyden November 1982 Herbert Scarf has recently introduced an algorithm for integer programs based on the concept of primitive sets. We show that as the choice variables become continuous, this algorithm converges to a dual simplex algorithm. This result is robust in the sense that even before the limit is reached, the simplex path is contained in the primitive sets which define Scarfs path to the solution of the integer program.
