PDF (904K) Actions. Cite ; Favorites ... His colleague Hoffenberg suggested using the simplex method (a standard method of maximizing a linear function of several variables). In 1947, a team took 120-man days to find a solution using the simplex method. A few years later, Dantzig introduced a linear program and started using an IBM 701 computer in the early …
