WebAbstract. Designed in 1947 by G. Dantzig, the Simplex Algorithm was the method of choice used to solve linear programs for decades. Though not a polynomial-time algorithm in the worst case, the Simplex Algorithm is remarkably fast in practice. Problems with thousands of variables and constraints are routinely solved by the Simplex Algorithm.
