The Simplex Algorithm Uri Feige November 2011 1 The simplex algorithm The simplex algorithm was designed by Danzig in 1947. This write-up presents the main ideas involved. It is a slight update (mostly in Section 1.9) of lecture notes from 2004. In 2011 the material was covered in much less detail, and this write-up can serve as supple-

Notes on Simplex Algorithm CS 149 Staff October 18, 2007 Until now, we have represented the problems geometrically, and solved by finding a corner and moving around. Now we learn an algorithm to solve this without drawing a graph, and feasible regions. Once we have a standard form of LP, we can construct a simplex tableau, which looks like
