The Simplex Form • We have seen that different forms of linear programs are “equivalent”: – Standard Form – Canonical Form – LPs that contain unbounded variables • We consider exclusively LPs in Standard Form for which we sketch an algorithm in the following. – Min cTx – Ax = b – x ≥0

The Simplex algorithm aims to solve a linear program - optimising a linear function subject to linear constraints. As such it is useful for a very wide range of applications.

In most cases, only worst-case instances are considered. Often, this is not very representative for the real behaviour of the algorithm. Prominent examples include Quicksort and Simplex algorithm. COMPUTATIONAL COMPLEXITY OF THE SIMPLEX ALGORITHM KARMARKAR’S PROJECTIVE ALGORITHM We are only required to determine a function g (m;n;L) in terms of (m;n;L) such that for some su ciently large constant ˝>0, we have f (n;m;L) ˝g (m;n;L). i.e., O(g (m;n;L)). Example: For algorithm actually involving a maximum of f (n;m) = 6m2n + 15mn + 12m is O m2;n.

The simplex algorithm proceeds by performing successive pivot operations each of which give an improved basic feasible solution; the choice of pivot component at each step is largely determined by the requirement that this pivot improves the solution. let a linear plan be given by a canonical tableau. Introduction • Simplex method which was developed by George B. DANTZIG (1914-2005) in 1947.

However, in a landmark paper using a smoothed analysis, Spielman and Teng (2001) proved that when the inputs to the algorithm are slightly randomly perturbed, the expected running time of the simplex algorithm is polynomial for any inputs -- this basically says that for any problem there is a "nearby" one that the simplex method will efficiently solve, and it pretty much covers every real-world linear program you'd like to solve.
