Conic Linear Programming

by

C. Helmberg, TU Chemnitz

Standard linear programming may be thought of as optimizing a linear cost function over the intersection of an affine subspace and the cone of nonnegative vectors. In conic linear programming the cone of nonnegative vectors may be replaced by various other closed convex cones, like the second order cone (in it, the first coordinate bounds the norm of the vector of the remaining coordinates) or the cone of (symmetric) positive semidefinite matrices. For the latter two examples there also exist rather robust algorithmic methods to solve these optimization problems efficiently and this opens up a whole new world of important applications. The course offers a brief introduction to theory, algorithms and applications of conic linear programming. The following two papers would each be suitable for a group of 3-4 students to read and prepare a presentation on (please try to understand and explain the applications, not the theory and algorithms):
