Optimization problems appear in many reallife situations, such as production processes, industrial design, logistics and machine learning. This course aims to expand on algorithmic principles and fundamental ideas of linear optimization and give an introduction to techniques for nonlinear optimization. The course enables the student to follow more advanced courses in continuous and discrete optimization.
The course treats optimization of a function mainly in two different settings: 1) when the function is linear under linear (in)equality constraints, and 2) when the function is nonlinear with no constraints. The first setting expands on the assumed prior knowledge with more algorithmic methods and proofs of theorems like Farkasâ€™ lemma. We show that these results directly imply Strong duality of linear programs and we expand the concept of complementary slackness with approximate complementary slackness. We then study the properties of convex sets and convex functions, which play an important role in optimization and applied analysis. Finally, we treat nonlinear, but also unconstrained, optimization, using concepts like descent methods, line search and Newton methods.
