## IAM566 - Numerical Optimization

Credit: 3(3-0); ECTS: 8.0
Instructor(s): Hamdullah Yücel
Prerequisites: Consent of Instructor(s)

#### Course Catalogue Description

Unconstrained Optimization: steepest descent, line search methods, trust-region methods, conjugate gradient methods, Newton and quasi-Newton methods, large-scale unconstrained optimization, least-square problems; Theory of Constrained Optimization; Linear Programming: simplex method, interior point method; Quadratic Programming; Active Set Methods; Interior Point Methods; Penalty, Barrier and Augmented Lagrangian Methods; Sequential Quadratic Programming.

#### Course Objectives

Computational science, engineering and applied mathematics face a growing need to develop algorithms, methods, and simulation codes that solve difficult and large scale problems. Solutions are desired that can provide designs, controls, and inversion results for the best choice of input parameters. Numerical optimization algorithms can provide computer scientist, engineers and mathematicians an avenue to the most desirable solution, automate the execution, and achieve efficient convergence rates.

This course is designed for graduate students majoring in mathematics as well as mathematically inclined graduate engineering students. At the end of this course, the student will:

• learn the central ideas behind algorithms for the numerical solution of differentiable optimization problems by presenting key methods for both unconstrained and constrained optimization, as well as providing theoretical justification as to why they succeed;
• learn the computational tools available to solving optimization problems on computers once a mathematical formulation has been found.

#### Course Learning Outcomes

Upon successful completion of this course, the student will be able to

• recognize the character of an optimization problem (constrained, unconstrained, smooth, nonsmooth) and choose appropriate algorithms for their solutions;
• understand the basic convergence analysis for the learned optimization methods;
• solve optimization problems using Matlab, Phyton, Julia or other commercial software;
• how to use and design efficient numerical optimization algorithms for their own research problems.
