Overview
Optimization models and software are ubiquitous in industry and academia and arise in a plethora of applications such as engineering design, statistics, and economics. Optimization is used by most Fortune 500 companies, to manage their inventory and workforce, to optimize their cashflow and portfolios, to design efficient supply chains, to manage logistics and transportation, and to train machine learning models.
This course will teach students how to model optimization problems and solve them using modern software. It will teach the fundamentals of algorithms to solve optimization problems as well as the underlying theory and geometry.
Prerequisites
MATH 347 (previously MATH 547) or equivalent.

Coding
We will use Julia (http://julialang.org/) with JuMP (http://www.juliaopt.org/JuMP.jl/0.18/) for implementing optimization models. IJulia notebooks (https://julialang.github.io/IJulia.jl/stable/) will also be used to organize and present our code and its output. A tutorial for installing and using Julia with JuMP will occur early in the semester.
