Course Syllabus
Abstract
This course teaches the basics of computational complexity theory, approximation, and probabilistic algorithms for solving intractable problems including those from data analysis. You will learn:
- definitions of the complexity classes P, NP, and PSPACE,
- techniques to prove that a problem is NP-complete, and
- approaches to solving such problems including exponential algorithms other than exhaustive search, approximation algorithms, and efficient algorithms for special cases.
Learning Objectives
- Be able to recognize whether computational problems are in P, are in NP, are NP-hard, or are PSPACE-hard, by either giving an efficient algorithm or presenting a reduction from a well-known NP-complete or PSPACE-complete problem
- Know various techniques to deal with NP-hard search and optimization problems, both theoretically and at a practical level. We focus on (1) solving hard problems for special inputs, (2) improving exhaustive search, (3) efficiently finding approximate solutions.
- Understand the hardness of several variants of clustering.
- Be aware of other computational complexity classes, relations between these classes, and some open questions in computational complexity.
- Throughout the course, we pay special attention to the Travelling Salesman problem, and the final project asks you to apply the techniques mastered throughout the course to design and implement an algorithm solving this problem in the most efficient way you can think of.
