Carnegie Mellon University

Algorithms, Combinatorics, and Optimization

Related to the Ph.D. program in operations research, Carnegie Mellon offers an interdisciplinary Ph.D. program in algorithms, combinatorics, and optimization. This program is administered jointly by the Tepper School of Business (operations research group), the Computer Science Department (algorithms group), and the Mathematics Department (discrete mathematics group).

Interdisciplinary Approach

To a great extent, the mathematics used by computer scientists and operations researchers overlap. The boundaries between operations research and computer science have become blurred. Important new theories and whole fields, like polyhedral combinatorics, have been and are being developed jointly by computer scientists, operations researchers, and applied mathematicians (who consider themselves a little bit of both). Presentations of new results on graphs and matroid theory can be heard at operations research conferences, while papers on linear programming, network flows, and matching in graphs are frequently presented at computer science conferences. The mathematical content of the papers has become greater and more diverse. Yet, in spite of this, few Ph.D. students graduate with an equally solid knowledge of all three areas.

The Ph.D. program in algorithms, combinatorics, and optimization is intended to fill this gap. It brings together the study of the mathematical structure of discrete objects and the design and analysis of algorithms in areas such as:

  • Network Optimization
  • Combinatorial Optimization
  • Integer Programming
  • Polyhedral Theory
  • Computational Algebra
  • Convex and Discrete Geometry
  • Number Theory

Course of Study

The coordinating committee has established a challenging core curriculum in analysis, algebra, probability, combinatorics, linear and integer programming, graph theory, convex optimization, algorithms, and complexity theory.
