Combinatorial problems arise in many areas of computer science, engineering and mathematics. Combinatorial structures such as graphs and set systems are used to model many problems in computing.
In this course, we will study combinatorial algorithms to solve the following types of problem: 
  • Generation: construct all combinatorial structures of a particular type.
  • Enumeration: compute the number of different combinatorial structures of a particular type.
  • Search: find at least one example of a structure of a particular type.

  • In the first part of the course, students will learn a wide range of techniques to solve these problems. In the second part, they will learn more advanced techniques as well as work on a project related to their research interests. 
    1. Basic algorithms for ordering, ranking and unranking of basic combinatorial objects. -- Chapters 2 and 3
    2. Exhaustive search and exhaustive generation algorithms (backtracking, branch-and bound). -- Chapter 4
