Synopsis
This unit aims to introduce and develop the theory and applications of combinatorial (counting) methods. Principles of enumeration: elementary counting principles, permutations and combinations, generating functions, recurrence relations, the principle of inclusion-exclusion. Combinatorial structures: block designs, Latin squares, difference sets, directed and undirected graphs, combinatorial matrices, systems of distinct representatives. Applications: design of experiments, error correcting codes, assignment problems, network flows, applications of graph theory. Emphasis is placed on algorithms.
Objectives
On completion of this unit students will have: developed dexterity and skill in the use and choice of counting techniques; achieved a basic understanding of graph theory and in the use of algorithms, both in the proof of graph theory results and in computation; and be able to understand the application of combinatorial methods in the theory of designs and in combinatorial optimisation.
