Content: Many complex everyday problems involve finding an optimal solution in a large, but finite, solution space. Combinatorial optimisation is concerned with the study of effective algorithms for solving such problems by cleverly exploring the solution space. Although many practical problems appear to be insurmountably hard (NP-complete), there are a vast number of problems that can be solved by effective (polynomial time) algorithms.

This module provides an introduction to combinatorial optimisation. In particular, we discuss various fundamental graph-theoretic algorithms. Among others we aim to cover, shortest path algorithms, minimum spanning trees, matching, coverings, network flows, cliques and colorings.

At the end of the course you are expected to have good understanding of various fundamental graph theoretic notions and algorithms. You should also appreciate constructive proofs in finite mathematics.
