### Module summary

Discrete mathematics is the area of mathematics concerned with the study of discrete (i.e. distinct, separate, unconnected) objects. The typical problems studied in discrete mathematics involve counting the elements of a finite set (e.g. how many ways are there of choosing a 4-digit PIN number?), studying graphs (e.g. can we check that two computers in a network are connected), and finding algorithms to solve problems (e.g. is there an algorithm that checks if a number is prime). Correspondingly, the module will introduce key ideas from Combinatorics, Graph Theory and Computability Theory.### Objectives

To introduce students to combinatorial thinking, and to demonstrate the wide range of applications.On completion of this module, students should be able to:

a) solve counting problems involving permutations, combinations and the Inclusion-Exclusion principle;

b) solve linear difference equations, formulate counting problems as linear difference equations and know some applications;

c) test a graph to determine whether it is connected;

d) use Kruskal's algorithm to find minimal connectors;

e) in simple cases, determine whether or not a graph is planar;

f) prove and apply Euler's formula for planar graphs;

g) devise register machines programs for simple functions;

h) in simple cases, prove that a function is recursive;

i) prove that the Halting Problem is undecidable.

### Syllabus
