,For A-Level Further Mathematics - Paper 3: Discrete, focus on the following key areas:
1. Graph Theory:
Graphs and Networks: Understand the basics of graphs, vertices, edges, and paths. Learn about
directed and undirected graphs, and apply concepts such as Eulerian paths and Hamiltonian
cycles.
Graph Traversal: Master algorithms for traversing graphs, including depth-first search (DFS) and
breadth-first search (BFS).
Planar Graphs: Study the properties of planar graphs and apply Euler’s formula for planar graphs to
solve problems.
Dijkstra’s Algorithm: Use Dijkstra’s algorithm to find the shortest path between two vertices in a
weighted graph.
2. Algorithms:
Algorithm Design: Understand how to design and analyze algorithms for problems like sorting,
searching, and optimization.
Big O Notation: Know how to express the complexity of algorithms using Big O notation and how to
compare the efficiency of algorithms.
Greedy Algorithms: Study the greedy algorithm approach for optimization problems like the
knapsack problem and Huffman coding.
3. Combinatorics:
Permutations and Combinations: Master the concepts of permutations and combinations, and
apply these to solve problems involving counting arrangements, selections, and distributions.
Binomial Coefficients: Understand the use of binomial coefficients (nCr) and their relationship to
Pascal’s triangle.
Inclusion-Exclusion Principle: Use the inclusion-exclusion principle to solve problems involving
overlapping sets.
4. Recurrence Relations:
Solving Recurrence Relations: Understand how to solve linear recurrence relations (both
homogeneous and non-homogeneous), and use iteration or the characteristic equation method.
Applications of Recurrence Relations: Apply recurrence relations to real-world problems like
population growth, and algorithmic complexities.
5. Binary Relations:
Properties of Binary Relations: Study the properties of binary relations such as reflexivity,
symmetry, transitivity, and antisymmetry. Understand how to determine equivalence relations and
partial orders.
Matrices and Binary Relations: Represent binary relations using adjacency matrices and use these
representations to analyze properties of the relations.
