This course is a prerequisite for Algorithms II, Computer Graphics and Image Processing, Complexity Theory, Artificial Intelligence I.

Aims

The aim of this course is to provide an introduction to computer
algorithms and data structures, with an emphasis on foundational
material. It is suitable for people who did not take discrete
mathematics in Part IA.

Lectures

Discrete Mathematics. Common mathematical notation. Proofs.
Induction. Sets, tuples, functions. Relations and Graphs.
Combinations and permutations. [Ref: Ch 1; App B, C] [3-4
lectures]

Algorithm Fundamentals. Algorithm analysis and design.
Models of a computer; costs. Asymptotic notation. Computational
complexity. Recurrences. Ideas for algorithm design: divide and
conquer, dynamic programming, greedy algorithms and other useful
paradigms. [Ref: Ch 1, 2, 3, 4, 15, 16] [2-3 lectures]

Sorting. Insertion sort. Merge sort. Heapsort. Quicksort.
Other sorting methods. Finding the minimum and maximum. [Ref: Ch 2,
6, 7, 8, 9] [4-5 lectures]

algorithms work, particularly those concerned with sorting and searching

have a good understanding of the fundamental data structures
used in computer science

be able to analyse the space and time efficiency of most
algorithms

be able to design new algorithms or modify existing ones for new
applications and reason about the efficiency of the result

Students are expected to buy and make extensive use of one of the
above references: those not doing so will be severely disadvantaged.
The easiest and recommended choice is Cormen et al. which
covers all the topics in the syllabus: the pointers in the syllabus
are to chapters in that book. The other textbooks are all excellent
alternatives and are sometimes clearer or more detailed than Cormen,
but they are not guaranteed to cover every item in the syllabus. Their
relative merits are discussed in the course handout.
