To make best use of available learning time by encouraging active learning and by transmitting information in the most effective ways.
To make students aware of the importance of algorithmic concerns in real-life Computer Science situations.
To emphasise practical concerns, rather than mathematical analysis.
To become confident with a range of data structures and algorithms and able to apply them in realistic tasks.
- ILO 1 Analyse problems to identify and implement the most appropriate algorithmic solution
- ILO 2 Define standard notions of asymptotic complexity and use these to reason about the complexity of algorithms
- ILO 3 Use pseudocode to represent algorithms and informally reason about their correctness
- ILO 4 Recall the definitions and representations of basic data structures and the complexity of the operations on them
- ILO 5 Explain, using examples of real-world applications, standard algorithmic problems coming from sorting and searching on different data structures, operations on graphs, and number theory
- ILO 6 Identify from a set of taught algorithms, which algorithm should apply in a given situation, explain how it should be applied, and compare the solution to possible alternatives
- ILO 7 Explain the algorithmic techniques such as divide-and-conquer, dynamic programming, greedy algorithms, and linear programming, discuss when they are appropriate, and apply them to solve problems
- ILO 8 Recall and explain the notions of tractability and NP-completeness, with a particular focus on classical NP-complete problems, and apply these to demonstrate NP-completeness of new problems
Algorithms - what they are and how to express them (in pseudocode and selected programming languages: Java, C or Python).
Practical experience in devising, assessing and using algorithms:
- considerable practice in algorithmic problem solving for realistic problems
- examples from a wide range of application areas
- finding appropriate algorithms and data-structures
- inventing appropriate algorithms and data-structures
Practical experience in 'algorithmic literacy' - knowing how to use the extensive literature on the subject, recognising what algorithms to use in applications and assessing their utility.
A range of basic data structures: arrays, lists, trees (including ordered and balanced trees and heaps), and various kinds of graphs. Representations of basic data structures in programming languages.
A range of basic algorithms: searching and sorting algorithms, tree traversal and manipulation algorithms, some basic graph algorithms. Other algorithmic areas will be explored through practical examples.
An introduction to algorithmic performance: space and time requirements, worst-case, average-case and best case estimates. Practical experience and techniques for measuring and predicting performance: Counting operations.
Scaling and some common rates of growth.
Reasoning about algorithms - experience in informally reasoning about algorithms to establish correctness.
