Module Learning Outcomes

On successful completion of this module, students will be able to:

  1. Have gained significant knowledge on algorithms and data structures, and the mathematical theory and techniques to evaluate their efficiency and effectiveness;
  2. Have the ability to evaluate algorithms in terms of their running time and memory space requirements and classify those algorithms in the major complexity classes using appropriate performance models;
  3. Be able to efficiently implement the operations of the main data structures used in most programming;
  4. Have gained experience through experiments in implementing effective new and existing algorithms;
  5. Be able to identify the most suitable data structures and algorithms for each programming problem based on the parameters of the problem, the advantages and limitations of each data structure and algorithm, the resources available, the desired performance criteria etc.;
  6. Be able to design and implement robust, effective and well-structured Java programs using industry standards such as Abstract Data Types and the approaches of unit testing and test coverage.

Recommended Reading List

Module Pre-requisites

Prerequisite modules: N/A

Other/alternative non-module prerequisites:

The module assumes students have previous knowledge of standard programming in Java. This includes Java syntax including data types, commands, loops, conditionals and other common programming structures, and the Java Object-Oriented model including classes, fields, methods, inheritance and interfaces. Students with working knowledge of another programming language such as C/C++ should be able to acquire the required knowledge in Java from online tutorials.
