Data Structures and Algorithms
Run by School of Computer Science and Electronic Engineering
10 Credits or 5 ECTS Credits
Organiser: Dr Ik Soo Lim
Overall aims and purpose
To allow students to use, select, implement and analyse a range of common abstract data types and algorithms.
• Data Types, Abstract Data Types, Theory, implementations and uses of stacks, queues, lists, trees, graphs, hash tables, binary search trees. Constraints and Trade offs (time vs. space).
• Criteria for algorithms. Recursive algorithms: Towers of Hanoi. Data processing algorithms: sorting and searching. Graph theoretic algorithms: traversal, shortest path.
• Efficiency measures for time and space: rates of growth; asymptotic behaviour, big-O notation. Algorithm complexity classes (P, NP, NP-complete).
• New versions of algorithms, moral problems and dilemmas of updating an algorithm, moral responsibility of correctness. And understanding how to result ethical problems of algorithm and data structure development.
Learning outcomes mapped to assessment criteria
Use complexity analysis to assist in the selection and design of algorithms.
|Can rank big-O complexity classes correctly. Can state the complexity of basic algorithms. Can select algorithms appropriately.||Can calculate complexity for simple cases. Understands the nature of NP-complete and computationally impossible problems.||Can calculate complexity for complex cases (divide and conquer).|
Understand the ethical issues of algorithms and the responsibility of the developer.
|Explain areas where moral dilemmas may occur, such as updating an underlying data structure or locating an error in a current algorithm.||Able to discuss various issues and provide realistic solutions and well formed argument.||Able to discuss various ethical issues, where they may occur.|
Show an understanding of the design and implementation of a selection of common algorithms.
|Can select and implement an appropriate algorithm for a problem.||Can describe the basic operation of the given algorithms.||Can design and implement new algorithms based on the given ones.|
Show an understanding of a selection of common Abstract Data Types (ADTs) by appropriate selection and manipulation.

Teaching and Learning Strategy
Interactions via questions-and-answers.
ASSESSED assignments, including tutorial questions, problems, essays etc.
- Numeracy - Proficiency in using numbers at appropriate levels of accuracy
