Description

This subject covers the theory and practice of numerical methods in modern mathematical computing. The subject addresses the main numerical techniques in calculus, minimisation and optimisation, numerical integration and Monte Carlo methods, the numerical solution of large linear systems, and the numerical solution to ordinary and partial differential equations. Students learn the theoretical underpinnings of these algorithms, with a focus given throughout the subject on practical implementation and coding. The Python programming language is used throughout the subject.

Subject learning objectives (SLOs)

Upon successful completion of this subject students should be able to:

1. Describe the main algorithms for solving a range of important mathematical problems.
2. Design and implement code to solve a range of problems numerically.
3. Explain why various numerical algorithms work, and what their limitations are.

Course intended learning outcomes (CILOs)

This subject also contributes specifically to the development of following course intended learning outcomes:

  • Demonstrate theoretical and technical knowledge of mathematical sciences including calculus, discrete mathematics, linear algebra, probability, statistics and quantitative management. (1.1)
  • Evaluate mathematical and statistical approaches to problem solving, analysis, application, and critical thinking to make mathematical arguments, and conduct experiments based on analytical, numerical, statistical, algorithms to solve new problems. (2.1)
  • Work autonomously or in teams to demonstrate professional and responsible analysis of real-life problems that require application of mathematics and statistics. (3.1)
  • Design creative solutions to contemporary mathematical sciences-related issues by incorporating innovative methods, reflective practices and self-directed learning. (4.1)
  • Use succinct and accurate presentation of reasoning and conclusions to communicate mathematical solutions, and their implications, to a variety of audiences, using a variety of approaches. (5.1)

Contribution to the development of graduate attributes

GA1: Disciplinary knowledge

This will be achieved through the analysis of the effectiveness of various numerical methods, and through the writing of the appropriate code for the solution of problems to a specified accuracy.


GA2: Research, Inquiry and Critical Thinking

The check-in Assignments will require the students to synthesize solutions to unseen problems. They will also be required to analyse the accuracy of their own solutions.


GA3: Professional, Ethical and Social Responsibilty

Students will be expected to apply high-level professional conduct and responsibility in the performance of their own work throughout the semester and especially in the computer labs.


GA4: Reflection, Innovation and Critical Thinking

The final project will require the students to apply solutions learned throughout the semester to an original and authentic problem. They will also be required to analyse the performance of their project code, as well as critically assess code for structure and accuracy.


GA5: Communication

Students will present their final project in the form of an oral report, which must clearly outline their problem, how this was approached and how their code works.

Teaching and learning strategies

Subject content will be presented in a combination of online materials and in the workshops.

Workshops will take the form of an interactive session (2 hours per week) where the material is covered in depth.

Students are expected to revise the online material before each workshop.

Computer labs (2 hours per week) will focus on the practical implementation of numerical methods.

Direct feedback will be provided during the computer labs. Further feedback on progress will be provided using the check-in Assignments which are spaced throughout the semester.

Students will be encouraged to develop code-sharing practices in the computer labs, and to tackle problems collaboratively, as well as being able to work on solving problems individually. A central aim of this is to prepare students for real-world coding environments, which consist of a mix of collaboration with intense periods of individual work.

The final project will enable the students to tackle an authentic and challenging problem in science or mathematics that can be approached using the methods given in this subject.
