### Course Aims

This is a first course in mathematical optimization. It builds the basic knowledge and skills in the theory and techniques of analysing and solving simple optimization models. With these foundations, you will be able to deepen your understanding of more complex optimization models, and their applications to various disciplines in subsequent mathematical optimization and operations research courses.

### Intended Learning Outcomes

Upon successfully completing this course, you should be able to:

1. Solve instances of linear programs with the simplex method.
2. Explain and relate the geometry, the algebra, and the tabular form of the simplex method.
3. Solve instances of minimum-cost flow problems with the network simplex method.
4. Explain the algebra of the network simplex method.
5. Explain the optimality of a solution to a linear program, and the infeasibility of a linear program, using linear programming duality.
6. Conduct sensitivity and post-optimality analysis on linear programs.
7. Solve instances of nonlinear programs via their Karush-Kuhn-Tucker conditions.

### Formative Feedback

1. Online quizzes:
Your performance in an online quiz will be immediately given upon submission of your answers. The feedback includes your performance on each question, possible misconceptions that may lead you to wrong answers, and how the question can be answered.
2. In-class tests:

### Learning and Teaching Approach

 Technology-enhanced Learning (26 hours) The basic theories and solution techniques are explained in the videos. After watching each video segment, you can reflect on its content by completing a short online quiz. Prior to the video sequence, and after the short quiz, you are reminded of the learning outcomes for that LAMS sequence. The online quizzes summarize some of the main learning points into short computational questions. They reinforce your learning as you revisit the online LAMS and classroom activities to formulate solution procedures to these questions. Tutorials (26 hours) You will participate in team-based problem-solving tutorial sessions, where problems are designed based on the theories and solution techniques that you should pick up in the online LAMS sequences prior to the tutorial session. In addition to peer learning through the team-based approach, you will get guidance and one-to-one assistance from the tutor as necessary. Laboratories (8 hours) You will learn how to model real-world optimization problems as linear programs, and solve instances of these models in the lab sessions. The optimization problem will be introduced and the linear programming model explained at the beginning of the lab session. You will then have hands-on experience in extracting the problem data from a randomly selected problem to build a linear programming model, and solve it using a solver of your choice.

### Course Policies and Student Responsibilities

(1) General
You are expected to complete all assigned pre-class LAMS activities, attend all tutorial and lab classes punctually, and complete all scheduled lab assignments, online quizzes, and in-class tests by due dates. You are expected to take responsibility to follow up with course notes, quizzes, lab assignments, and course related announcements for assessments you have missed. You are expected to participate in all tutorial discussions and activities.
(2) Absenteeism
A missed test will be given a mark of zero, unless prior permission is given by the course coordinator, or a leave of absence is approved by the School. If you miss an in-class test, you must inform the course coordinator via email (cbchua@ntu.edu.sg) within 2 working days of the test.
(3) Online Compulsory Lab Assignments and Quizzes
You are required to complete online compulsory lab assignments and quizzes on due dates. You have unlimited attempts. The highest score will be considered in the course assessment.

Good academic work depends on honesty and ethical behaviour. The quality of your work as a student relies on adhering to the principles of academic integrity and to the NTU Honour Code, a set of values shared by the whole university community. Truth, Trust and Justice are at the core of NTU’s shared values.
