COMPSCI 225 : Discrete Structures in Mathematics and Computer Science
2023 Semester One (1233) (15 POINTS)
On one hand, COMPSCI 225 is an incredibly content-rich course. Our diverse range of topics are listed below. On the other, COMPSCI 225 is best to be thought of not as a smorgasbord of disparate concepts, but rather as a paper centred around one "big" idea: mathematical proof. In mathematics, a proof is an argument we use to show that something is true. In this class, we're going to study what proofs are, and look at how we prove things in the fields of computer science, logic, combinatorics, and graph theory. To do this, our course is going to have a slightly different feel than most other classes you've had - we're going to focus as much on the way arguments are formed as on the solutions to the problems we're studying! This course is suitable for any student who is interested in the foundations of Computer Science, Mathematics, or Logic.
Capabilities Developed in this Course

|Capability 2:||Critical Thinking|
|Capability 3:||Solution Seeking|
|Capability 4:||Communication and Engagement|
- Apply the basic notation and terminology of relations, functions, trees, graphs, and strings. (Capability 1 and 3)
- Translate problems stated in ordinary language (e.g. counting problems or graph problems) into the language of discrete structures. (Capability 1, 2, 3 and 4)
- Apply proof methods (e.g. direct proof, proof by cases) to simple mathematical statements and analyse a simple format of the statements using logic (e.g. propositional logic). (Capability 1, 2, 3 and 4)
- Apply propositional logic to find truth values of statements given in ordinary language. (Capability 1, 2, 3 and 4)
- Apply induction and recursion principles to analysis of algorithms and proving simple mathematical statements (that involve integers). (Capability 1, 2, 3 and 4)
- Display the mastery of basic mathematical results about properties of graphs. (Capability 1 and 3)
- Display mastery of the basics of finite automata (e.g. design automata recognizing the language of strings that contain the substring 'aba'). (Capability 1 and 3)

- 55 points for final exam;
- 15 points for midterm test;
- 30 points for written assignments.
- You must obtain at least 50 of the 100 points available.
- You must also obtain at least 35 of the 70 points available for midterm test + final examination.
This course is a standard 15-point course; as such, students are expected to spend 10 hours per week involved in each 15-point course that they are enrolled in.
For this course, you can expect to spend:
- 3 hours per week at the lectures
- 1-2 hours per week at the drop-in tutoring sections and your lecturer's office hours
- Alongside this, you can expect to spend 1-2 hours per week revising the material from lectures
- 4-5 hours per week working on assignments
Lectures will be available as recordings. Other learning activities (e.g. the drop-in clinics) will not be available as recordings. The activities for the course are scheduled as a standard weekly timetable.
The assignments can be completed online. The mid-semester assessment and exam will follow the current University of Auckland test and exam policies.
This course may be taken remotely if you meet Ministry of Health guidelines and receive an exemption or cannot attend because of border restrictions.
Course materials are made available in a learning and collaboration tool called Canvas which also includes reading lists and lecture recordings (where available).
Please remember that the recording of any class on a personal device requires the permission of the instructor.
- A coursebook containing the lecture notes will be available from Canvas
During the course Class Representatives in each class can take feedback to the staff responsible for the course and staff-student consultative committees.
At the end of the course students will be invited to give feedback on the course and teaching through a tool called SET or Qualtrics. The lecturers and course co-ordinators will consider all feedback.
Your feedback helps to improve the course and its delivery for all students.
Feedback suggested we give students more problems to practice. We will do that during the coming semesters
The University of Auckland will not tolerate cheating, or assisting others to cheat, and views cheating in coursework as a serious academic offence. The work that a student submits for grading must be the student's own work, reflecting their learning. Where work from other sources is used, it must be properly acknowledged and referenced. This requirement also applies to sources on the internet. A student's assessed work may be reviewed against online source material using computerised detection mechanisms.
- You must write up your work separately, write up solutions in your own words, and only write up solutions you understand fully.
- When writing up your own work, you can directly cite and use without proof anything proven in class or in the class notes posted online. For anything else - i.e., results from textbooks, Wikipedia, etc. - you need to both cite in your write-up, and reprove the results you're using from those sources carefully in your own words. Simply copying solutions over directly is plagiarism/cheating/otherwise poor academic form; it is passing off the ideas of others as your own work (which is bad!)
- With that said: you are certainly welcome (indeed, encouraged) to read and learn what other people have thought about the concepts that we're covering in this class! All I am asking you to do here is to not claim the ideas of others as your own work and to rephrase and present any such ideas you encounter in a new way so that it is clear that you have actually learned something.
Class representatives are students tasked with representing student issues to departments, faculties, and the wider university. If you have a complaint about this course, please contact your class rep who will know how to raise it in the right channels. See your departmental noticeboard for contact details for your class reps.

If your ability to complete assessed coursework is affected by illness or other personal circumstances outside of your control, contact a member of teaching staff as soon as possible before the assessment is due.
If your personal circumstances significantly affect your performance, or preparation, for an exam or eligible written test, refer to the University’s aegrotat or compassionate consideration page https://www.auckland.ac.nz/en/students/academic-information/exams-and-final-results/during-exams/aegrotat-and-compassionate-consideration.html.
This should be done as soon as possible and no later than seven days after the affected test or exam date.
In the event of an unexpected disruption, we undertake to maintain the continuity and standard of teaching and learning in all your courses throughout the year. If there are unexpected disruptions the University has contingency plans to ensure that access to your course continues and course assessment continues to meet the principles of the University’s assessment policy. Some adjustments may need to be made in emergencies. You will be kept fully informed by your course co-ordinator/director, and if disruption occurs you should refer to the university website for information about how to proceed.
The delivery mode may change depending on COVID restrictions. Any changes will be communicated through Canvas.
