Lectures, Tutorials, Helpdesks• Lectures: Tuesday 12:00-12:50, MCLT103• Lectures: Thursday 12:00-12:50, SUMT228• Lectures/Tutorials/No lecture: Friday 12:00-12:50, SUMT228
• Tutorials– Start from week 2– 10 slots, see timetable in the course homepage– Signup through MyAllocator
https://www.victoria.ac.nz/students/study/timetables/tutorial-sign-up– Small groups (30~40), go through (tough parts of) the lecture content– Lectures cannot cover every single detail– Tutorials can be very helpful
4
Lectures, Tutorials, Helpdesks• Helpdesks:
– From Week 2– CO 242b– 13:00-14:00 Monday to Friday– 13:00-15:00 (2 hours) for the weeks when the assignments are
due.• Helpdesks tutors are on the course homepage.• First week: no helpdesks, but will be a tutorial in lecture slot• No scheduled labs
5
Course Objectives• Select, adapt, and implement a wide range of standard
algorithms and data structures to construct software solutions to complex problems
• Understand algorithms described in pseudocode and to use analysis of an algorithm's time and space requirements to determine applicability to a problem
• Recognise the distinction between "easy" problems, 'hard' (NP) problems, and uncomputable problems and the consequences for constructing algorithms and programs for such problems
• Know and be able to implement important algorithms related to graphs, searching, parsing, basic graphics rendering, and B-Trees
6
Course Materials• No compulsory “text book”, but below will be useful
– Book: “Algorithms and Data Structures” – a selection of chapters from various textbooks compiled by Alex Potanin, Pearson(some copies may be around, especially second hand, borrow from library)
– Wikipedia pages: extremely good resource on algorithms.– Lecture notes on the course website:
https://ecs.victoria.ac.nz/Courses/COMP261_2020T1/
• Tutorials and helpdesks will be very helpful
7
Assessments• Tests (20%) and Final exam (50%)
– Mid-term test: 6-7pm (45 mins), 30 Apr (Thur)– Exam: exam period
• Assignments (30%)– 5 assignments, roughly every 2-3 weeks– 6% each– Deadlines:
• Due at 23:59 Sundays• 20 marks off for first 24 hours late, 40 marks off for next 24 hours,
0 marks more than 2 days late. • 3 "late days" for the whole course, so use wisely• Further extensions is only allowed under special circumstances (having
other assignments due at the same time is not special)• IN PERSON MARKING!!! 10%-100% PENTALTY IF YOU MISS IT!
8
Assignments• Assig 1: Graph basics• Assig 2: Pathfinding and articulation points• Assig 3: Fast Fourier Transform• Assig 4: Parsing • Assig 5: Indexing, B+ trees, low-level file structures
• Submissions– Code + report (Submit through the system)– Signup a 15-minute session for marking, demonstrate program and
explain key details to the marker (tutor)– Marked in the two weeks after the due date (e.g. week 5-6 for A1)
9
Workload• 10 hours per week
– Lectures and tutorials: 3 hours– Review and reading: 2 hour– Assignment: 5 hours
• Assumptions:– COMP103: collections, complexity (Big-O), searching and sorting– Math161/ENGR123– Ability to find things out by yourself (COMP261 is not spoon-feed)
• Start the assignment as early as possible!!!
10
Rules and Policies• Plagiarism is NOT tolerated
– Submit someone else’s work as your own, including• material from a published source such as a library book, a journal article,
etc.• material from an on-line software library, web pages, etc.• the work of another student, friend, relative, etc.
• Penalties: – zero marks for the work to which it relates– greater penalties in accordance with the University's Statute on
Student Conduct
• If you discussed with other students, state it clearly in the report to avoid plagiarism issue

A word from recent Vic Uni grad, now Software Developer-Leyton…
21
Thank you for your time!
Graph• Many real-world applications
– places with connectionsairports & flights,intersections & roads,network switches and cables ….
– entities with relationshipssocial networks,biological modelsweb pages ….
– states and actionsgames, plans, …..
22
Graph• A collection of nodes• A collection of edges (directed and undirected)
– We only consider directed edges– Undirected edge can be seen as a pair of directed edges– (A, B) can be seen as (A -> B) and (B -> A)
• Relationship between nodes and edges– Nodes form edges– Edges connect nodes
• Other properties in graph– Multi-graph: multiple edges between the same pair of nodes– Loops
• Other complex properties– No turn right/left
