Assignment 1 - Weighted Graphs
Your task is to implement a weighted graph class, offering a reasonably effective suite of operations, including computing the minimum spanning tree, depth and breadth first traversals, and implementing iterators.
The Code
You are provided with a weighted_graph.hpp file, which includes all the basic definitions you will need (and it can be done with just those - I made sure). You made add extra methods, classes, structs etc., as long as they don't interfere with the operation of the tests. You may not include any further classes from the standard library in any of your marked code. You have also been provided with a main.cpp for ad-hoc testing purposes. This file does not form part of the assignment, and will not be marked. You can do anything you like with it. When the -run- button is pressed, it will compile and run main.cpp. When the -submit- button is pressed, your code will be run against the tests. Note that as this is C++, if your code causes a program crash (e.g. a segfault), the testing code cannot recover, and will fail to mark your work - if you get this, make sure you fix that problem first!
You have full access to the workspace for the assignment, so all the features are there, including terminal access if you so desire it.
Weighted Graphs
As the abstract data structure, and the possibilities for implementing it, have been covered in the lectures, I won't repeat them here. Please refer to the lecture material for the technical details in this regard. However, don't hesitate to ask questions etc. - you're welcome to inquire, I just don't want to clutter this space up!
The weighted_graph Class
weighted_graph is probably the most complicated C++ class you will have had to implement, but it bears a great resemblance to many of the things we've already done, so just break it down into smaller, more manageable tasks. The code itself is commented to indicate the purpose of each method. Again, to avoid clutter, I won't repeat it all here, but do not hesitate to ask if anything is unclear (there's a forum specifically for the assignment).
The assignment will be marked against three components: functionality, design and style.
Functionality will be marked exclusively by the tests, and constitutes 50% of the total mark (note that the marks for the tests add up to 50 - so they give you the percentage you will get as well).
Design will be marked in your Week 9 tutorial by your tutor and constitutes 35% of the total mark. It does not depend on the functionality of your code. You may be asked questions by your tutor to help them test your understanding of your code. It will be marked qualitatively against the following rubric:
• Pass The code shows basic understanding of how to employ data
structures to achieve a goal. The design should avoid unnecessary
data structures and should make reasonable use of
iteration and recursion when appropriate.
• Credit The design shows a solid understanding of data structures and
demonstrate effective use of control structures to achieve the
program’s goals.
• Distinction The design shows a high degree of understanding of how to
use data structures to achieve a goal efficiently, and demonstrate
some evidence that the design does not use unnecessary
resources. The design should be clean and efficient.
• High Distinction The design demonstrates a high degree of understanding of
data structures and how to efficiently employ them to build
algorithms that not only meet technical goals, but support
maintenance and future development.
Style will also be mark in your Week 9 tutorial by your tutor. It will be marked qualitatively against the following rubric:
• Pass The code mostly uses some formatting standard and is somewhat
• Credit The code adheres well to a formatting standard and variables
are well named.
• Distinction At least as well formatted as for Credit standards, along with
sufficient inline commenting to explain the code.
• High Distinction Excellent formatting and variable naming. Excellent, judiciously
employed comments that explain the code without just
repeating the code.
Marking Schedule
All being well, assuming you submit before the deadline and attend your Week 9 tutorial (in the class you are actually enrolled in - exceptions will only be made for cases where attendance at your enrolled tutorial is impossible), we aim to return the marks for the assignment within a week of the tutorial. However, we reserve the right to delay this schedule should technical problems arise.
You will submit your work with the -submit- button on Ed. No other submissions will be accepted. You are welcome to develop your code elsewhere, if that suits your workflow, but remember it must compile and run on Ed. We are using the clang++ compiler set to C++11 standard for this assessment, so avoid using C++17 only features. However code that compiles with g++ should also work with clang++ (unless you're doing something weird - so check first!).
Due Date
The assignment is due before midnight on the Friday of Week 8, which should be the 11th of May (but it's 4:23 am when I'm writing this, so check that date).
Plagiarism Checking
All code will be checked for student misconduct and plagiarism using specialised code similarity detection software.
