PLDS210 Programming Languages and Data Structures ------------------------------------------------------------------------ Course Synopsis This course will focus on data structures and algorithms for manipulating them. Data structures for storing information in tables, lists, trees, queues and stacks will be covered. Some basic graph and discrete transform algorithms will also be discussed. You will also be introduced to some basic principles of software engineering: good programming practice for "long-life" software. For a full list of topics to be covered, view the table of contents page for the lecture notes. Lectures - 1998 There are two lectures every week: Monday 12 pm AG11 Tuesday 12 pm AG11 ------------------------------------------------------------------------ Lecture Notes A set of notes for this course is available on the Web. From the table of contents page you can jump to any section of the course. There is a home page set up for student information: http://www.ee.uwa.edu.au/internal/ug.courses.html On which, you will find an entry for course information; you can follow the links to this page and the notes themselves. You can also go directly to the PLSD210 page: http://www.ee.uwa.edu.au/~plsd210/ds/plds210.html Note that the Web pages use the string plds (programming languages and data structures) - a historical accident, which we retain because this label describes the content more accurately! Printed Notes For a ridiculously low price, you can obtain a pre-printed copy of the notes from the bookshop. You are strongly advised to do so, as this will enable you to avoid laboriously taking notes in lectures and concentrate on understanding the material. (It will also save you a large amount of time printing each page from a Web browser!) The printed notes accurately represent the span of the course: you will be specifically advised if examinable material not appearing in these notes is added to the course. (But note that anything appearing in laboratory exercises and assignments is automatically considered examinable: this includes the feedback notes!) However, the Web notes are undergoing constant revision and improvement (comments are welcome!) so you are advised to browse through the Web copies for updated pages. You'll be advised in lectures if there is a substantial change to any section. Textbooks The material on data structures and algorithms may be found in many texts: lists of reference books in the library are part of the Web notes. The Web notes are, of necessity, abbreviated and should not be considered a substitute for studying the material in texts. Web browsers Web browsers have varying capabilities: the notes were checked with Netscape 2 - but should read intelligently with other browsers. If you have problems, I would be interested to know about them, but please note that updating these notes, adding the animations, tutoring and marking your assignments for this course have priority: problems with other browsers, your home computer, etc, will only be investigated if time permits. Using the notes The notes make use of the hypertext capabilities of Web browsers: you will find highlighted links to subsidiary information scattered throughout the text. Occasionally these links will point to Web resources which may be located off campus and take some time to download: you may find it productive to use the "Stop" facility on the browser to abort the current fetch - you can try again later when the Net is less heavily loaded. In all cases, the browser's "Back" command should take you back to the original page. Program source Example source code for programs will sometimes pop up in a separate window. This is to enable you to scan the code while referring to the notes in the main page. You will probably need to move the source code page out of the way of the main page. When you have finished with the source code page, select File:Close to close the window. Selecting File:Exit will close the window and exit from Netscape - possibly not your intention! ------------------------------------------------------------------------ Tutorials - 1997 Exercises for the tutorials and laboratory sessions are also found in the Web pages. Tutorial Times Weeks Time Location Groups Thursday 9 am E273 2ic,2it1-3 4-13 Wednesday 3 pm A205 rest The first tutorial will be in the fourth week of semester. As long as one tutorial group does not become ridiculously overloaded, you may go to whichever tutorial suits you best. Laboratory Sessions - 1998 There will be two formal introductory laboratory sessions early in the semester - watch these pages for the final details. These sessions will be in laboratory G.50. After the first two laboratories, a tutor will be available in G.50 every week at times to be advertised. The tutor will advise on any problems related to the whole course: assignments, lecture material, etc. You will be able to complete the assignment on any machine which has an ANSI C compiler. Assignments will be submitted electronically: submit programs on the SGI machines and on the NT systems in 1.51 may be used - refer to the submission instructions. Note that you are expected to write ANSI standard C which will run on any machine: programs which won't run on our SGI's risk failure! In 1998, Java programs written to an acceptable standard will also be accepted. (The standard required for C is set out explicitly: ensure that you understand how to translate the important elements of this to Java before starting work in Java. Seek feedback if uncertain!) Assignments - 1998 Four assignment exercises will be set for the semester. You should be able to complete most of the first two assignments during the initial laboratory sessions. The 3rd and 4th are more substantial. Completed assignments (which should include a summary report, the program code and any relevant output) should be submitted by following the submission instructions at the end of the Web page. Performance on the assignments will be 20% of your overall assessment for the unit. Assignments 1 & 2 These will be relatively short and should require only 1 or 2 hours extra work to complete. They will be marked on a 4 point scale (Good,Marginal,Poor,Zero) and contribute 6% of your final assessment. These assignments will provide some feedback on what is expected for the remaining two assignments. You may even find that you can use the (corrected) code from these assignments in the later assignments. Assignments 3 & 4 For these two assignments, you will be expected to implement one algorithm and test another. You will be assigned an algorithm to implement as assignment 3. You may obtain from one of your class colleagues an implementation of any other algorithm and test it for assignment 4. You must submit them by the dates shown on the assignment sheets. They will constitute the remaining 14% of your assignment assessment. A minimum standard must be obtained in the assignments to pass the unit as a whole. Failure to attempt the assignments will put you at a severe disadvantage in the exam. Assignment reports Each assignment submission should be accompanied by a summary report. The report should be clear and concise: it is unlikely that you will need to write more than 2 A4 pages (or about 120 lines of text). Report Format The report should be in plain ASCII text. The 'native form' of any wordprocessor will be rejected. If you prefer to use a word processor to prepare your report, then ensure that you export a plain text file for submission when you have finished: all word-processors have this capability. This allows you to concentrate on the content of the report, rather than the cosmetics of its format. However, the general standards for report structure and organisation (title, authors, introduction, body grouped into related paragraphs, conclusion, etc) expected for any other unit apply here also. Communication This course attempts to be "paperless" as much as possible! Assignments will be submitted electronically and comments will be emailed back to you. Please ensure that your reports include email addresses of all authors. The preferred method for communication with the lecturer and tutor(s) is, at least initially, email. All routine queries will be handled this way: we will attempt to respond to all email messages by the next day. If you have more complex problems, email for an appointment (suggest a few times when you will be free). You may of course try to find me in my office at any time (but early in the morning is likely to be a waste of time), but emailing for an appointment first ensures you some priority and enables you to avoid wasting a trip to the 4th floor when there may be zero probability of success! ------------------------------------------------------------------------ Continue on the lecture notes. ------------------------------------------------------------------------ John Morris, 1996
