Required (mandatory) assignments

Note: The assignments and lab slots for reporting the assignments are scheduled during VT2. Information about the assignments will be added here.

The laboration series consists of a series of programming assignments to be presented gradually to a laboration assistant. To pass the lab series you need to have passing grade on all requiered (mandatory) assignments. General guidelines can be found here.

The assignments should be handed in before their respective deadlines, as outlined below.

IMPORTANT NOTE ON DEADLINES (updated 21/3/2017): May 24 and June 7 are the HARD deadline for the assignments. May 24 is the last date for demonstration of, and handing in the code for, the assignments before the exam. We STRONGLY recommend that you have your demonstration and hand in your code and documentation before this date. From this date up until the exam, the TAs will not answer any questions about the labs. Please use this time to study for the exam. For those assignments that still require "more work", the final, hard deadline is on June 7, at 17.00. This is the last date for demonstration of, and handing in the code for, the assignments. Contact your lab assistant and schedule a suitable time. After the deadline you will only be allowed to hand in assignment solutions during the exam periods for the TDDD93 course in August, but only if you have previously passed at least assignments 1 and 2. The hard deadline to hand in the assignments during the August exam period will be at the date of the TDDD93/TEN2 exam (during that period).

From the date of the hard deadlines, there will be a two week window during which you have one chance to address the TA's concerns and resubmit an improved version: One week for the TA to mark the assignment and one week for you to address his/her concerns. Please take the TA's concerns seriously and address them as carefully as possible. If you have problems keeping a deadline, please contact your lab assistant as soon as possible.

Assignment series overview

  • Similar to in your future work life, many of these labs have more than one solution/answer and require that you to digg through various sources of information (including the assignments instructions themselves, textbooks, online resources, and other resources that you may find credible and helpful) to identify the most important information and what you need to reach a solution. You may therefore need to read the instructions multiple times, revisit the information in the instructions (and other resources), and search for yet new information as you refine your solution. At times, you may also need to try new paths as you learn how to best tackle the problem and learn more about each assignment.
  • With a lot of available information, you may in some cases need to read the full instructions multiple times to determine what is expected from you. In fact, in assignments such as assignment 2, a non-trivial part of the assignment is to determine the requirements and identify the steps to get there. (Note that we have been nice and "sprinkled" some hints for you on the way.)
  • You are also required to carefully explain your solutions and findings both verbally and in a written report. Please take this as a learning opportunity to communicate your solutions and findings.
  • Assignment 2 and 4 require substantially more work than assignment 1 and 3. Therefore, please make sure to finish assignment 1 quickly so that you stay on pace with the assignment series.
  • The lab slots are primarily to demonstrate the labs and ask questions to the TAs. Outside that, you are expected to allocate the time necessary for you and your lab partner to complete the assignments.

Registering in Webreg
  • Register here
  • Deadline: Friday, March 25, 23:59

The assignments are done in groups of two. Only in very special cases can labs be done alone. You should register yourself (and your lab partner) before you can do the assignments. In total each student will have 5 assignments split accross 12 lab opportunities.

The schedule for each lab group is listed in timeedit.

We use the webreg system to register and administer lab groups and your results. Please sign up as soon as possible. Teaching assistants and markers for the assignments are

  • GRA: Vengatanathan Krishnamoorthi
