Add Assignment

See Sample Assignment to learn and test adding assignments by adding a sample assignment.

You can add a new assignment by clicking on "Add" in "Assignments" page. You will see this page:

Add Assignment

There are several settings in "Add Assignment" page:

Assignment Name

The assignment will be shown with this name in list of assignments.

Start Time

Users will not be able to submit before "Start Time".

Use this format for start time: MM/DD/YYYY HH:MM:SS e.g. 08/31/2013 12:00:00

Finish Time, Extra Time

Users will not be able to submit after Finish Time + Extra Time.

Late submissions (submissions in extra time) will be multiplied by a coefficient. You should write a PHP script for calculating the coefficient in "Coefficient Rule" field.

Use this format for finish time: MM/DD/YYYY HH:MM:SS e.g. 08/31/2013 23:59:59

Extra time must be in minutes. You can use *. e.g. 120 (2 hours) or 48*60 (2 days)

Participants

Enter usernames of participants here (comma separated). Only these users are able to submit. You can use keyword ALL for allowing all users to submit.

e.g.

admin, instructor1 , instructor2 ,student1  ,   student2,student3 , student4

Tests

You can upload test cases in a zip file with this structure.

Open

You can open or close the assignment for students using this option. If you close the assignment, non-student users will still be able to submit.

Scoreboard

You can enable or disable scoreboard for the assignment using this option.

Java Exceptions

You can enable or disable showing java exceptions to students. Changing this option does not affect previously judged codes.

The exception name will be shown only if tester/java_exceptions_list contains that name.

If you enable this feature, something like this will be displayed to students when an exception is thrown:

Test 1
ACCEPT
Test 2
Runtime Error (java.lang.ArrayIndexOutOfBoundsException)
Test 3
Runtime Error (java.lang.ArrayIndexOutOfBoundsException)
Test 4
ACCEPT
Test 5
ACCEPT
Test 6
ACCEPT
Test 7
ACCEPT
Test 8
Runtime Error (java.lang.ArrayIndexOutOfBoundsException)
Test 9
Runtime Error (java.lang.StackOverflowError)
Test 10
Runtime Error (java.lang.ArrayIndexOutOfBoundsException)

Coefficient Rule

You can write a PHP script here that calculates the coefficient multiplied by scores. Your script must put coefficient (from 100) in variable $coefficient. You can use variables $extra_time and $delay. $extra_time is the total extra time given to users in seconds (the extra time that you entered in Extra Time field) and $delay is number of seconds passed from finish time (can be negative).

This PHP script should not contain <?php , <? , ?> tags.

In this example, $extra_time is 172800 (2 days):

if ($delay<=0)
  // no delay
  $coefficient = 100;

elseif ($delay<=3600)
  // delay less than 1 hour
  $coefficient = ceil(100-((30*$delay)/3600));

elseif ($delay<=86400)
  // delay more than 1 hour and less than 1 day
  $coefficient = 70;

elseif (($delay-86400)<=3600)
  // delay less than 1 hour in second day
  $coefficient = ceil(70-((20*($delay-86400))/3600));

elseif (($delay-86400)<=86400)
  // delay more than 1 hour in second day
  $coefficient = 50;

elseif ($delay > $extra_time)
  // too late
  $coefficient = 0;

Problems

Problems

Enter information about problems in this field. There are several items in this field.

Name

The name of problem.

Score

The score of problem.

Time Limit

You can set a time limit in milliseconds for running codes. Python and Java are usually slower than C/C++. So they need more time.

Memory Limit

Set memory limit in kilobytes. This memory limit is not very accurate.

Allowed Languages

Set allowed languages for each problems in this field (comma separated).

Available languages are: C, C++, Java, Python 2, Python 3, Zip, PDF

Note: You can use Zip or PDF only if you have enabled Upload Only option.

e.g. C, C++ , Zip or Python 2,Python 3 or Java ,C

Diff Command

The command used to compare output with correct output. By default Sharif Judge uses diff. But you can change this command here.

This field should not contain any space.

Diff Arguments

You can set arguments of Diff command here. See man diff for a complete list of available diff arguments.

I have added two new options: ignore and identical.

  • ignore: Sharif Judge ignores all newlines and whitespaces.
  • identical: Sharif Judge doesn't ignore anything. Output of submitted file must be identical to the test case's output to be accepted.

This field should not contain any space. You may consider using -b, -bB, -iw or ignore.

Upload Only

If you set a problem as Upload-Only, Sharif Judge will not judge submissions of that problem. You can use Zip and PDF in allowed languages if you have enabled this option.
