JUDGES’ RESPONSES
 
Run Judgments
Solutions to problems submitted for judging are called runs. Each run is judged as accepted (“YES”) or rejected, and the team is notified of the results, via PC^2. Rejected runs are marked based on the following table:

           | <Completed> | Run-time | Time-limit |

-----------+-------------+----------+------------+

Wrong      |             |          |            |

-----------+-------------+----------+------------+

No Output  |             |          |            |

-----------+-------------+----------+------------+

Incomplete |             |          |            |

-----------+-------------+----------+------------+

Excessive  |             |          |            |

-----------+-------------+----------+------------+

Format     |             |          |            |

-----------+-------------+----------+------------+

YES        |             |          |            |

-----------+-------------+----------+------------+

Explanations of the above categories are as follows:

• Wrong (Output) - One or more of the outputs is a wrong value.  For example, a problem asking for the solution of 2+2 would get this response for any value other than 4
• No Output - Self explanatory
  
• Incomplete (Output) - In this case, the output provided was correct, but not all output was present.  For example, a program asking for the sum of 2+2 and the sum of 3+3 would get this response if its only output were 4 (or 6).
• Excessive (Output) - A submission receives this response if all of the correct output is present, but there is extraneous output provided, that wasn’t asked for.  For example, in the case of the example above, if the output produced was 4, 6, 8, then this response would be returned.
• (Output) Format - Some problems require that output be formatted in a certain way.  For example, they may ask for a blank line between data sets or a certain number of spaces to indent.  If a run produces the exact correct output values, has no missing values, and has no excessive values, but presents the output in a way other than that specified by the problem statement, this response would be returned.

Thus you can receive the following PC^2 judgments from the table above: 

• Completed - Wrong Answer
• Completed - No Output
• Completed - Incomplete Output
• Completed - Excessive Output
• Completed - Output Format Error
• Completed - YES (the only true YES in the table)
  
• Runtime Error - Wrong Answer
• Runtime Error - No Output
• Runtime Error - Incomplete Output
• Runtime Error - Excessive Output
• Runtime Error - Output Format Error
• Runtime Error - Correct Output (which does not count as a YES, due to the exception that occured)
• Time Limit Exceeded - Wrong Answer
• Time Limit Exceeded - No Output
• Time Limit Exceeded - Incomplete Output
• Time Limit Exceeded - Excessive Output
• Time Limit Exceeded - Output Format Error
• Time Limit Exceeded - Correct Output (which does not count as a YES, due to lack of program termination)
  

Note that you can also get a Compilation Error
 
A run can only receive ONE of the above responses.  In the case of multiple possible responses, the response provided by the judges will be the one deemed most “helpful.”  As an example, Output Format Error will never be returned when one of Excessive Output or Incomplete Output also applies.  However, this is a case-by-case decision.  Suffice it to say that a run may have more than one thing wrong with it, but you will receive only one response!
 
PROBLEM QUERIES
During the contest, teams may have questions concerning the problem statements.  There is a mechanism in PC^2 that automates this process.  Details of this process are in your PC^2 Team Guide.
 
The basic procedure is for a team to specify the problem they have a question about, type in the question, and send it to the judges via the network.  Judges may reply, again via PC^2, directly to the team, or may “broadcast” their response to all the teams.
 
Do not expect an immediate reply.  Judges must carefully consider how to answer the queries.  Teams at all sites will see the responses to all “broadcast” responses to queries.
 
In some cases, the response to your question may be “No Response”.  If you receive this, it means that the judges feel that your question is answered by a full and careful reading of the problem statement.
